Avanafil is a medication used to treat erectile dysfunction in men. It belongs to the class of phosphodiesterase type 5 (PDE5) inhibitors, which work by increasing blood flow to the penis during sexual stimulation, helping to achieve and maintain an erection.
Avanafil is taken orally, usually 15-30 minutes before sexual activity, and has a rapid onset of action. Compared to other similar medications, avanafil is known for its fast effect and good tolerability. The duration of its effect may vary but generally lasts for several hours.
Side effects may include headache, facial flushing, nasal congestion, or dizziness. It is important not to use avanafil with nitrate-containing medications, as this can cause a dangerous drop in blood pressure. Avanafil should be used as directed by a healthcare provider.
