Viagra is a drug used to treat erectile dysfunction among men. It relaxes the muscles in the blood vessels. Additionally, it increases blood flow to particular organs of the body. Historically, Viagra was developed by a group of pharmaceutical chemists in England developing it for hypertension and angina pectoris treatment. Later, it was used to treat erectile dysfunction. On March 27, 1998, the FDA approved Viagra officially as a treatment for erectile dysfunction.

Viagra’s dosage is administered in milligrams and comes in tablet form. Although society was skeptical about these drugs in the past, the present society is gradually accepting them, which has redefined their relevance and acceptability.

What is Viagra?
Viagra is also known as Sildenafil. Its main function in the body is to relax the muscles that are found on the blood vessel walls. This improves the rate of blood circulation to specific parts of the body. With this relaxation and increased blood flow, oxygen is supplied to various body organs, which increases functionality and endurance.

In addition to Viagra, other manufacturers have come out with similar ED medications. Some of the recognizable manufacturers include:

  • Desi Avatars
  • Zydas Cadila
  • Ranbaxy Laboratories

With this kind of competition, Viagra costs have been greatly reduced. This ensures variety and competitive prices.

History of Viagra
Viagra was discovered by accident. The scientists at Pfizer Laboratories are credited with this discovery. These drugs were approved for use by the Food and Drug Administration in 1998. The initial tests were directed towards the possibility of the drug, Sildenafil, used for cardiovascular purposes.

The scientists then noted that their subjects were reluctant to bring the drug back due to the side effects, which were harder and firmer erections that these subjects experienced. Ever since, Sildenafil has become very popular and is being used by millions of people across the globe. Therefore, the negative view that engulfed the idea of Viagra use has slowly been eroded away, and the perception changed to a medical application of the drug.
