Generic Avanafil is a medication containing the same active ingredient as Stendra, a brand-name drug used to treat erectile dysfunction (ED). It works by increasing blood flow to the penis, enabling a firmer erection sufficient for sexual activity.
Mechanism of Action
Avanafil belongs to a class of drugs called phosphodiesterase-5 (PDE5) inhibitors. PDE5 enzymes break down a substance called cyclic guanosine monophosphate (cGMP), which plays a key role in penile erection. By inhibiting PDE5, Avanafil allows cGMP levels to rise, resulting in increased blood flow and facilitating erection.
Important Considerations
Avanafil is generally well-tolerated, but potential side effects include headache, flushing, nasal congestion, and back pain. It’s crucial to discuss any pre-existing medical conditions, particularly heart problems, with your doctor before using Avanafil. Also, inform your doctor about all medications you are currently taking, as interactions may occur. Avanafil should not be combined with nitrates, as this can cause a dangerous drop in blood pressure.
