Stendra (avanafil) works by inhibiting phosphodiesterase type 5 (PDE5), an enzyme that breaks down cyclic guanosine monophosphate (cGMP). Increased cGMP levels relax the smooth muscles in the penis, allowing for increased blood flow and facilitating an erection.
Clinical trials demonstrate Stendra’s rapid onset of action. Many men experience effects within 15-30 minutes of taking it. Its relatively short half-life means its effects are typically shorter-lasting than other PDE5 inhibitors.
Efficacy varies depending on individual factors, such as overall health and the specific cause of erectile dysfunction. Studies show Stendra successfully improves erectile function in a significant percentage of men with erectile dysfunction. Specific success rates differ based on dosage and study design.

Stendra’s side effects are generally mild and transient. Common ones include headache, flushing, nasal congestion, and back pain. Serious side effects are rare but require immediate medical attention.
Always follow your doctor’s instructions for dosage and usage. Do not exceed the recommended dose.
