A double-blind trial of clomipramine in premature ejaculation

A double-blind clinical trial was designed to study the effect of clomipramine in 50 patients complaining of rapid ejaculation. Patients were divided into two groups and each group received 2 periods of 6 consecutive weeks' treatment with drug and placebo, so that comparison can be made between drug and placebo within each group and between the two groups. Analysis of collected data showed a significantly higher percentage of satisfactory performances with the drug than with placebo and maintenance of the beneficial effect after the drug was replaced by placebo.
