Sildenafil citrate (VIAGRA) improves erectile function in elderly patients with erectile dysfunction: a subgroup analysis
Abstract
BACKGROUND: The prevalence of erectile dysfunction (ED) increases with advancing age, with a particularly high prevalence of ED in elderly patients with diabetes. In the United States it is estimated that approximately 45% of men aged 65 to 69 years have moderate or complete ED. The efficacy and safety of oral sildenafil (VIAGRA) for treating ED in elderly men (aged > or = 65 years or older) were assessed.
METHODS: We analyzed data obtained from five double-blind, placebo-controlled studies of the efficacy and tolerability of oral sildenafil taken as required (but not more than once daily) over a 12-week to 6-month period. Two subgroups were evaluated: (i) elderly patients with ED of broad-spectrum etiology (n = 411), and (ii) elderly patients with ED and diabetes (n = 71). Efficacy was assessed using a global efficacy question, questions 3 and 4 of the International Index of Erectile Function (IIEF). and the five sexual function domains of the IIEF.
RESULTS: All efficacy assessments indicated that sildenafil significantly improved erectile function both in elderly patients with ED of broad-spectrum etiology and in elderly patients with ED and diabetes. The most common adverse events were mild-to-moderate headache, flushing, and dyspepsia. The rates of discontinuation due to adverse events were low and were comparable to the rates with placebo.
CONCLUSIONS: Sildenafil is an efficacious and well-tolerated treatment for ED in elderly men.
