Stendra is a medication used to treat erectile dysfunction (ED) [1]. It is a phosphodiesterase type 5 (PDE5) inhibitor that works by increasing blood flow to the penis during sexual stimulation [1][2].
How does Stendra work?
Stendra functions by blocking the PDE5 enzyme, which is responsible for breaking down cyclic guanosine monophosphate (cGMP) [1][2]. By inhibiting PDE5, Stendra allows cGMP to accumulate, leading to the relaxation of smooth muscles in the corpus cavernosum of the penis. This relaxation permits increased blood flow, facilitating an erection in response to sexual arousal [1][2].
When can you take Stendra?
Stendra can be taken as needed, approximately 15 to 30 minutes before sexual activity [1]. It is important to note that sexual stimulation is required for Stendra to be effective [1].
What is the active ingredient in Stendra?
The active ingredient in Stendra is avanafil [1].
How long does Stendra last?
Stendra's effects can last for up to six hours [1].
What are the side effects of Stendra?
Common side effects of Stendra can include headache, flushing, nasal congestion, and back pain [1]. Less common side effects may also occur [1].
Who makes Stendra?

What is the difference between Stendra and other ED medications?
Stendra is a PDE5 inhibitor, similar to medications like Viagra (sildenafil), Cialis (tadalafil), and Levitra (vardenafil) [1][2][4]. However, Stendra is known for its rapid onset of action, typically working within 15-30 minutes, and may have a different side effect profile or efficacy for some individuals [1].
