Inhibitor: Stendra (Avanafil) is a Phosphodiesterase type-5 (PDE5) inhibitor.
Mechanism of Action:
Stendra is a PDE5 inhibitor. It functions by:
- Increasing blood flow: Stendra widens the blood vessels and smooth muscles of the penis, allowing more blood to pass through.
- Erectile enhancement: The increased blood supply assists men in attaining and sustaining an erection upon sexual arousal.
- Avanafil inhibits phosphodiesterase-5, preventing the degradation of cGMP.
- The increased levels of cGMP cause vasodilation, resulting in an increased blood flow in the penis.
- Avanafil inhibits the cGMP-specific phosphodiesterase type 5 (PDE5) which is responsible for the degradation of cGMP in the corpus cavernosum located around the penis.
- The increased levels of cGMP cause vasodilation, resulting in an increased blood flow in the penis.
- Elevated cGMP level relaxes the smooth muscles and dilate blood vessels in penile region.
- Sexual arousal results in the local release of nitric oxide, which in turn stimulates the enzyme guanylate cyclase to produce cGMP.
