With the lifetime risk of being diagnosed with prostate cancer so great, an effective chemopreventive agent could have a profound impact on the lives of men. Despite decades of searching for such an agent, physicians still do not have an approved drug to offer their patients. In this article, we outline current strategies for preventing prostate cancer in general, with a focus on the 5-α-reduct...

The aim of the study was to estimate morphology in the testis and epididymis of adult rats, treated with finasteride for 28 days (the time period of two seminiferous epithelium cycles) and 56 days (the time period of one spermatogenesis). A 28 days long DHT deficiency did not significantly influence the structure of seminiferous epithelium. After 56 days of treatment, finasteride induced slough...

      In this work we sought to determine whether vesicles (liposomes/niosomes) were able to enhance finasteride concentration in the dermis layer, including the pilosebaceous units (PSU). Such enhancement could be beneficial in the treatment of some androgen-related skin disorders. Hamster flank skin was used to study  <span styl...

BACKGROUND The Prostate Cancer Prevention Trial (PCPT) was a randomized, double-blind, placebo-controlled study of the efficacy of finasteride in preventing prostate cancer in 18,882 men aged 55 years or older. The PCPT offered an opportunity to prospectively study the effects of finasteride and other covariates on sexual dysfunction. METHODS We assessed sexual dysfunction in 17,313 PCPT part...

INTRODUCTION The development of effective medications makes pharmacological therapy of BPH the dominant mode of treatment today. It improves urinary symptoms and prevents disease progression while producing side effects on male sexual function. OBJECTIVE The aim of the study is to present the effects of BPH pharmacological treatment on the occurrence of sexually adverse effects in men: change...

Three sensitive spectrophotometric methods are presented for the determination of finasteride in bulk and in tablets. The methods rely on the use of bromate-bromide reagent and three dyes namely, methyl orange, indigocarmine and thymol blue as reagents. They involve the addition of a measured excess of bromate-bromide reagent to finasteride in acid medium, and after the bromination reaction is ...

BACKGROUND The objective of this study was to elucidate the prophylactic effects of 5-alpha reductase inhibitor (e.g., finasteride) and a pure antiandrogen (e.g., casodex) on rat prostate carcinogenesis and to determine whether latent prostate carcinoma can be prevented to develop to clinically significant cancer by use of these drugs. METHODS F344 rats were subcutaneously administered 3,2'-d...

Androgens have profound effects on scalp and body hair in humans. Scalp hair grows constitutively in the absence of androgens, while body hair growth is dependent on the action of androgens. Androgenetic alopecia, referred to as male pattern hair loss (MPHL) in men and female pattern hair loss (FPHL) in women, is due to the progressive miniaturization of scalp hair. Observations in both eunuchs...

Objective: Hirsutism is the presence of excess terminal hairs in females in a male-like pattern. The most accepted hypothesis for the development of hirsutism is increased 5-α reductase activity in hair follicles of hirsute women. Based on this hypothesis, this study is designed to evaluate the effects of finasteride cream (a 5-α reductase inhibitor) on idiopathic hirsutism. Methods: Forty wome...
