Patients who received avanafil 100 mg reported significant improvement in SEP2 and SEP3 in all time intervals measured (from 15 minutes through >6 hours after dosing). However, patients were not excluded based on prior ED therapy. Avanafil has a documented quick onset of action and short duration of effect, and these properties may result in briefer interactions with drugs with similar mechanisms, such as organic nitrates. Avanafil belongs to the same class phosphodiesterase-5 (PDE5) inhibitors as medications like sildenafil (Viagra) and tadalafil (Cialis). There was no significant change in primary end points for the placebo group. Due to these factors, there has been development of newer drugs with fewer side effects. In comparison, the majority of patients receiving sildenafil 50 mg did not experience reduced time to 60% rigidity when compared to placebo.

Among current PDE5 inhibitors, tadalafil has the highest selectivity for PDE1 (<10,000-fold), while vardenafil (1,000-fold) and sildenafil (375-fold) have significantly lower selectivities for this enzyme. After 12 weeks of on-demand use of avanafil, mean increases from baseline in IIEF-EFD score were 8.5 and 8.8 for the 100 mg and 200 mg groups, respectively. Initial dose: 100 mg orally as needed approximately 30 minutes before sexual activity. This study also evaluated the duration of action of avanafil.
