The drug-nutrient interaction has aroused interest in research in the area of nutrition in order to avoid unwanted responses to nutritional therapy. In children, the failure to provide adequate nutrients can adversely affect both weight development and growth. To investigate the potential drug-nutrient interactions that occur in hospitalized pediatric patients. Descriptive and cross - sectional study with non - probabilistic sampling for convenience. The research was carried out by consulting the medical records and information of the nutrition service of the pediatrics sector of the University Hospital of the Federal University of Maranhão, in the Maternal and Child Unit, from August to November 2018. For the identification of potential interactions the website www.interacoesmedicamentosas.com. br and relevant scientific literature were used. A descriptive analysis of the results was performed, being presented by means of percentages and frequency distribution of the variables involved. The prescriptions of 76 patients were verified, with a mean of 28.3 ± 37.2 months. Of these, 50% were males. The mean number of prescriptions was 5.98. Among the 76 individuals, 60 (78.9%) observed possible interactions, and one patient presented five and four patients presented four. The results presented in this study reinforce the need for future research that may guide patient care aiming at the standardization of drug administration simultaneously to enteral nutrition to avoid drugnutrient interactions in order to obtain the desired clinical results.

Background: Hospital drug therapy has the potential for incidents, thus it is necessary to identify situations that may compromise patient safety. Objective: To investigate potential drug-drug interactions caused by the overlapping of medications planned by nurses in the patients' prescriptions at a hospital inpatient unit. Methodology: Descriptive, cross-sectional study of documentary analysis with a quantitative approach, of 260 prescriptions for adult patients. Potential drug- interactions were identified using the Drug Interaction Checker (Medscape®). Results: A total of 3066 doses were analyzed, with a concentration of 4 schedules, showing an institutional standardization of schedules. The omission error rate was 5.44%. Drug-drug interactions of moderate severity were more frequent, especially lopinavir/clonazepam and diazepam/tramadol combinations. Conclusion: Omission errors and interactions can be minimized with tools to support clinical decision and reconfiguration of the work process. [ABSTRACT FROM AUTHOR]

Objective: To investigate in the scientific literature the most frequent clinical repercussions derived from drug interactions in the intensive care setting. Method: Integrative review, performed in seven databases. Eligibility criteria were: observational, descriptive, analytical and / or case report studies; involving human beings in the context of clinical practice. Duplicate articles have been deleted. Results: Seventeen articles were selected, which indicated the propensity of bleeding and bruising arising from the interaction between Warfarin and Valproic Acid as more evident, followed by associated syndromes, such as long QT syndrome and serotonergic syndrome. Conclusion: In the event of a drug interaction, knowing the clinical repercussions may favor quick and assertive decision making minimizing potential complications associated with safety.

Objective: to profile prescribers and users of psychotropic drugs and verify possible drug interactions. Method: retrospective and cross-sectional study. The sample consisted of prescriptions for drugs subjected to special control, from lists C and B, dispensed from January to March 2017 for a total of 1344 patients treated at a private pharmacy in the municipality of Cascavel, Paraná. Results: the prescriptions were mostly for females. Regarding the prescriber's specialty, 423 (31.5%) were psychiatrists. Possible drug interactions were found in 335 (24.9%) patients, of which 206 (61.5%) were moderate and 129 (38.5%) were severe. Of those patients with potentially serious interactions, 90 (70%) used more than one medication in the same class, in the same period. In contrast, only 12 (5.83%) of patients with moderate interactions had therapeutic duplicity. Conclusion: the present study identified a high frequency of drug interactions involving psychotropic drugs and an association between therapeutic duplication and possible serious type interactions, as well as a high prevalence of serious interactions in psychiatrist prescriptions and psychotropic use by women.

Objective: To characterize severe potential drug interactions in maternal intensive care, and to determine their frequency, risk factors and potential risk medications. Methods: An observational and longitudinal study conducted between December 2014 and December 2015 in a maternal intensive care unit. Clinical data were collected and severe potential drug interactions were identified on pregnant inpatients. The drug interactions were classified by type, prevalence and exposure rate. A multivariate logistic regression model was used to identify the severe potential drug interactions and the related drugs (p<0.05). Results: A total of 95.1% of patients were exposed to, at least, one potential drug interaction; in that, 91.7% 33.9% were related to, respectively, moderate and severe potential drug interactions. The patients were exposed, on average, on 69.2% of days they were in the intensive care unit. The main drugs involved in more severe drug interactions were magnesium sulfate, metoclopramide, propranolol and diazepam. Conclusion: The severe potential drug interactions were observed in almost all patients of the study, and, approximately one third of those interactions were related to greater severity and resulted in exposure during long hospital stay. The higher number of prescribed drugs and its previous use of medications at home increase the occurrence of severe potential drug interactions. [ABSTRACT FROM AUTHOR]

