Abstract
Sixty female and male outpatients with psychosexual dysfunction (sexual aversion/inhibited sexual desire, inhibited sexual excitement, and/or inhibited orgasm) participated in a comparison of the efficacy of bupropion hydrochloride vs placebo. Eight weeks of single-blind treatment with placebo was given at the outset to establish a baseline of sexual ratings/behavior and to eliminate placebo responders. Patients were then assigned randomly to 12 weeks of double-blind treatment with bupropion, 225–450 mglday, or matching placebo. The onset of therapeutic sexual effects was gradual, but by the end of 12 weeks of treatment, significantly greater improvements were noted on the libido and global assessments of sexual functioning in the bupropion group. Sixty-three percent of the bupropion-treated patients reported themselves much or very much improved, compared with 3% for placebo. Changes in the frequency of sexual behavior, however, were much less dramatic and consisted largely of trends toward more sexual activity. To our knowledge, these results represent the first demonstration in a well-controlled clinical trial of an improvement in the psychological aspects of sexual dysfunction due to pharmacologic treatment.
