on-demand treatment of premature ejaculation with citalopram: a randomized double-blind study

as the most common male sexual disorder premature ejaculation (pe), also referred to as early ejaculation (ee) or rapid ejaculation (re), affects 30%-40% of sexually active men. despite the limited number of available studies comparing the efficacy of selective serotonin re-uptake inhibitors (ssri) they have been thought to have beneficial effects for the treatment of patients with pe. in the present study, we assessed the efficacy of on-demand use of citalopram, in the treatment of premature ejaculation. a randomized double blind study of fixed dose on-demand use of citalopram was performed in roozbeh psychiatry hospital, tehran university of medical sciences. the sample was consisted of 80 married patients diagnosed with pe according to diagnostic and statistical manual of mental disorders. the patients were randomly assigned to two groups: group 1 consisting of 42 patients received 20mg citalopram, and group 2 consisting of 38 patients received placebo four hours before intercourse for a 4-week treatment course. the effects of drug on the ejaculatory function in each group were assessed by the intravaginal ejaculation latency time (ielt), and the chinese index of premature ejaculation (cipe) before and at the end of treatment course. the mean ielt increased from 66.78±36.94 to 80.85±43.05 seconds in group 1 and from 63.44±33.16 to 65.71±34.26 seconds in group 2 ( p = 0.000). mean cipe score increased 1.14±1.04 and 0.52±0.50 in group 1 and 2 respectively ( p = 0.002). the patients treated with on demand citalopram showed significantly greater improvement in ielt and cipe score compared to the patients receiving placebo. it seems that citalopram may be an effective treatment of premature ejaculation with on-demand usage. however further studies are warranted.