Interações medicamentosas (IM) exacerbam o risco de eventos adversos graves relacionados ao uso de benzodi­azepínicos. Este estudo objetivou conhecer aspectos relacionados à utilização de flumazenil em pacientes hospitalizados. Através do método observacional, foram analisados prescrições e prontuários de 31 pacientes internados entre junho/2008 e junho/2010 quanto à indicação do flumazenil, aos fatores que podem ter contribuído para intoxicação por benzodiazepínicos e à frequência de IM potenciais (IMP). A frequência de indicação para reversão de sedação excessiva foi aproximadamente 1,3 prescrições por 1.000 pacientes. Foram identificadas IMP em 84% dessas prescrições. Para sete casos, não houve pre­scrição prévia de benzodiazepínicos. O exame permitiu a identificação dos eventos com necessidade do manejo da sedação excessiva relacionados à ocorrência de IMP entre benzodiazepínicos e outros medicamentos para um elevado percentual de pacientes. Observou-se que idade elevada, quadro clínico com muitas comorbidades e administração de medicamentos com interações bem definidas estiveram associados à hipersedação. ABSTRACT Drug interactions (DIs) heighten the risk of severe adverse events connected with use of benzodiazepines. This observational study aimed to ascertain aspects of use of flumazenil in hospital inpatients. The prescriptions and medical records of 31 patients admitted between June 2008 and June 2010 were examined for indication of flumazenil, factors that could have contributed to benzodiazepine intoxication, and potential drug interaction (PDI) frequency. In 1.3 prescriptions per 1,000 patients the indication was for reversal of excessive sedation. PDIs were observed in 84% of these prescriptions. In 7 cases there was no prior prescription of benzodiazepines. The examination identified events requiring management of excessive sedation associated with occurrence of PDI between benzodiazepines and other drugs in a high percentage of patients. It was observed that more advanced age, clinical condition with many comorbidities, and administration of drugs with well-defined interactions were observed to associate with over-sedation.

A retrospective study evaluating hepatic laboratory alterations and potential drug interactions in patients treated for onychomycosis. We evaluated 202 patients, 82% female. In 273 liver enzyme tests, there were changes in only 6%. Potential drug interactions were identified in 28% of patients for imidazole and 14% for terbinafine. The risk of potential interactions increased with the patient's age and use of multiple drugs.Estudo retrospectivo avaliando alterações laboratoriais hepáticas e potenciais interações medicamentosas em pacientes tratados para onicomicose. Foram avaliados 202 pacientes, sendo 82% do sexo feminino. Em 273 exames de enzimas hepáticas, houve alterações em apenas 6%. Potenciais interações medicamentosas foram identificadas em 28% dos pacientes para imidazólicos e 14% para terbinafina. O risco de interações potenciais aumentou com a idade do paciente e o uso de múltiplas medicações.

OBJETIVO: Analisar a relação entre interação medicamentosa potencial e reinternação hospitalar. MÉTODOS: Estudo retrospectivo com 1.487 pacientes maiores de 18 anos admitidos em um hospital geral em Vitória da Conquista, BA, de janeiro a dezembro de 2007. Os dados foram extraídos da Autorização de Internação Hospitalar do Sistema de Informação Hospitalar do Sistema Único de Saúde. O relacionamento probabilístico foi empregado para combinar múltiplas autorizações de uma mesma internação em um único registro e para identificar readmissões. Informações sobre prescrições foram agregadas manualmente aos registros do Sistema de Informação Hospitalar. Regressão logística foi utilizada para quantificar a influência de interação medicamentosa potencial e reinternação. Regressão de Cox foi empregada para testar a influência dessa variável no tempo até a primeira reinternação. RESULTADOS: Foram identificadas 99 readmissões (7% dos pacientes). Interação medicamentosa potencial foi encontrada em 35% das prescrições analisadas. Pacientes com potencial de interação medicamentosa na admissão prévia foram mais propensos à reinternação. A razão de chance ajustada indicou que esses pacientes tinham chance 2,4 vezes maior de readmissão; a taxa de risco ajustada mostrou que em pacientes com interação medicamentosa esse risco foi 79% maior (p < 0,01). CONCLUSÕES: Os resultados encontrados neste trabalho sugerem associação entre exposição à interação em internação prévia e risco aumentado de reinternação. Os profissionais de saúde devem atentar para os riscos potenciais de certas combinações medicamentosas e monitorar cuidadosamente pacientes em maior risco, como aqueles com insuficiência renal ou idosos.OBJETIVO: Analizar la relación entre potencial interacción medicamentosa potencial y reinternación hospitalaria.

METHODS: Retrospective study with 1,487 adult patients (> 18 years old) admitted to a general hospital in the city of Vitória da Conquista, Northeastern Brazil, from January to December 2007. Data were collected from Hospital Admission Authorization (AIH) forms in the Brazilian National Health System Hospital Database (SIH/SUS). Probabilistic linkage was used to combine multiple AIH forms from the same admission into a single record and to identify readmissions. Information on prescriptions was manually added to the SIH/SUS records. Logistic regression was used to quantitatively assess the impact of drug interactions on hospital readmissions. Cox regression was performed to test the impact of this variable on time to first readmission. RESULTS: A total of 99 readmissions (7% of all patients) were identified. Potential drug interactions were found in 35% of all prescriptions evaluated. Patients with potential drug interactions in a prior admission were more likely to be readmitted. The adjusted odds ratio indicated a 2.4-fold increase in odds of being readmitted; and the adjusted hazard ratio showed that this risk was increased by 79% in patients with potential drug interactions (p < 0.01). CONCLUSIONS: The study results suggest an association between prior drug interactions and increased risk of readmission. Health professionals should be aware of potential hazard of certain drug combinations and closely monitor high-risk patients such as elderly patients and those with renal impairment.

