Sixty patients in Stages I and II of benign prostatic hyperplasia were treated with Peponen capsule. Out of them 26 took the drug for 10 months, 22 for at least 7, and 12 for at least 4 months. The daily dosage was 3 x 2 capsules in the first month and 3 x 1 capsule for the rest of the time. On the ground of urodynamic test results and changes in subjective complaints, more than 80% of the patients experienced improvement. The therapy intensified the uroflow, appeased dysuria, the difficult and painful discharge, and reduced the frequency of nocturnal urination.
