Abstract

Purpose We determined the effect of Prostataplex™ in men with lower urinary tract symptoms associated with benign prostatic hyperplasia. Materials and Methods A total of 92 Chinese men between 49 and 75 years old with lower urinary tract symptoms were randomly assigned in this double-blind, placebo controlled trial. The 46 patients in the intervention group were given 2 Prostataplex soft gels daily for 12 weeks, while the 46 in the control group were given 2 placebo soft gels for the same time. Results The treated and control groups appeared to have more than a 95% compliance rate, as judged by counting the remaining pills in the bottle collected at the end of trial months 1 to 3. After 12 weeks of intervention the mean ± SD maximum urinary flow rate was significantly higher in the treatment group than in the control group (14.07 ± 2.56 vs 11.74 ± 1.23 ml per second, p <0.001), while relative urinary resistance was significantly lower in the treatment group than in the control group (2.35 ± 0.83 vs 3.02 ± 1.18, p = 0.002). While there was no significant difference in mean prostate volume or International Prostate Symptom Score between the 2 groups, 18 of 46 patients (39.1%) in the treatment group showed an International Prostate Symptom Score improvement (decrease of 3 or greater) after intervention, whereas only 1 of 46 (2.2%) in the control group showed an International Prostate Symptom Score improvement (chi-square test p <0.001). Conclusions Prostataplex may have short-term effects in improving symptoms and objective measures in Chinese men with lower urinary tract symptoms associated with benign prostatic hyperplasia.