This study analyzed potential drug interactions (PDIs) of antimicrobials used in patients of hematopoietic stem cell transplantation and identified associated factors. The sample consisted of 70 patients admitted to a hospital in São Paulo. The PDIs were analyzed through the consultation of the Drug Interactions Facts and Drug Interactions Handbook. Descriptive statistics and logistic regression were used. Half of the sample was exposed to 13 PDIs, which occurred with fluconazole (53.8%), ciprofloxacin (30.8%) and sulfamethoxazole-trimethoprim (15.4%). Most (92.3%) were of moderate severity, with good evidence (61.6%), early delayed effect (61.5%) and need to have their therapy monitored (76.9%). Patients with four or more medications (pEl estudio analizó interacciones medicamentosas potenciales (IMP) de antimicrobianos usados en pacientes sometidos a trasplante de células madre hematopoyéticas e identificó los factores asociados las IMP.

Interação medicamentosa é um evento clínico em que os efeitos de um fármaco são alterados pela presença de outro fármaco, fitoterápico, alimento, bebida ou algum agente químico ambiental. A incidência de reações adversas causadas por interações medicamentosas é desconhecida. Contribui para esse desconhecimento o fato de não se saber o número de pacientes aos quais foram e são prescritas as combinações de medicamentos com potencial para interações. Não é possível distinguir claramente quem irá ou não experimentar uma interação medicamentosa adversa. Possivelmente, pacientes com múltiplas doenças, com disfunção renal ou hepática e aqueles que fazem uso de muitos medicamentos são os mais suscetíveis. Dentre as condições que colocam os pacientes em alto risco para interações medicamentosas está o grupo de portadores de doenças autoimunes. Além de apresentarem um risco para o paciente e um insucesso para o profissional da saúde, as interações medicamentosas podem aumentar muito os custos da saúde. O objetivo desta revisão é abordar as interações clinicamente importantes das drogas mais usadas em reumatologia (exceto os anti-inflamatórios não esteroide e corticosteroides) com o intuito de auxiliar os prescritores reumatologistas no desafio de intervir farmacologicamente nos processos de doença, buscando melhores desfechos para os pacientes e menores gastos com a complexa terapêutica das doenças crônicas sob sua responsabilidade.Drug interaction is a clinical event in which the effects of a drug are altered by the presence of another drug, phytochemical drug, food, beverage, or any environmental chemical agent. The incidence of adverse reactions caused by drug interactions is unknown. This lack of information is compounded by not knowing the number of patients who are prescribed combinations of drugs that can potentially interact. Patients who will or will not experience an adverse drug interaction cannot be clearly identified. Those with multiple diseases, with kidney or liver dysfunction, and those on many drugs are likely to be the most susceptible. Patients with autoimmune diseases are at higher risk for drug interactions. In addition to representing a risk for the patient and jeopardizing the health care provided by professionals, drug interactions can increase dramatically health care costs. This review article approached the clinically relevant interactions between the most used drugs in rheumatology (except for non-steroidal anti-inflammatories and corticosteroids) aiming at helping rheumatologists to pharmacologically interfere in the disease processes, in the search for better outcomes for patients and lower costs with the complex therapy of chronic diseases they deal with.

Os objetivos principais do tratamento da tuberculose são curar o paciente e minimizar a possibilidade de transmissão do bacilo para indivíduos saudáveis. Reações adversas ou interações das drogas antituberculose entre si e com outros fármacos podem causar modificação ou descontinuação da terapêutica. Descrevemos os mecanismos gerais de ação, absorção, metabolização e excreção dos medicamentos utilizados no tratamento da tuberculose multidroga resistente (aminoglicosídeos, fluoroquinolonas, cicloserina/terizidona, etionamida, capreomicina e ácido para-aminossalicílico). Descrevemos as reações adversas e as interações (com medicamentos, alimentos e antiácidos) assim como a abordagem mais adequada para situações especiais, como gravidez, amamentação, insuficiência hepática e renal.The main objectives of tuberculosis therapy are to cure the patients and to minimize the possibility of transmission of the bacillus to healthy subjects. Adverse effects of antituberculosis drugs or drug interactions (among antituberculosis drugs or between antituberculosis drugs and other drugs) can make it necessary to modify or discontinue treatment. We describe the general mechanism of action, absorption, metabolization, and excretion of the drugs used to treat multidrug resistant tuberculosis (aminoglycosides, fluoroquinolones, cycloserine/terizidone, ethionamide, capreomycin, and para-aminosalicylic acid). We describe adverse drug reactions and interactions (with other drugs, food, and antacids), as well as the most appropriate approach to special situations, such as pregnancy, breastfeeding, liver failure, and kidney failure.

Adverse effects of antituberculosis drugs or drug interactions (among antituberculosis drugs or between antituberculosis drugs and other drugs) can make it necessary to modify or discontinue treatment. We briefly review the new guidelines for the pharmacological treatment of tuberculosis, introduced by the Brazilian National Ministry of Health in 2009, and describe the general mechanism of action, absorption, metabolization, and excretion of the first-line drugs used in the basic regimen. We describe adverse drug reactions and interactions (with other drugs, food, and antacids), as well as the most appropriate approach to special situations, such as pregnancy, breastfeeding, liver failure, and kidney failure. We also describe the mechanisms by which the interactions among the antituberculosis drugs used in the basic regimen can cause druginduced hepatitis, and we discuss the alternatives in this situation.

