Twenty patients with benign prostatic hypertrophy were treated with an anti-androgenic agent, chlormadinone acetate ( Prostal ), 50 mg daily for 3 months. As a control, 20 patients with prostatic hypertrophy were treated with Eviprostat which was a non-hormonal remedy consisting of plant extracts 6 tablets daily for the same duration. Subjective symptoms of 14 patients (70%) in the Eviprostat group and 18 cases (90%) in the Prostal group were improved significantly. Although there were no significant changes in size or weight of the prostate after 3 months in the patients in the Eviprostat group as measured by transrectal ultrasonotomography, remarkable reduction in size and weight of the prostate was observed after 3 months in 11 patients (55%) in the Prostal group. Four cases complained of impotency during Prostal treatment, but no other side effects to the hepatic and/or renal functions were observed.
