Avana is a medication primarily used to treat erectile dysfunction (ED) in men. It belongs to the class of drugs called PDE5 inhibitors (phosphodiesterase type 5 inhibitors), which work by increasing blood flow to the penis during sexual arousal. This enhanced blood flow helps men with ED achieve and maintain an erection when sexually stimulated.One of the main advantages of Avanafil is its fast onset of action. It typically starts working within 15-30 minutes of ingestion, allowing for a more spontaneous experience compared to other ED medications like sildenafil (Viagra) or tadalafil (Cialis). In addition, it remains effective for up to 6 hours, providing flexibility for sexual activity within this time frame.
