Androgenetic alopecia is the most common type of hair loss and affects at least 80% of men and half of women before the age of 70, with the incidence increasing with age. Androgenetic alopecia is an ailment conditioned by genetic and hormonal factors, associated with excessive stimulation of the androgen receptor in the cells of the hair follicle. With the development of medicine, more and more therapeutic methods for androgenetic alopecia appear on the market, including minoxidil, 5-α-reductase inhibitors, microneedling, platelet-rich plasma, low-energy laser therapy, rosemary oil, or siRNA. Thanks to the constantly growing amount of scientific research, progressively more is known about the mechanisms of androgenetic alopecia development and potential strategies to stop it. The article analyzes the literature using electronic databases and textbooks to compile methods that can be an effective alternative for people who do not want to undergo surgery. Some of the methods presented in the article have the potential to not only slow down, but also reverse the progression of the disease. However, each of them still has its limitations.

INTRODUCTION: Androgenetic alopecia, also known as male pattern baldness, is a common dermatological problem. It manifests as hair thinning and miniaturization of hair follicles. In recent years, knowledge of the risk factors and pathomechanisms of this disease has increased, making treatment more effective. Serious consequences of this condition include reduced quality of life and patient self-esteem. PURPOSE OF THE WORK: The purpose of this paper is to review and discuss selected studies involving agents used in the pharmacotherapy of androgenetic alopecia and to evaluate their safety and efficacy. DESCRIPTION OF THE STATE OF KNOWLEDGE: There are two drugs approved by the Food and Drug Administration (FDA) for the treatment of androgenetic alopecia - oral finasteride 1 mg and 2% or 5% minoxidil solution for topical use. There are also other preparations for external use, such as 0.1% finasteride solution or ketoconaloze shampoo, and for oral use, dutasteride. They seem to be a promising alternative for the treatment of androgenetic alopecia, but require further research. It is possible to use one drug of choice or to use combination therapy to achieve better therapeutic effects. SUMMARY: In order to achieve the best and fastest treatment results, patients should be treated with combination therapy consisting of two or more preparations. To reduce systemic side effects, consider using several topical preparations.

By way of Density Functional Theory (DFT)-based computational methods with commercially available software, the computational work of which about the molecular properties, the vibrational modes and vibrational frequencies of finasteride were accomplished for the first time. In order to gain a deeper and more thorough understanding of the molecular structure and infrared spectrum of finasteride, the equilibrium geometry harmonic vibrational frequencies and geometric parameters (bond lengths, bond angles and dihedral angles) were calculated by Generalized Gradient Approximations (GGAs) with five different density functional methods (PBE, RPBE, HCTH, PW91 and BLYP), using Material Studio 8.0 program. Theoretical vibrational frequencies and theoretical optimized geometric parameters were compared with the corresponding experimental data, which concluded that the GGA/PW91 method were shown to be in a good agreement with the results of experiment. In addition, the highest occupied molecular orbital (HOMO) energies, the lowest unoccupied molecular orbital (LUMO) energies and electron density isosurface calculations were done with an aim at a better understanding of the stability and reactivity of the molecule, indicating that the alkene and lactam conjugated system on the ring A is more likely to interact with other species. And, the atomic charge distribution was also calculated to understand the charge effect caused by electronegative atoms, which shows that the possible active-sites in chemical reactions are N1 and O1.

La alopecia frontal fibrosante (AFF) es un tipo de alopecia cicatricial cuya incidencia está aumentando de forma significativa en nuestro país. Se caracteriza por un retroceso en la línea de implantación del pelo a nivel frontotemporal que afecta mayoritariamente a mujeres postmenopaúsicas, con un impacto negativo en su calidad de vida. Se asocia a menopausia precoz en un 14% de los casos y a hipotiroidismo en un 15%. Con respecto al tratamiento, son los inhibidores de la 5alfa-reductasa, los fármacos que han demostrado mejoría de la enfermedad en un mayor número de casos. Presentamos un caso de AFF en una mujer de 77 años tratada con éxito con finasteride a dosis de 2,5mg/día. Frontal fibrosing alopecia (FFA) is a scarring alopecia whose incidence is increasing significantly in our country. It is characterized by loss of frontotemporal hairline that mostly affects postmenopausal women, with a negative impact on quality of life. It is associated with early menopause in 14% of cases and hypothyroidism in 15%. With regard to treatment, 5α-reductase inhibitors are the drugs that have shown improvement of the disease in a larger number of cases. We report a new case of FFA in a woman of 77 years successfully treated with finasteride at doses of 2.5mg daily.