O controle da dor e seus eventos adversos são focos de profissionais e gestores das instituições de saúde para obtenção de desfechos assistenciais. O estudo teve como objetivos analisar a prevalência de combinações e interações medicamentosas da terapia analgésica e verificar a associação dessa com os eventos adversos conferidos. Trata-se de estudo descritivo, exploratório e retrospectivo. A amostra foi composta por 260 prontuários de pacientes submetidos a hemorroidectomia, com idade de até 60 anos hígidos. Os resultados mostraram que as associações medicamentosas mais utilizadas foram a dipirona+omeprazol (33,7%), dipirona+cetoprofeno (23,6%) e cetoprofeno+lactulose (22,8%). Observou-se que cetoprofeno+ omeprazol (p=0,001) e cetoprofeno+ lactulose (p=0,03) estiveram significativamente relacionados com sangramento. Concluiu-se que, com exceção do cetoprofeno, as outras associações medicamentosas identificadas no estudo se mostraram seguras para serem utilizadas no período pós operatório.El control del dolor y sus eventos adversos se constituyen en el foco de los profesionales y gestores de las instituciones de salud para la obtención de resultados asistenciales.

The objectives of this study were to analyze the prevalence of medicine combination and interaction and to verify the association of this with the observed adverse effects. It was a descriptive, exploratory and retrospective study. The sample was composed by 260 patient data submitted to hemorrhoidectomy, up to 60 years old, healthy. Results showed that the mostly used medicine associations were dipyrone sodium and omeprazole (33.7%), dypirone sodium and ketoprofen (23.6%) and cetoprofen and lactulose (22.8%). It was observed that ketoprofen + omeprazole (p=0.001) and ketoprofen + lactulose (p=0.03) were significantly associated with bleeding. It was observed that, excepting ketoprofen, the other medicine association identified in the study showed to be safe to be used in the post surgical period.

The aims of this study were to investigate the prevalence and to describe the most frequent potential interactions between antidepressants and antihypertensive and glucose lowering drugs in the HIPERDIA Program at two primary care units in Coronel Fabriciano, Minas Gerais State, Brazil. Data were collected through the patient registry in the HIPERDIA Program and the local psychoactive drug dispensing system. Interactions were classified as due to pharmacokinetic and/or pharmacodynamic mechanisms. Prevalence of antidepressant use in the HIPERDIA Program was 4.37% (29 of patient 663 records). Of the HIPERDIA patients in treatment with antidepressants, 19 were exposed to 47 interactions, 23.4% of which involving pharmacokinetic, 61.7% pharmacodynamic synergy, and 15.9% simultaneous pharmacokinetic and pharmacodynamic mechanisms. Complications can arise from drug-drug interactions, a situation that can escape the attention of prescribing health professionals.O objetivo do estudo foi investigar a prevalência e descrever as possíveis interações de medicamentos mais freqüentes entre antidepressivos e anti-hipertensivos/hipoglicemiantes do programa HIPERDIA de duas unidades básicas de saúde do Município de Coronel Fabriciano, Minas Gerais, Brasil. A coleta de dados foi realizada mediante consulta ao caderno de cadastro dos pacientes usuários do programa de HIPERDIA e pela consulta ao sistema de dispensação de psicotrópicos do município. As interações foram classificadas segundo o mecanismo farmacocinético e farmacodinâmico. A prevalência do uso de antidepressivos em pacientes do HIPERDIA foi de 4,37% (29 de 663 cadastros analisados). Dos pacientes do HIPERDIA em tratamento com antidepressivos, 19 estão expostos a 47 interações, 23,4% delas ocorrem por mecanismos farmacocinéticos, 61,7% por mecanismos farmacodinâmicos de sinergismo e 15,9% interagem das duas formas simultaneamente. Complicações podem ser provocadas por interações entre fármacos e os profissionais prescritores podem não estar atentos a tal fato.

This study assessed potential drugs interactions in intensive care patients at a university hospital in Ceará, northeast Brazil. Of 102 patients studied, 72.5% were exposed to 311 potential drug-drug interactions; 64% of them were females aged 60 years or more and hospital stay was at least 9 days. A statistically significant association was found between number of drugs used and the occurrence of drug interactions. A total of 1,140 drugs were scheduled to be administered concomitantly; of these, 74% had potential for drug interactions. As for the classification of these events, 48.2% had a pharmacokinetic profile; 55.4% were of slow onset; 54.7% had moderate severity; and 60.6% were well-documented in the literature. The most common clinical action taken was "to monitor signs and symptoms". Nursing staff can perform 80% of preventive actions to avoid undesirable effects of drug interactions. However, nurses need to have adequate knowledge about drug action mechanisms and triggering factors associated to drug interactions.Este estudio investigó interacciones medicamentosas (IM) potenciales en una Unidad de Terapia Intensiva (UTI) en un hospital universitario del Ceará. De los 102 pacientes del estudio, 72,5% presentaron 311 potenciales IMs. De estos, 64% eran del sexo femenino, con edad mayor o igual a 60 años y tiempo de internación mayor o igual a nueve días. Hubo una asociación estadísticamente significativa entre el número de medicamentos y la ocurrencia de IM; 1.140 medicamentos fueron administrados durante el mismo horario, entre estos, 74% presentaron potencial para IM. En lo que se refiere a la clasificación de las IMs, 48,2% presentaron un perfil fármaco cinético, 55,4% inicio demorado, 54,7% moderada gravedad y 60,6% bien documentadas en la literatura. El manejo clínico más frecuente fue "observar señales y síntomas". Ochenta por ciento de las intervenciones para evitar los efectos indeseables de las IMs pueden ser realizadas por el enfermero. Sin embargo, para que estas ocurran, de hecho, es importante que el enfermero conozca los mecanismos farmacológicos de las IMs, así como sus factores precipitantes.Este estudo investigou interações medicamentosas (IM) potenciais em uma Unidade de Terapia Intensiva (UTI) de um hospital universitário do Ceará. Dos 102 pacientes do estudo, 72,5% apresentaram 311 potenciais IMs. Desses, 64% eram do sexo feminino, com idade maior ou igual a 60 anos e tempo de internação maior ou igual a nove dias. Houve associação estatisticamente significativa entre o número de medicamentos e a ocorrência de IM, e 1 140 medicamentos foram aprazados no mesmo horário. Desses, 74% apresentaram potencial para IM. Quanto à classificação das IMs, 48,2% apresentaram perfil farmacocinético, 55,4% início demorado, 54,7% moderada gravidade e 60,6% bem documentadas na literatura. O manejo clínico mais freqüente foi "observar sinais e sintomas". Oitenta por cento das intervenções para evitar os efeitos indesejáveis das IMs podem ser realizadas pelo enfermeiro. No entanto, para que essas ocorram, de fato, é importante que o enfermeiro conheça os mecanismos farmacológicos das IMs, bem como seus fatores precipitantes.

