Clomipramine versus placebo in the treatment of premature ejaculation: a pilot study

This study evaluated clomipramine as a possible treatment for premature ejaculation. Twenty patients with premature ejaculation were randomly allocated to treatment with clomipramine or placebo in a double-blind study. Average estimated time to ejaculation after vaginal penetration increased to 6.1 minutes on 25 mg. of clomipramine and to 8.4 minutes on 50 mg. of clomipramine. These estimated times were significantly different from estimated time to ejaculation while on placebo. These findings suggest that low dose clomipramine may be useful in the treatment of premature ejaculation.
