INTRODUCTION: Erectile dysfunction is increasingly common with advancing age, yet sexual activity and intimacy are important to elderly men. AIM: To assess the efficacy and tolerability of tadalafil in men over the age of 65 years. METHOD: In this multicenter open-label study, 188 men (mean age = 71.6 years) who were over age 65 and did not have diabetes mellitus or clinical depression received tadalafil 20 mg, taken on demand, for up to 12 weeks. MAIN OUTCOME MEASURES: Efficacy was assessed using the International Index of Erectile Function (IIEF) and Sexual Encounter Profile (SEP). Psychosocial outcomes were evaluated using the Psychological and Interpersonal Relationship Scale (PAIRS). RESULTS: Tadalafil treatment significantly improved all domains of the IIEF from baseline, including the erectile function (EF) domain (change = 8.8, end point = 21.6; P < 0.001). Mean per-patient percentage of "yes" responses to SEP questions concerning successful penetration (SEP2; change = 33.5%, end point = 73.5%; P < 0.001) and successful intercourse (SEP3; change = 39.6%, end point = 59.6%; P < 0.001) also improved significantly from baseline. Forty percent of the patients with baseline EF scores < 26 had normal EF (IIEF-EF domain scores > or = 26) at end point, and 81% reported improved erections in the Global Assessment Questionnaire. At least 56% of attempts at sexual intercourse were successfully completed (SEP3) at all time intervals up to 36 hours after tadalafil administration. The patients also experienced significant improvement in both the sexual self-confidence and spontaneity domains of the PAIRS. Tadalafil was well tolerated, with < 5% of the patients discontinuing because of adverse events. CONCLUSION: Tadalafil 20 mg was effective and well tolerated in elderly men with ED.
