Avana is a brand name for a medication called Avanafil. Avanafil is a phosphodiesterase type 5 (PDE5) inhibitor used to treat erectile dysfunction (ED) in men. It works by increasing blood flow to the penis during sexual stimulation, which helps men achieve and maintain an erection. Avanafil is similar to other ED medications such as sildenafil (Viagra), tadalafil (Cialis), and vardenafil (Levitra), but it may have a faster onset of action and a shorter duration of effect in some individuals. It typically starts working within 15-30 minutes after taking the medication, with effects lasting for up to 4-6 hours. https://www.flatmeds.com/product/avana-100-mg/