OBJETIVOS: Interações medicamentosas ocorrem quando os efeitos e/ou a toxicidade de um fármaco são alterados pela presença de outro. São geralmente imprevistas e indesejáveis. Realizado estudo com objetivo de verificar a prevalência e o valor clínico das interações medicamentosas potenciais em unidades de terapia intensiva. MÉTODOS: Incluídos todos pacientes de três unidades de terapia intensiva em um período de 2 meses, analisados transversalmente. Foram excluídos aqueles com tempo de permanência menor que 2 dias. Os dados foram tabulados de acordo com as combinações de fármacos observadas no período de 24 horas. A presença e o valor clínico das interações medicamentosas potenciais foram conferidos ao final do seguimento. RESULTADOS: Analisados 140 pacientes, 67,1% apresentaram alguma interações medicamentosas potenciais significativa e das 1069 prescrições, 39,2% tiveram este achado. De 188 interações medicamentosas potenciais diferentes, 29 foram consideradas altamente significativas. Por análise univariada, observou-se no grupo que apresentou interação significativa maior quantidade de medicamentos, fármacos/dia, número de médicos prescritores e tempo de internação na unidade de teapia intensiva. Por modelo de regressão logística multivariada, apenas o número de fármacos/dia correlacionou-se com o aumento do risco de interação medicamentosa potencial significativa (p = 0.0011); o uso de mais que 6 medicamentos/dia aumenta em 9.8 vezes este risco. CONCLUSÕES: Pacientes em unidades de terapia intensiva estão submetidos a alto risco de interações medicamentosas potenciais e o número de fármacos/dia é condição com alto valor preditivo positivo para tal. Os intensivistas devem ser alertados para o reconhecimento do problema e criados mecanismos para o manejo adequado e prudente, diminuindo iatrogenias.OBJECTIVES: Drug interactions occur when effects and/or toxicity of a drug are affected by presence of another drug. They are usually unpredictable and undesirable. A study was conducted to verify the prevalence and clinical value of potential drug interactions in intensive care units METHODS: All patients, of three intensive care units were included in a cross-sectional study, over a period of two months. Patients with less than a 2 days length of stay were excluded. Data were collected from twenty-four hour prescriptions and all possible paired combinations drug-drug were recorded. Prevalence and clinical value (significance) were checked at the end of follow-up. RESULTS: One hundred and forty patients were analyzed, 67.1% presented with some significant potential drug interactions and of the 1069 prescriptions, 39.2% disclosed the same potential. Of 188 different potential drug interactions, 29 were considered highly significant. Univariate analysis showed that in the group with significant potential drug interactions a higher number of different drugs, drugs/day had been used, there were more prescribing physicians and extended stay in intensive care units. Adjusted to the multivariate logistic regression model, only the number of drugs/day correlated with increased risk of significant potential drug interaction (p = 0.0011) and, furthermore that use of more than 6 drugs/day increased relative risk by 9.8 times. CONCLUSIONS: Critically ill patients are submitted to high risk of potential drug interactions and the number of drugs/day has a high positive predictive value for these interactions. Therefore, it is imperative that critical care physicians be constantly alert to recognize this problem and provide appropriate mechanisms for management, thereby reducing adverse outcomes.

