Two Pfizer scientist in Britain, Peter Dunn and Albert Wood, created sildenafil citrate. Sildenafil citrate was originally made to treat high blood pressure. A few years later it was patented as Viagra and clinical trials began. During the trials Viagra had little to no positive effect on high blood pressure or other related conditions like angina. However, clinical volunteers were noted saying days later they experienced an uptick in erections. The research team shifted expectations and ran studies on Viagra and sexual dysfunction. This yielded positive results and in the late 1990s Viagra was dispensed worldwide.
Today Viagra is closely associated with improving impotence as it is the leading pill in the sexual dysfunction market.

How it works
To understand how Viagra works it is important to understand how the body and blood work together. The heart pumps blood all throughout the body through valves. Different areas in the body need different amounts of blood. Essentially, your brain sends signals to nerves, the nerves produce nitric oxide, and the nitric oxide creates an enzyme in nearby cells the create cyclic guanosine monophosphate (cGMP) a muscle relaxer adjacent to arteries. Sometimes this process doesn’t work correctly and blood flow to certain areas decreases.
Viagra helps by building up cGMP in the penis; allowing for greater blood flow. It is important to note that this will only work if the man gets sexually aroused. The brain needs to send the signal down to the pelvic region for Viagra to activate.
