What is Sildenafil?

Sildenafil citrate powder (bulk) (CAS: 139755-83-2) is a potent and selective PDE5 inhibitor that is primarily used to treat erectile dysfunction and pulmonary arterial hypertension. Sildenafil citrate powder is a safe, fast-acting, and highly effective API that inhibits cGMP-specific phosphodiesterase type 5 (PDE5) activity, allowing nitric oxide (NO) to function more effectively. PDE5 is an enzyme that degrades cGMP. cGMP is a molecule that relaxes muscles and increases blood flow to them. Sildenafil citrate powder increases cGMP levels, which improves blood flow to body tissues by widening blood vessels.
