Follow-Up of 1 mg Finasteride Treatment of Male Pattern Baldness,Difference between Clinical Trials and Private Office Follow-Up: Influences on Prescribing Habits Evaluated

DERMATOLOGIC SURGERY, Issue 5 2004
Marvin J. Rapaport MD
Background. Finasteride (Propecia) was approved by the FDA in 1998 for treating men with androgenetic alopecia. The published clinical trials demonstrated statistical differences between drug and placebo. Rarely do new drugs undergo further non-drug-company-sponsored studies of efficacy. Concerns about clinical studies and marketing of drugs prompted this evaluation of a large group of patients taking this medication. Objective. Finasteride usage offered an opportunity not only to understand the acceptance of a cosmetically oriented medication, but also to evaluate subjective comments and compliance after a long period of time. Methods. A total of 1261 patients were monitored with phone calls every 3 months after finasteride was initially prescribed. After 12 months, a detailed questionnaire was sent to all patients with an additional letter and two telephone calls if no response was received. Statistical analysis of the patients' data was made. Results. Thirty-two percent or 414 men continued to take finasteride daily for 1 to 3 years. Twenty-four percent or 297 men discontinued the drug between 3 and 15 months owing to poor results. The remaining 44% or 549 men were lost to follow-up despite numerous attempts to contact them. Conclusion. A total of 414 men continued to take the medication, but only 211 returned detailed questionnaires. A small percentage of this group felt that they grew hair. The remaining patients noted poor results. [source]

Effects of Finasteride (1 mg) on Hair Transplant

DERMATOLOGIC SURGERY, Issue 10 2005
Matt Leavitt DO
Background. The improved scalp coverage achieved by hair transplant for men with androgenetic alopecia can be diminished by continued miniaturization and loss of preexisting, nontransplanted hairs. Objectives. To evaluate whether finasteride 1 mg, administered daily from 4 weeks before until 48 weeks after hair transplant, improves scalp hair and growth of nontransplanted hair in areas surrounding the transplant and to evaluate the safety and tolerability of finasteride for men undergoing hair transplant. Methods. In this randomized, double-blind, placebo-controlled study, 79 men with androgenetic alopecia (20,45 years of age) were assigned to treatment with finasteride 1 mg (n = 40) or placebo (n = 39) once daily from 4 weeks before until 48 weeks after hair transplant. Efficacy was evaluated by review of global photographs by an expert dermatologist and by macrophotography for scalp hair counts. Results. Treatment with finasteride resulted in significant improvements from baseline, compared with placebo, in scalp hair based on global photographic assessment (p < .01) and hair counts (p < .01) at week 48. Visible increases in superior/frontal scalp hair post-transplant were recorded for 94% and 67% of patients in the finasteride and placebo groups, respectively. Finasteride treatment was generally well tolerated. Conclusion. For men with androgenetic alopecia, therapy with finasteride 1 mg daily from 4 weeks before until 48 weeks after hair transplant improves scalp hair surrounding the hair transplant and increases hair density.

Finasteride treatment alters MMP-2 and -9 gene expression and activity in the rat ventral prostate

INTERNATIONAL JOURNAL OF ANDROLOGY, Issue 1 2010

Summary The safety of using finasteride as a prevention of prostate cancer is still under debate. In this study, we investigated the effects of finasteride on the location, gene expression and activities of matrix metalloproteinases -2 and -9, which are involved in the degradation of extracellular matrix components during tissue remodelling and prostate cancer progression, invasion and metastasis. Ventral prostates (VP) from Wistar rats treated with finasteride (25 mg/kg/day) for 7 and 30 days and age-matched controls were evaluated using histology, immunohistochemistry, semi-quantitative RT-PCR and gelatin zymography. Finasteride treatment reduced the epithelial immunostaining of MMP-2 but increased MMP-9 immunostaining in the epithelial cells and in the stroma. The mRNA expression of both MMP-2 and MMP-9 were significantly increased on day 7 of finasteride treatment, mainly for MMP-9 and returned to the control levels by day 30. However, gelatin zymography showed that MMP-9 activity was significantly increased on day 7 of finasteride treatment and remained elevated on day 30 (p < 0.05), while MMP-2 activity was reduced after 30 days of treatment. Finasteride increases MMP-9 and reduces MMP-2 activities in the prostate, which may affect negatively and positively both normal and tumoural prostatic cell behaviour during the treatment. Studies on expression of MMPs in the prostate during different androgen manipulation or cancer chemoprevention strategies can contribute to understand the tissue's overall response and clinical data.

Changes in molecular forms of prostate-specific antigen during treatment with finasteride

BJU INTERNATIONAL, Issue 7 2002
F. España
Objective ,To study the influence of finasteride treatment on the molecular forms of prostate-specific antigen (PSA) in patients with benign prostatic hyperplasia (BPH). Patients and methods ,Total PSA, free PSA and PSA complexed to ,1 -antichymotrypsin (PSA-,1ACT) were measured in plasma and serum from 40 men with BPH and a total PSA of <,20 ng/mL, using in-house and commercial immunoassays, before and during treatment with finasteride (30 men) or placebo (10 men). Results ,The baseline values were not significantly different between the groups, with mean (sd) total plasma PSA levels of 3.6 (4.3) and 4.8 (5.9) ng/mL in the finasteride and placebo groups, respectively. Finasteride, but not placebo, induced a significant reduction in total PSA, free PSA and PSA-,1ACT levels in plasma and serum (P < 0.001). However, complexed-to-total (c/t) and free-to-total (f/t) PSA ratios remained constant in both groups, both in plasma and serum, during the follow-up. Conclusion ,The decrease in total PSA after finasteride treatment results from a proportional reduction in its two major molecular forms, free PSA and PSA-,1ACT, which explains why the c/t and f/tPSA ratios do not change significantly despite treatment. This suggests that routine analysis of molecular forms of PSA could improve the utility of the change in total PSA associated with finasteride for the early diagnosis of prostate cancer. It also suggests that any subsequent change in both ratios, particularly an increase in c/tPSA or a decrease in f/tPSA ratio, could be considered an early sign of neoplastic degeneration rather than a therapeutic consequence.
