Avana 100 mg contains avanafil, a PDE5 inhibitor similar to sildenafil (Viagra), tadalafil (Cialis), and vardenafil (Levitra). It works by increasing blood flow to the penis during sexual stimulation, facilitating the achievement and maintenance of an erection. Avana 100 mg is typically taken orally, as needed, approximately 15 to 30 minutes before sexual activity. It can be taken with or without food. Avanafil is known for its rapid onset of action compared to other PDE5 inhibitors. https://www.flatmeds.com/product/avana-100-mg/
