A drug from Pfizer Pharmaceuticals, Viagra enables the bloody flow in the penis to be increased enabling an erection to be maintained for longer - particularly in those that suffer from Erectil Dysfunction. The active component is Sildenafil Citrate - a substance originally developed to improve blood flow to the vessels of the heart. Sildenafil Citrate is absorbed into the bloodstream within 60 minutes of ingestion (usually) and then acts as an inhibitor to an enzyme called phosphodiesterase (PDE5), found primarily in the penis. Inhibiting PDE5 keeps the smooth muscle in the penis relaxed for longer allowing more blood flow into the cavernous tissue, creating an erection.
So there you have it - a snapshot of what Viagra actually does. However, you must also remember that you will still require normal sexual stimulation for an erection to occur, which therefore means that the Viagra is actually enhancing what is a natural process. In this section we will briefly go into the drug, how it was discovered and what effects it can achieve in order to help reduce male impotence. If you require a more medical explanantion, you can either discuss with your local medical practitioner or GP or consult any one of a number of online mdeical papers.
