    Viagra chemical compound


    Sildenafil is a vasoactive agent used to treat erectile dysfunction and reduce symptoms in patients with pulmonary arterial hypertension (PAH). Sildenafil elevates levels of the second messenger, c GMP, by inhibiting its breakdown via phosphodiesterase type 5 (PDE5). PDE5 is found in particularly high concentrations in the corpus cavernosum, erectile tissue of the penis. It is also found in the retina and vascular endothelium. Increased c GMP results in vasodilation which facilitates generation and maintenance of an erection. The vasodilatory effects of sildenafil also help reduce symptoms of PAH. prednisolone liquid for children To treat erectile dysfunction in males, that by suppressing a phosphodiesterase enzyme also suppresses the enzyme's inhibitory effect on the hormone cyclic GMP, and that enables the cyclic GMP produced during sexual arousal to initiate the muscular and vascular changes which produce an erection These example sentences are selected automatically from various online news sources to reflect current usage of the word 'sildenafil.' Views expressed in the examples do not represent the opinion of Merriam-Webster or its editors. Sildenafil inhibits a phosphodiesterase enzyme that degrades cyclic GMP. Higher levels of cyclic GMP in the body promote relaxation of smooth muscle, which allows for increased blood flow to the lungs to lower blood pressure and to the corpus cavernosum to produce an erection during sexual arousal. Sildenafil is marketed under the trademark Viagra to treat erectile dysfunction and under the trademark Revatio to treat pulmonary arterial hypertension.

To better understand its function, consider that an enzyme is a specially folded protein that can speed up a chemical reaction. (For example, the article How Cells Work describes the maltase enzyme.) In the accompanying diagram, you see that maltose is made of two glucose molecules bonded together (1). The maltase enzyme is a protein perfectly shaped to accept a maltose molecule and break the bond (2). A single maltase enzyme can break more than 1,000 maltose bonds per second, and will only accept maltose molecules. PDE5 is an enzyme that accepts c GMP and breaks it down. Pfizer needed a chemical that would gum up PDE5 and keep it from doing its job. The chemical that Pfizer discovered is called sildenafil citrate. It fits right into the PDE5 enzyme and disables it.
