The objective of this study was to determine whether the aminoketone antidepressant bupropion has beneficial effects in orgasmic dysfunction. DESIGN: Single-blind, sequential treatment order of three weeks each: placebo, bupropion-SR 150 mg/day, bupropion-SR 300 mg/day. SUBJECTS: Nondepressed women (n = 20) and men (n = 10) having nonphysiologic orgasmic delay or inhibition. MAIN OUTCOME MEASURES: Reported difficulty or delay in achieving orgasm, satisfaction with orgasm and erectile function, and subjective impressions of drug effect. RESULTS: In the women, there were significant improvements relative to baseline (p < .01) on both doses of bupropion-SR in all measured aspects of sexual function, and significant improvements relative to placebo (p < .05) in overall sexual satisfaction on both doses and satisfaction with intensity of orgasm on 150 mg/day (300 mg/day, p = .10). In the men, significant improvements over baseline (p < .01) were observed with both doses in overall sexual satisfaction, ability to achieve an erection, and delay in reaching orgasm/ejaculation; significant improvements relative to placebo (p < .05) were observed in overall sexual satisfaction on both doses, ability to achieve erection on 150 mg/day, and delay in orgasm/ejaculation on 150 mg/day. Seventy percent of subjects reported improvement in libido, arousal, or orgasmic function during bupropion administration. CONCLUSIONS: Bupropion-SR may be a useful agent for treating orgasmic delay and inhibition, and possibly disorders of sexual arousal. The results argue against bupropion's apparent prosexual effect in depressed patients being simply a result of its antidepressant activity.
