[Double-blind placebo-controlled trial of terazosine efficacy in patients with chronic abacterial prostatitis].

A double-blind placebo-controlled trial of teraosin efficacy (Kornam, Lek, Slovenia) was made in 51 patients with chronic abacterial prostatitis/chronic pelvic pain syndrome (CAP/CPPS) of category IIla according to NIH. All the patients were given a 2-week induction course of placebo followed by teraosin treatment (5 mg/day, n = 29) or placebo (n = 22) for 8 weeks. The participants of the study were followed up for 12 months. Pretreatment differences between the groups by NIH-CPSI system, symptoms frequency scale, leukocyte count of the prostate and uroflowmetry were insignificant. Teraosin and placebo patients showed a noticeable improvement (39.7 and 9.9% by symptoms frequency scale, respectively; by 36.4 and 6.6% by the linear scale, respectively). The drug reduced pain and dysuria, improved quality of life considerably (by 36.2%). Maximal urine flow accelerated by 22.96 and 10.01% in teraosin and placebo groups, respectively. Leukocyte count fell two-fold in the study group and lowered insignificantly in the placebo group. The recurrence-free interval was 25 and 9 weeks, respectively. Thus, teraosin monotherapy improves quality of life in CAP/CPPS patients, significantly relieves symptoms and prolongs recurrence-free interval vs placebo.
