Sildenafil mechanism of action - How To Discuss

Sildenafil mechanism of action

What is the mode of action of sildenafil? Sildenafil is a selective cGMP-specific phosphodiesterase (PDE5) inhibitor. ■■■■■■ ■■■■■■■■ involves the relaxation of the erectile tissue, an event mediated by NO and cGMP. The biological effects of cGMP are disrupted by phosphodiesterase enzymes and PDE5 is the major enzyme that metabolizes cGMP in this tissue.

How does sildenafil work to lower blood pressure?

When arteries widen, the opposite happens: blood pressure drops. Sildenafil suppresses PDE5 in pulmonary vascular smooth muscle. This still means that PDE5 cannot break down cGMP and therefore cGMP levels rise. And cGMP helps relax these arteries.

How is sildenafil used to treat erectile dysfunction?

Sildenafil is the generic name for Viagra, which is used to treat erectile dysfunction, and Revatio, which is used to treat pulmonary arterial hypertension. In all cases, sildenafil prevents the enzyme phosphodiesterase5 from breaking down a substance known as cGMP. Sildenafil is thus a phosphodiesterase 5 inhibitor.

The physiological mechanism responsible for ■■■■■■ ■■■■■■■■ involves the release of nitric oxide (NO) into the erectile tissue in response to sexual stimulation.

What is the mechanism of action of sildenafil?

Sildenafil suppresses PDE5 in pulmonary vascular smooth muscle. This still means that PDE5 cannot break down cGMP and therefore cGMP levels rise. And cGMP helps relax these arteries. When you relax, your blood vessels widen and your blood pressure drops.

What is the role of sildenafil in cGMP degradation?

Sildenafil is a potent and selective inhibitor of cGMP-specific phosphodiesterase type 5 (PDE5), which is responsible for the breakdown of cGMP in erectile tissue.

What kind of phosphodiesterase does sildenafil protect?

Sildenafil protects cyclic guanosine monophosphate (cGMP) from degradation by cGMP-specific phosphodiesterase type 5 (PDE5) in erectile tissue.

How does sildenafil inhibit the enzyme PDE5?

This means that the small amount of cGMP they produce breaks down at the same rate and therefore does not have time to accumulate and produce a stable vasodilator effect. Sildenafil works by blocking the PDE5 enzyme and taking its active site.
