Tadalafil effective, safe in complete erectile dysfunction
(HealthDay)—In men with complete erectile dysfunction (ED), tadalafil 2.5 and 5 mg once-daily result an in intercourse success rate of 32.4 and 46.4 percent, respectively, according to research published online Oct. 4 in The Journal of Sexual Medicine.
Ridwan Shabsigh, M.D., of the Maimonides Medical Center in New York City, and colleagues conducted a post-hoc, pooled analysis of results from four randomized, double-blind trials evaluating the effects of tadalafil 2.5 or 5 mg compared with placebo in men with complete ED (no successful intercourse attempts at baseline).
After 12 weeks of once-daily treatment with tadalafil, the researchers found that the mean per-patient Sexual Encounter Profile question 3 (SEP3) increased from 0 percent to 32.4 and 46.4 percent with 2.5 and 5 mg tadalafil, respectively. The SEP2 (successful penetration) increased from 21.1 to 48.2 percent and 24.4 to 66.2 percent with 2.5 and 5 mg tadalafil, respectively. The mean International Index of Erectile Function increased significantly with 2.5 and 5 mg tadalafil versus placebo. Compared with placebo, improvements were also noted in intercourse-satisfaction and overall-satisfaction domains. Tadalafil was well tolerated with no increase in adverse events versus placebo.
"Once-daily tadalafil 2.5 or 5 mg significantly enhanced erectile function (versus placebo) across all coprimary and secondary efficacy end points in this analysis, and was generally well tolerated," the authors write.