O objetivo do estudo foi caracterizar o perfil dos medicamentos e identificar combinações decorrentes da co-administração de antimicrobianos potencialmente interativos e outros agentes. 70 prescrições médicas de pacientes submetidos a transplante de medula óssea (TMO), todos internados no Instituto do Coração, São Paulo, Brasil, foram analisadas. Os medicamentos foram classificados de acordo com o sistema Alfa, e o potencial de interação e as características farmacológicas foram listados a partir da literatura. Na analise dos dados utilizou-se estatística descritiva. Verificou-se que 72,7% dos medicamentos apresentaram potencial interativo, destacando-se os precipitadores (79,2%) e o fluconazol (85,7%) como o antimicrobiano mais envolvido nas combinações, associado ao omeprazol em 40% da amostra. Nos pacientes de TMO, a co-administração de medicamentos potencialmente interativos foi freqüente, condição que, associada à polifarmácia e ao aprazamento simultâneo de horários na administração desses agentes, poderia predispor o paciente a eventos indesejados, afetando, deste modo, a segurança da terapia.El objetivo del estudio fue determinar el perfil de medicamentos e identificar combinaciones por administración conjunta de antimicrobianos potencialmente interactivos y otros agentes. Fueron analizadas 70 prescripciones médicas de pacientes sometidos a trasplante de médula ósea (TMO), todos internados en el Instituto del Corazón, São Paulo, Brasil. Los medicamentos fueron clasificados según el sistema Alfa. El potencial de interacción y las características farmacológicas fueron establecidas según la bibliografía. El análisis de datos a través de estadística descriptiva. El 72,7% de los medicamentos mostró potencial interactivo, destacándose los precipitadores (79,2%) y como antimicrobiano más utilizado en las combinaciones el fluconazol (85,7%), siendo asociado al omeprazol en 40% de la muestra. La combinación de medicamentos potencialmente interactivos fue frecuente en estos pacientes, condición que asociada a la polifarmacia y a la distribución simultánea de horarios en su administración podría predisponer al paciente a efectos adversos, afectando la seguridad en el tratamiento.The study aimed at characterizing the profile of the drugs and identify combinations between potentially interactive anti-microbial drugs used in patients who underwent bone marrow transplantation (BMT). The analysis covered 70 prescription medications for BMT patients hospitalized at Instituto do Coração, São Paulo, Brazil. Medications were classified according to the Alpha system, listing their interactive potential and pharmacological characteristics according to literature. Data were analyzed through descriptive statistics. Results showed that 72.7% of drugs presented an interactive potential, with precipitators (79.2%) and fluconazole (85.7%), high-lighted as the most involved anti-microbial in the combinations, associated to omeprazole in 40% of the samples. BMT patients were frequently administered combinations of potentially interactive drugs. This condition, when associated with simultaneous schedules, could predispose patients to undesirable events, thus affecting the security of the therapy.

The article had the purpose of commenting on studies on polypharmacy in the elderly, focusing on diagnosis and control. Polypharmacy is defined as the use of a number of medications at the same time and the use of additional drugs to correct drug adverse effects. The fact that the elderly take more medications for the treatment of several diseases makes them more susceptible to the occurrence of adverse reactions. Prophylactic actions such as balanced prescriptions are vital to reduce the incidence of these reactions and prevent longer hospital stay, increased costs and aggravation of the elderly health condition.O artigo teve por objetivo comentar estudos sobre polifarmácia em idosos, particularmente em diagnose e controle. O conceito de polifarmácia considera o uso de diversos medicamentos ao mesmo tempo, além da utilização de um fármaco para corrigir o efeito adverso de outro. Por consumirem mais medicamentos para o tratamento de diversas doenças, os idosos são mais vulneráveis ao surgimento de reações adversas. Medidas profiláticas, como a prescrição balanceada, são de fundamental importância para diminuir essas reações, tendo em vista o aumento do tempo de internação, gasto e piora do quadro de saúde do idoso.

The elderly are highly vulnerable to problems stemming from drug use. This is due to pharmacokinetic and pharmacodynamic changes of aging itself, the multiple and complex diseases and concomitant use of several drugs. In this sense, the present study aimed at evaluating potential pharmacotherapeutic problems of the elderly in a Unit of Primary Healthcare of Minas Gerais. This is a descriptive cross-sectional study of 100 elderly. The convenience sample was calculated based on the total of elderly enrolled in the Health Unit. Data were collected through interviews, from which we obtained sociodemographic data related to the use of medications, health conditions, among others. 117 potential drug therapy problems and 2 duplicates, 7 overdoses, 72 potential drug-drug interactions and 8.5% inappropriate drugs for the elderly, according to the Beers Criteria, were identified. These results are worrying and highlight the need to implement monitoring of drug therapy services in Primary Healthcare Units seeking to improve the quality of life for seniors.

The identification and the interaction of drugs are directly related to patient's safety and are highly relevant within the hospital. Current analysis identifies and evaluates potential drugs interactions within prescribed pharmacotherapy. The study, undertaken between August and December 2015, comprises 308 prescriptions of 195 patients hospitalized in the UTI of a university hospital. Micromedex® database identified interactions. Further, 101 out of 308 prescriptions revealed at least one drug interaction, with a total of 173 interactions with 71 patients, of which 43 were males with an average age of 61,9 years. Mean hospitalization period in the ICUs was 7 days. The 101 prescriptions with drug interactions totaled 1,349 drugs, at an average of 13,3 drugs/patient/day. The identification of these interactions avoids therapeutic failure and toxicity. [ABSTRACT FROM AUTHOR]

