Avana, also known as avanafil, is a medication used to treat erectile dysfunction (ED) in men. It belongs to the class of phosphodiesterase type 5 (PDE5) inhibitors, similar to sildenafil (Viagra), tadalafil (Cialis), and vardenafil (Levitra). Avanafil works by increasing blood flow to the penis when a man is sexually aroused, enabling him to achieve and maintain an erection. Avana is specifically indicated for men diagnosed with erectile dysfunction, which is characterized by the consistent inability to achieve or maintain an erection sufficient for sexual intercourse. If a man's ED is due to physical or psychological factors, avanafil may help improve his erectile function. Avana does not increase sexual desire or arousal on its own. Sexual stimulation and a desire for sexual activity are necessary for the medication to work effectively. Men who have a desire for sexual activity but experience difficulties due to ED may benefit from Avana. Avana's safety and effectiveness depend on an individual's overall health and medical history. It is essential to use Avana under the guidance of a healthcare provider who can assess whether the medication is suitable and safe based on an individual's specific health profile. Avana is typically taken on an as-needed basis, approximately 15 to 30 minutes before anticipated sexual activity. This offers flexibility and spontaneity for men who prefer on-demand treatment for their ED. Men should not use Avana if they have contraindications or interactions with other medications or underlying health conditions. Contraindications may include the use of nitrates or alpha-blockers, which can interact with Avana and lead to potentially dangerous drops in blood pressure.
