What are the key benefits of Spedra?
Spedra has been shown to be effective in clinical trials involving over 1000 men. It was tested on all types of men with erectile dysfunction including men with erectile dysfunction caused by type 1 and type 2 diabetes and in men with erectile dysfunction following bilateral nerve-sparing radical prostatectomy. Spedra was shown to be successful for all types of men at all strengths.
Of those men with ED, the mean percentage of attempts resulting in successful intercourse was approximately 47%, 58%, and 59% for the 50 mg, 100 mg, and 200 mg avanafil groups, respectively, compared to approximately 28% for placebo (a treatment with no active ingredient).
In men with type 1 or type 2 diabetes, the mean percentage of attempts resulting in successful intercourse was approximately 34% and 40% for the 100 mg and 200 mg avanafil groups, respectively, compared to approximately 21% for placebo. In men with ED following bilateral nerve-sparing radical prostatectomy, the mean percentage of attempts resulting in successful intercourse was approximately 23% and 26% for the 100 mg and 200 mg avanafil groups, respectively, compared to approximately 9% for placebo.
