Avana 100 mg is a medication containing the active ingredient avanafil, which is used to treat erectile dysfunction (ED) in men. Avanafil belongs to a class of drugs called phosphodiesterase type 5 (PDE5) inhibitors, similar to sildenafil (Viagra), tadalafil (Cialis), and vardenafil (Levitra). Avana 100 mg works by increasing blood flow to the penis during sexual stimulation, thereby helping men achieve and maintain an erection. It is typically taken orally, approximately 15 to 30 minutes before anticipated sexual activity, and its effects can last for up to 4 to 6 hours. https://www.flatmeds.com/product/avana-100-mg/