OBJETIVO: Avaliar o impacto na expressão AgNORs e apoptose na próstata do hamster-Mesocricetus auratus (hMa) submetido à aplicação de finasterida. MÉTODOS: Vinte roedores da espécie hMa (n=20), machos foram separados aleatoriamente em grupos de dez animais: grupo-Finasterida (n=10) e grupo-Controle (n=10). No grupo-finasterida foi administrado 7,14 ng/mL de finasterida, subcutâneo (SC), no dorso, três vezes por semana, por 90 dias. Foi avaliada a expressão AgNORs como marcador de proliferação celular e a apoptose como marcador de morte celular. RESULTADOS: A expressão de AgNORs foi menor no grupo-finasterida, 2,846±0,877 versus 3,68 ±1,07 grumos argilófilos por micrômetro ao quadrado (µm²) no grupo-controle, p= < 0,0001. A apoptose foi mais frequente no grupo-finasterida, 53,62±1,389 versus 14,76 ± 2,137 µm² no grupo-controle, p= 0,0408. CONCLUSÃO: Observou-se diminuição da expressão de AgNORs e promoção da apoptose na próstata dos roedores em estudo, que foram submetidos à aplicação de finasterida.

- Abstract
Background: Topical minoxidil and oral finasteride are the only drugs approved for the treatment of androgenetic alopecia (AGA) in Spain. However, the management of this condition is highly variable because numerous treatments are used off-label. The main aim of this study was to describe the prescribing habits of dermatologists in Spain for male AGA (MAGA) and female AGA (FAGA)., Material and Methods: Descriptive cross-sectional study using online questionnaires completed by dermatologists working in Spain., Results: The responses of 241 dermatologists were analyzed. The most common treatments prescribed for MAGA were minoxidil (98%), oral finasteride (96%), nutricosmetics (44%), topical finasteride (37%), oral dutasteride (33%), platelet-rich plasma (14%), and low-level laser therapy (8%). For premenopausal FAGA, the most common treatments were topical minoxidil (98%), oral contraceptives (81%), nutricosmetics (72%), cyproterone acetate (58%), oral finasteride (39%), topical finasteride (39%), spironolactone (27%), platelet-rich plasma (20%), oral dutasteride (20%), oral flutamide (18%), and low-level laser therapy (7%). Finally, for postmenopausal FAGA, the most common treatments prescribed were topical minoxidil (98%), oral finasteride (84%), nutricosmetics (68%), topical finasteride (50%), oral dutasteride (35%), platelet-rich plasma (21%), spironolactone (16%), cyproterone acetate (16%), oral flutamide (9%), and low-level laser therapy (9%). A limitation of our study is that we did not analyze novel AGA treatments such as oral minoxidil and dutasteride mesotherapy., Conclusions: The most common treatments prescribed for AGA by dermatologists in Spain are topical minoxidil, oral finasteride, and nutricosmetics for MAGA and postmenopausal FAGA and topical minoxidil, oral contraceptives, and nutricosmetics for premenopausal FAGA., (Copyright © 2018 AEDV.

