Is tadalafil efficacious in treating ED associated with diabetes mellitus?


Yes. The risk of ED is 4-fold higher in men with  diabetes and approximately 50% of men with  diabetes mellitus have ED [36]. Although the  causes of ED in diabetes mellitus are multifactorial,  at least two major mechanisms are  involved –endothelial dysfunction of the penile  microvasculature and neuropathy of the nerve  fibers that innervate the penis. The efficacy of  tadalafil has been evaluated in 637 men with  Type 1 and Type 2 diabetes (HbA1C [1] 13%) [37].  Treatmentwithtadalafil significantlyimproved  erectile function in men with diabetes regardless  of baseline HbA1C levels or type of diabetes  therapy (insulin, oral agents, or diet alone). The  mean proportion of successful intercourse  attempts in these patients with diabetes was  53% (tadalafil 20 mg) and 49% (tadalafil 10 mg)  compared to 22% of patients receiving placebo  (p < 0.001).