OBJECTIVE: To assess the frequency of combination of antidepressants with other drugs and risk of drug interactions in the setting public hospital units in Brazil. METHODS: Prescriptions of all patients admitted to a public hospital from November 1996 to February 1997 were surveyed from the hospital's data processing center in São Paulo, Brazil. A manual search of case notes of all patients admitted to the psychiatric unit from January 1993 to December 1995 and all patients registered in the affective disorders outpatient clinic in December 1996 was carried out. Patients taking any antidepressant were identified and concomitant use of drugs was checked. By means of a software program (Micromedex®) drug interactions were identified. RESULTS: Out of 6,844 patients admitted to the hospital, 63 (0.9%) used antidepressants and 16 (25.3%) were at risk of drug interaction. Out of 311 patients in the psychiatric unit, 63 (20.2%) used antidepressants and 13 of them (20.6%) were at risk. Out of 87 patients in the affective disorders outpatient clinic, 43 (49.4%) took antidepressants and 7 (16.2%) were at risk. In general, the use of antidepressants was recorded in 169 patients and 36 (21.3%) were at risk of drug interactions. Twenty different forms of combinations at risk of drug interactions were identified: four were classified as mild, 15 moderate and one severe interaction. CONCLUSION: In the hospital general units the number of drug interactions per patient was higher than in the psychiatric unit; and prescription for depression was lower than expected.OBJETIVO: Verificar a freqüência de combinações de antidepressivos com outros medicamentos e o risco de interações medicamentosas em um hospital público no Brasil. MÉTODOS: Prescrições de todos os pacientes internados em um hospital público, em São Paulo, SP, de novembro de 1996 a fevereiro de 1997 foram analisadas pelo centro de processamento de dados do hospital. Foi realizada busca manual de todos os prontuários de pacientes internados na enfermaria de psiquiatria do hospital de janeiro de 1993 a dezembro de 1995, assim como de todos os pacientes registrados no ambulatório de doenças afetivas em dezembro de 1996. Foram identificados os pacientes que usaram algum antidepressivo e as drogas utilizadas concomitantemente. Foram identificadas pelo programa Micromedex® as interações medicamentosas. RESULTADOS: Dentre os 6.844 pacientes internados nas enfermarias gerais (não psiquiátricas) do hospital, 63 usaram antidepressivos (0,9%) e 16 (25,3%) usavam medicações com risco de interação. Dentre os 311 pacientes da enfermaria de psiquiatria, 63 (20,2%) usavam antidepressivos e 13 (20,6%) apresentavam risco de interação. Dos 87 pacientes do ambulatório de doenças afetivas, 43 (49,4%) usavam antidepressivos e 7 (16,2%) apresentavam risco. Em geral, o uso de antidepressivos foi encontrado em 169 pacientes e 36 (21,3%) estavam em risco de interação medicamentosa. Vinte diferentes tipos de interações foram identificados, sendo 4 leves, 15 moderados e um grave. CONCLUSÕES: Nas enfermarias gerais o número de interações medicamentosas foi superior em relação à enfermaria de psiquiatria; e o número de prescrições de antidepressivos foi menor do que o esperado.

Objective: To evaluate the incidence of potential drug-drug interactions in an intensive care unit of a hospital, focusing on antimicrobial drugs. Methods: This cross-sectional study analyzed electronic prescriptions of patients admitted to the intensive care unit of a teaching hospital between January 1 and March 31, 2014 and assessed potential drug-drug interactions associated with antimicrobial drugs. Antimicrobial drug consumption levels were expressed in daily doses per 100 patient-days. The search and classification of the interactions were based on the Micromedex® system. Results: The daily prescriptions of 82 patients were analyzed, totaling 656 prescriptions. Antimicrobial drugs represented 25% of all prescription drugs, with meropenem, vancomycin and ceftriaxone being the most prescribed medications. According to the approach of daily dose per 100 patient-days, the most commonly used antimicrobial drugs were cefepime, meropenem, sulfamethoxazole + trimethoprim and ciprofloxacin. The mean number of interactions per patient was 2.6. Among the interactions, 51% were classified as contraindicated or significantly severe. Highly significant interactions (clinical value 1 and 2) were observed with a prevalence of 98%. Conclusion: The current study demonstrated that antimicrobial drugs are frequently prescribed in intensive care units and present a very high number of potential drug-drug interactions, with most of them being considered highly significant.

This study proposes to measure frequency and to characterize the profile of potential drug interactions (pDDI) in a general medicine ward of a teaching hospital. Data about identification and clinical status of patients were extracted from medical records between March to August 2006. The occurrence of pDDI was analyzed using the database monographs Micromedex® DrugReax® System. From 5,336 prescriptions with two or more drugs, 3,097 (58.0%) contained pDDI. The frequency of major and well document pDDI was 26.5%. Among 647 patients, 432 (66.8%) were exposed to at least one pDDI and 283 (43.7%) to major pDDI. The multivariate analysis identified that factors related to higher rates of major pDDI were the same age (p< 0.0001), length of stay (p< 0.0001), prevalence of hypertension [OR=3.42 (p< 0.0001)] and diabetes mellitus [OR=2.1 (p< 0.0001)], cardiovascular diseases (p< 0.0001) and the number of prescribed drugs (Spearman's correlation=0.640622, p< 0.0001). Between major pDDI, the main risk was hemorrhage (50.3%), the most frequent major pDDI involved combination of anticoagulants and antiplatelet drugs. Among moderate pDDI, 3,866 (90.8%) involved medicines for the treatment of chronic non-communicable diseases, mainly hypertension. In HU-USP, the profile of pDDI was similar among adults and elderly (the most frequent pDDI and major pDDI were same), the difference was only the frequency in either group. The efforts of the clinical pharmacists should be directed to elderly patients with cardiovascular compromise, mainly in use of anticoagulants and antiplatelet drugs. Furthermore, hospital managers should increase the integration between levels of health care to promote safety patient after discharge. [ABSTRACT FROM AUTHOR]

The combination of antiretroviral agents of the rescue therapy in the Syndrome Immunodeficiency Acquired increases the risks of drug and food interactions. The aim in this study was to analyze the risk to drug and food interactions in the use of the antiretroviral therapy with drugs of the rescue by 40 AIDS patients of a quaternary hospital of the northwest region of the State of São Paulo. This is an exploratory, descriptive study, with an approach quantitative and qualitative that it was realized in the period between 2012 and 2013. The patients were interviewed through a questionnaire developed by the multidisciplinary healthcare team. The interviews were conducted by team of pharmacists. The interactions were evaluated by computerized databases. The scheme composed by darunavir, enfuvirtide, lamivudine, raltegravir and ritonavir was the most used (32.5%) by the patients. The antiretroviral drugs that more presented risk to food interactions were ritonavir, darunavir and tenofovir, in 31 (77.5%), 29 (72.5%) and 21 (52.5%) patients, respectively. Were identified 87 potential drug interactions and seven interactions were classified as major level. In this study all prescriptions presented risks to drug interactions and this demonstrated the need of monitoring. However, the most of the drug interactions was beneficial and result of the potentiating of the therapeutic effect as consequence of the synergism between the drugs of the antiretroviral therapy. The interaction between pharmacists and prescribers can help to provide to rational and safe pharmacotherapy to the patient. [ABSTRACT FROM AUTHOR]

