Avanafil is used to treat male sexual function problems (impotence or erectile dysfunction-ED). In combination with sexual stimulation, avanafil works by increasing blood flow to the penis to help a man get and keep an erection. Erection occurs 20 minutes after a 200 mg dose of avanafil. Absorption is delayed by food. So the tablets may take longer to work if taken after a meal.
