Viagra

Description

A Viagra tablet was first developed by Pfizer, a pharmaceutical company, in the 1990s and was approved by the U.S. Food and Drug Administration (FDA) in 1998. It has since become one of the most commonly prescribed medications for ED, and is available in various doses and formulations.

How does it work?

Viagra UK Wales contains sildenafil citrate that works by blocking the action of an enzyme called phosphodiesterase type 5 (PDE5), which is responsible for breaking down a chemical called cyclic guanosine monophosphate (cGMP).

During sexual stimulation, the release of nitric oxide in the male sexual organ causes an increase in cGMP levels, which relaxes the smooth muscle in the blood vessels of the male sexual organ and allows blood to flow into it, resulting in an erection.

However, PDE5 can break down cGMP and prevent it from doing its job. Viagra online England works by inhibiting PDE5 and increasing the levels of cGMP, allowing for improved blood flow to the male sexual organ and a stronger, longer-lasting erection.
