Stendra (Avanafil) General Information

Avanafil is the active ingredient in Stendra, the fastest-acting ED treatment on the market today and recently approved by the FDA. This is a fast-acting ED medication that does wonders in 15 minutes. Avanafil works similar to Viagra, Cialis and Levitra, but it is the fastest acting drug in this category.

Stendra is one of the newest erectile dysfunction treatments available on the market today. Stendra is already making a name for itself as the fastest-acting erectile dysfunction treatment available on the market. Known to be the first on-call treatment, Stendra works almost twice as fast as the leading erectile dysfunction treatment. Stendra is an orally administered phosphodiesterase 5 (PDE5) inhibitor-indicated tablet that is used to temporarily treat erectile dysfunction. Erectile dysfunction is due to a protein in the body that prevents the blood vessels from expanding. Stendra, the active ingredient in generic Stendra, inhibits the activity of protein, allowing the blood vessels to expand to enlarge the penis and facilitate the blood flow. This creates an erection during the time of sexual arousal. Stendra is a revolutionary oral tablet that works in less than 15 minutes (30-60 minutes faster than comparable ED treatments). Why wait for the effect when you can get started whenever you feel like it?
