Avana 100 mg is a medication used to treat erectile dysfunction (ED). It contains avanafil, which is a PDE5 inhibitor, similar to sildenafil (found in Viagra), tadalafil (found in Cialis), and vardenafil (found in Levitra). Avanafil works by increasing blood flow to the ****, helping achieve and maintain an erection during ****ual activity. Avanafil works by inhibiting the enzyme PDE5, which leads to increased levels of cyclic GMP (cGMP). This causes the blood vessels in the **** to relax and widen, allowing for increased blood flow and an erection.