Pharmacotherapy in Bipolar Disorder (BD) aims to reduce the frequency and severity of episodes. Our goal was to identify drug interactions in bipolar patients through a cross-sectional study in a tertiary hospital. We identified 150 patients in which 84 were selected, who were polymedicated and / or with comorbidities and / or bad adhesion. However, there was a contact with 51 of those patients and only 36 agreed to participate. Data collection was performed by analysis of medical records and interview. The classification of interactions only considered those which were found in at least two reputable bibliographies, and were classified according to severity, only considering the moderate and the severe ones. 36 interactions were identified, being: among non-psychiatric drugs (9), between non-psychoactive and psychotropic drugs (12), between drugs and alcohol (5) and among psychiatric drugs (10). Most were moderate severity (31), but five were considered severe, in which three triggered cardiotoxicity. The patients mainly used: mood stabilizers (32), antipsychotics (26) and diuretics (16). Our findings suggest that serious drug interactions for bipolar polymedicated patients can trigger other complications, such as heart toxicity associated with tachycardia. The identification and monitoring of patients with bipolar disorder may contribute to an improvement in the therapeutic conduct and well being of the patient. [ABSTRACT FROM AUTHOR]

The practice of drug combinations is common in hospitalized patients. This practice is often necessary, especially in psychiatric patients, since other comorbidities may occur in parallel with neuropsychiatric disorders. However, this practice may favor the occurrence of drug interactions with consequent increase of different adverse effects. Facing this situation, the present study aimed to evaluate the occurrence of potential drug interactions with benzodiazepines prescribed to hospitalized patients at the Psychiatric Clinic of the Hospital Regional de Assis - SP, in order to generate information that contributes to the effectiveness of the treatment provided to patient. To this end, an analysis of 100 medical prescriptions was performed, in which were evaluated the possibility of drug interactions between the different medications from the class of benzodiazepines concomitantly administered, as well as other classes of drugs. By means of this study, it was verified that the 100 analyzed prescriptions 93 presented the possibility of different pharmacological interactions between benzodiazepine, and with other classes of drugs, totaling 356 possible interactions. Of this total stand out the associations of benzodiazepines with antipsychotics, antihistamines, antiepileptics and antidepressants, which can enhance the expression of numerous adverse effects, highlighted the exacerbation of depressant effect on the central nervous system, with effects that can range from mild clinical manifestation until risk of lethal outcome. In this context, it seeks in this work to contribute to a better understanding, recognition and early or prophylactic intervention in clinical situations arising from interactions between different pharmacological classes of drugs with benzodiazepines.

Drug interactions consist in modulating effects of a drug by prior or simultaneous administration of another drug or through association with food or other chemicals. It may or may not result in harm to health. This study aimed to investigate the potential drug interactions (PDI) in drug prescriptions developed in November 2011 in a psychiatric outpatient clinic, in Feira de Santana, Bahia. The medications prescribed were grouped by Anatomical Therapeutic Chemical (ATC) system. The PDIs were identified and classified according to the Micromedex®, using criteria of severity, mechanism of action, onset and scientific knowledge. 782 prescriptions were analyzed, containing 23 different drugs, totaling 2258 prescribed drugs, categorized into 7 pharmacological groups, with a predominance of antipsychotics (33%), especially haloperidol (17.1%). Among the most common PDI (N=1711), haloperidol and promethazine (15.7%), chlorpromazine and promethazine (11.1%), chlorpromazine and haloperidol (10.4%) were predominant. It was found 56 different types of PDI, 57.1% of moderate severity, 48.2% with good documentation, 60.7% with pharmacokinetic mechanism and 57.1% with latency period not specified. Studies can contribute to reducing risks associated with PDI, enabling a more effective and safe pharmacotherapy. The role of the clinical pharmacist can contribute to the rational prescribing of psychoactive drugs. [ABSTRACT FROM AUTHOR]

Objective: To identify the occurrence of potential drug interactions in prescriptions for adult patients admitted to the Emergency Department of Hospital São Paulo. Methods: A cross-sectional and descriptive study. Its sample consisted of 200 medical prescriptions. The analysis of drug interactions was performed using the Drugs.com database, where they are classified according to severity of interaction as severe, moderate, mild and without interaction. Results: The number of drugs in prescriptions ranged from 2 to 19, and the average per prescription was 4.97 drugs. A total of 526 potential drug interactions were identified in 159 prescriptions (79.5%); in that, 109 were severe, 354 moderate, 63 mild interactions, and 41 showed no interaction. Conclusion: This study demonstrated potential drug interactions in 79.5% of prescriptions examined in the Emergency Department. Drug interactions can occur at any time when using medications and, during this working process, the nursing staff is involved in several steps. Therefore, training the nursing staff for the rational use of drugs can increase safety of care delivered to patients. [ABSTRACT FROM AUTHOR]
