Terazosin in the treatment of premature ejaculation: a short-term follow-up.
OBJECTIVE
The aim of the present study was to evaluate the efficacy of terazosine in patients with premature ejaculation and lower urinary tract symptoms (LUTS), after excluding other sexual disorders and chronic prostatitis.


METHODS
A total of 90 patients with premature ejaculation and LUTS were enrolled to the study after excluding sexual disorders, prostatitis and benign prostatic hyperplasia. The patients were divided into two groups. Sixty patients in group 1 were treated with terazosine 5 mg daily for a month. Patients were followed monthly and questioned for their ejaculation problem. The results were classified as cure, improvement and ineffective. If patients showed improvement and ineffectiveness, the treatment was continued with 10 mg daily for the following month. Group 2 was included 30 patients, and placebo was applied for a month. At the end of this period, in patients who did not show any improvement, terazosine 10 mg was started.


RESULTS
In the treatment group, at the 1st month follow-up, 21 patients (35%) were cured, 20 (33.3%) showed improvement. In 19 (31.7%) patients, the treatment was ineffective. In group 2, 9 (30%) patients showed improvement and the rest had no-changes after one-month follow up. There was statistically significant difference between two groups (Pearson chi2 test = 0.000). Later, terazosine 10 mg was given to the patients in group 2 and to the patients who showed improvement or unsuccessful result with terazosine 5 mg. With terazosine 10 mg, 10 (14.5%) patients were cured, 29 (42.2%) patients were improved. Finally, terazosine treatment in patients with premature ejaculation was found to be effective in 60 patients (66.7%).


CONCLUSIONS
Alpha blockers seem to be physiological medical agents in the treatment of premature ejaculation since ejaculation is under sympathetic control. Moreover, these agents are effective in lower urinary tract and they should be used in patients with premature ejaculation and lower urinary tract symptoms.