INTRODUCCIÓN: Después de diez años de uso clínico de Finasterida en el tratamiento farmacológico de la Hiperplasia Benigna de Próstata (HBP), nos planteamos revisar la literatura, para analizar aquellos trabajos que por diseño y calidad metodológica, nos permita aplicar recomendaciones basadas en evidencias clínicas. MATERIAL Y MÉTODOS: Utilizando las bases de datos informáticas disponibles en Medline, Embase, Healthstar, y la Cochrane Library (1990-2002), se recogieron todos los trabajos referentes a pacientes entre 50 y 85 años, con síntomas del tramo urinario inferior sugerentes de HBP y con parámetros objetivos, como flujometría, medición del volumen prostático y del residuo post-miccional, presión del detrusor, efectos adversos, costeefectividad, calidad de vida. RESULTADOS: Se encontraron un total de 137 referencias, de las cuales 36 cumplen los criterios de inclusión, que permiten su clasificación por niveles de evidencia. Tres tienen nivel I, 12 nivel II, 6 nivel III y 10 nivel IV. Tres son estudios económicos y dos evalúan calidad de vida. COMENTARIOS: Con alto nivel de evidencia y después de diez años de uso, se demuestra que Finasterida es efectivo en reducir la sintomatología en los pacientes con próstatas mayores de 40 ml y/o PSA >1,4 ngr/ml, con escasos efectos adversos y una clara mejoría en la calidad de vida, por lo que es recomendable con grado A, su uso clínico. CONCLUSIONES: Finasterida, al reducir el volumen prostático (nivel de evidencia I), modifica la evolución natural de la HBP, disminuyendo el riesgo de retención aguda de orina y de cirugía. INTRODUCTION: After ten years of clinical use of Finasteride in patientes with BPH, we carried out a systematic review of the literature including the assessment of their quality and grading the level of evidence for clinical recommendations. METHODS: Using Medline, Embase, Healthstar and Cochrane Library from 1990 until 2002, we select all the studies refering patients between 50 to 85 with symptoms of BPH, metrics of flow, prostatic volume, postmictional residue, detrusor pressure, adverse effects, cost-efecctiveness and quality of life. RESULTS: We found out 135 references, of which 36 accomplish the inclusion criteria. Of those, 3 have got level I of evidence, 12 level II, 6 level III and 10 level IV. Three are economic studies and two evaluate the quality of life. DISCUSSION: With a high level of evidence and after ten years of clinical use, Finasteride shows its effectiveness in reducing the symptoms of patients with prostate bigger than 40 ml and/or PSA of more than 1.4 ngr/ml, with scarce adverse effects with a clear improvement of quality of life. Therefore, it is recommended (grade A) for clinical use. CONCLUSIONS: Finasteride, through prostate volume reduction, modify natural evolution of BPH, decreasing the risk of acute urine retention and surgery.

Se administró 0,1 mg/kg día de Finasteride, inhibidor selectivo de la 5 αreductasa, vía oral a caninos machos adultos con diferentes grados de hiperplasia prostática benigna. Se evaluó, mediante ecografía, el efecto de la droga sobre el tamaño prostático. Finasteride provocó importante disminución del tamaño glandular y no se asoció a efectos tóxicos colaterales. La dosis utilizada fue 10 veces inferior a la utilizada por otros autores, sin embargo se lograron resultados similares a los obtenidos por los mismos. Considerando la reducción del costo del tratamiento y la ausencia de efectos tóxicos colaterales al utilizar la dosis mencionada, Finasteride sería una excelente opción para el tratamiento a largo plazo de pacientes con hiperplasia prostática benigna., Mature dogs received Finasteride, a selective 5 α reductase, orally 0.1 mg/kg/day for 10 weeks. The effect of Finasteride administration on prostatic size was evaluated using ultrasonography. Finasteride induced a marked decreasing the size of the prostate and was not associated with any side effects. Dose used was smaller than others authors, however the results were similar. In relation with small cost and absence side effects, Finasteride appears to be an alternative therapy in dogs with benign prostatic hypertrophy., Facultad de Ciencias Veterinarias

Alfuzosin ,Hiperplasia benigna de próstata ,Finasterida ,Benign prostatic hyperplasia ,Alfuzosina ,Finasteride - Abstract
La hiperplasia benigna de próstata es un aumento del tamaño de la glándula de carácter no maligno, muy corriente entre los hombres de más de sesenta años, que produce problemas en la micción. También existen problemas irritativos por aumento del tono del músculo prostático liso y del cuello vesical a través de receptores alfa-l . Para combatir el aumento del tamaño de la glándula se utiliza la supresión androgénica mientras que los fenómenos irritativos se tratan con bloqueantes alfa-I-adrenérgicos. Dentro del primer grupo, en la actualidad se utiliza una inhibidor de la 5-alfa reductasa, la finasterida, que impide la fonnación de dihidrotestosterona, que es la fonna honnonal activa en la próstata. Dentro del segundo grupo, se utiliza modernamente la alfuzosina, que es un inhibidor bastante específico de los receptores del tracto genitourinario., Benign prostatic hyperplasia is a nonmalignant enlargement of the pros tate. This condition is very common in men over sixty years of age and causes bladder outflow osbstrucion. There are also irritative symptomes produced by urethral hypertonia of neurologycal origin through alpha-l-adrenergic receptors. Androgenic suppressión is used to treat the enlargement of the prostate whereas irritative symptomes are treated with alpha-I-adrenoreceptor antagonists. Finasteride blocks the conversión of testosterone to dihydrotestosterone, which is the active fonn of the honnone in the pros tate. Alfuzosin is an alpha-l-adrenoreceptor antagonist in the genitourinary tract.
