Introduction: Parkinson's Disease (PD) is the second most frequent neurodegenerative disease and dopaminergic agents are frequently used as a treatment while 'end of dose deterioration' or 'Wearing-Off (WO)' phenomenon is common with these agents. Treatment reconciliation may be helpful in this situation and there is dearth of studies especially in India. Aim: To study the WO effects in patients of PD, their pharmacotherapy and outcome. Materials and Methods: This registry-based, prospective, observational, outcomes-based study was conducted in the Department of Clinical and Experimental Pharmacology, School of Tropical Medicine, Kolkata, West Bengal, India, in collaboration with Department of Neuromedicine of Kolkata Medical College and private clinics of a Neurologist from January 2020 to December 2021. An attempt was also undertaken to make a registry of Idiopathic Parkinson's Disease (IPD) patients. WO Questionnaire 19-items (WOQ-19), Movement Disorder Society-Unified Parkinson's Disease Rating Scale (MDS-UPDRS Scale), The 39-items Parkinson's Disease Questionnaire (PDQ-39 questionnaire), The 8-items Morisky Medication Adherence Scale (MMAS scale), suspected Adverse Drug Reaction (ADR) Reporting Form of Indian Pharmacoepia commission (version 1.3), World Health Organisation-Uppsala Monitoring Centre (WHO-UMC) Scale, Naranjo causality assessment scale, Hartwig and Seigel's Severity Assessment Scale were used in the present study. The study was commenced after obtaining approval from institutional ethics committee. The data was then analysed with parametric or non parametric tests using (mean±Standard Deviation (SD), median, Fisher's-exact test, Friedman's Analysis of Variance (ANOVA) test, Wilcoxon matched pair signedrank test). Data collected and then statistically analysed by using WPS Excel version 2021 and GraphPad Prism version 9 software. Results: Total IPD patients were found to be 111 in the present study with a mean age of IPD patients as 61.85±7.20 years. Incidence of WO in the present study was found to be 40.5% among IPD patients. Most common characteristic of WO was found to be tremor in 104 (28.8%) patients followed by slowness of movement in 63 (17.5%) patients. WHO-UMC scale and Naranjo causality assesment scale both revealed 36.4% ADRs were probable category and 63.6% were possible category. MDS-UPDRS Score, PDQ-39 Score, MMAS-8 score significantly (p-value<0.05) improved during the course of treatment. Conclusion: Dose adjustment of syndopa was mostly used in the management of WO phenomenon and significant improvement in the quality of life of the patients was seen. [ABSTRACT FROM AUTHOR]

Introduction: Geriatrics is a speciality that focuses on healthcare of elderly people. Geriatric population is defined as people above 60 years of age. Geriatric population constitute 8.14% of total population in India. They have diverse physiological and pathological profiles which have an impact on the pharmacokinetic and pharmacodynamic properties of the administered drug. Very often they are under polypharmacy due to multisystem involvement and thereby subjected to numerous drug interactions and Adverse Drug Reactions (ADRs). There are few studies conducted in India regarding ADRs in Geriatric Patients and none in Odisha, India. Aim: Pharmacovigilance study in Geriatric patients was taken up in a tertiary care hospital to assess the spectrum, cause, severity and preventability of ADRs. Materials and Methods: This prospective, observational study was conducted in Department of Pharmacology in collaboration with Departments of Geriatric Medicine, Medicine and Skin and Venereal Disease (VD) of SCB Medical College and Hospital, Cuttack, Odisha, India. All geriatric patients (aged =60 years) diagnosed with ADR, from September 2016 to September 2018, were included. The detailed information of type of ADR and its characteristics were filled up in Suspected ADR Reporting Form. The prevalence and profile of ADRs in geriatric patients were studied. Their causality, severity and preventability were assessed by World Health Organisation-Uppsala Monitoring Centre (WHO-UMC) System, Modified Hartwig's Severity Scale and Schumock and Thornton Preventability Scale, respectively. Results: A total of 236 geriatric ADRs were reported in two years, out of which, the most common ADRs were cutaneous 100 (42.4%), followed by metabolic 68 (28.8%) and Gastrointestional (GI) involvement 26 (11%). Out of the geriatric ADRs, 128 (54.2%) ADRs were possible, 65% were moderate in intensity and 70.3% ADRs were probably preventable. Conclusion: Cutaneous and metabolic ADRs were most common in geriatric patients in present study. Majority of ADRs were possibly caused due to the drug used, were of moderate intensity and probably preventable. [ABSTRACT FROM AUTHOR]
