Avanafil works by inhibiting the action of PDE5, which helps increase blood flow to the penis during sexual stimulation. This increased blood flow is what helps men achieve and maintain an erection. Avana 200 mg should be taken orally with or without food, approximately 15 to 30 minutes before anticipated sexual activity. The effectiveness of the medication may vary from person to person. https://www.flatmeds.com/product/avana-200-mg/
