[12][28][70][81][118][144][161][602][603] In instances where substitution therapy is not feasible, concomitant vasoactive therapy with a PDE 5 type inhibitor may promote patient compliance by counteracting ED as an adverse effect. [12][28][70][81][118][144][161][602][603] Efficacy of sildenafil is variable in patients with ED, in part depending on the underlying etiology, severity, and dose employed, but the drug generally appears to be effective in restoring sexual function to an acceptable level in the majority of treated men.

Erectile response to sildenafil is better in patients whose erectile function is less impaired at treatment initiation (e.g., those with some spontaneous successful intercourse, with partial erections, with erections during sleep, or with psychogenic causes). [1][33][105][145] In one flexible-dose study (dosage titration and maintenance up to 100 mg), mean scores for number of successful penetrations returned to normal in a subgroup of patients with psychogenic causes of ED; however, mean scores for maintenance of erections during intercourse in these men were lower than in untreated healthy men. [33][34] In a study in men with ED secondary to radical prostatectomy receiving fixed-dose sildenafil (100 mg), response to therapy was greatest in those who had undergone bilateral-nerve-sparing surgery than in those who had undergone unilateral or non-nerve-sparing procedures. [104][127] Pooled data from various clinical trials indicate that sildenafil improved the erections of 43% of patients with ED secondary to radical prostatectomy compared with 15% of those receiving placebo. patients receiving sildenafil (flexible doses up to 100 mg or fixed doses ranging from 10-100 mg for 12 weeks) for the treatment of ED attributed to complications
