Clinical Article
Clayton AH et al. – With the exception of orgasmic dysfunction in men without preexisting sexual dysfunction, no significant negative effect on sexual functioning was observed over 12 weeks of treatment with desvenlafaxine.
Methods- The Arizona Sexual Experiences Scale (ASEX) was administered every 4weeks.
- Analysis of covariance was used to compare differences in mean change from baseline ASEX scores between desvenlafaxine and placebo for women and men.
- There were 422 evaluable patients with baseline ASEX scores (desvenlafaxine, N=281; placebo, N=141).
- Among women (desvenlafaxine, N=184; placebo, N=92), baseline scores were 20.0 (5.2) and 20.5(5.3) for desvenlafaxine and placebo, respectively; mean changes at week 12 were -1.93 (0.37) and -1.03 (0.54), respectively (mean difference: 0.90 [–0.38, 2.18]; P=0.169).
- Among men (desvenlafaxine, N=97; placebo, N=49), baseline scores were 16.4 (4.9) and 15.9 (4.8) for desvenlafaxine and placebo, respectively; mean changes at week 12 were -1.13 (0.47) and -1.06 (0.70), respectively (mean difference: 0.07 [–1.59, 1.74]; P=0.932).
- Significantly greater orgasmic dysfunction at week 12 was observed in the subgroup of men without baseline sexual dysfunction treated with desvenlafaxine relative to placebo.
- Conversely, women without baseline sexual dysfunction experienced poorer overall sexual functioning and orgasm satisfaction at week 12 with placebo relative to desvenlafaxine treatment.
- Subgroup analyses of treatment responders and nonresponders found no difference in the proportion of men or women that developed or had resolution of sexual dysfunction in the desvenlafaxine and placebo groups.
