Millions of the men in the world were suffering from the impotence. The inability to get or sustain the erection is called the impotency or erectile dysfunction. Men all over the world were really feeling ashamed of their failure in the bed and were not having any option. Scientists conducted lot of research to find out the reason behind the impotency. All the research came to the single conclusion that man gets the erection during the sexual activity because of the increased supply of blood in penis. Suddenly, a report published in United States, "First Drug to Treat Impotency Discovered," gave all the impotent men a hope. Thus, the first drug to treat the impotency was discovered and named as Viagra by the manufacturer.

The Viagra that was discovered by the Pfizer was very expensive. Thus, Viagra was out of the reach of the common man. Hence, here the revolution took place and the generic Viagra was introduced by the small companies in United States. Generic Viagra was very cheap as compared to original Viagra. Hence, generic Viagra started gaining the lots of sales in the market, but this made the original manufacturer to lose the hold on market. Thus, the original manufacturer filed the case against generic Viagra manufacturers. Questions like, "Whether generic Viagra is safe?" and "Is generic Viagra FDA approved?" were asked to generic Viagra manufactures. Hence, the generic Viagra manufacturers logged a requisition to the Food and Drug Administration (FDA) in United States for the approval. After checking the standards of the generic Viagra manufacturers, and conducting the clinical trials it was found that generic Viagra is same in effect and properties as the brand-name drug, and treated nearly all the men with erectile dysfunction.

As Food and Drug Administration in United States approved the generic Viagra, the sales of the generic Viagra started booming. Generic Viagra soon became the favorite choice of the customers to treat the erectile dysfunction. The companies manufacturing generic Viagra were selling it very cheap price in comparison to the original Viagra because they wanted to capture the market and still it was affordable to them. The lost costing of generic Viagra was because the manufacturer doesn’t have to invest the money in advertisement, marketing, research, and clinical trials of the generic Viagra because these were already done by the original manufacturer.

Thus because of the low prices generic Viagra captured the market and is ruling the market of the erectile dysfunction drugs. No other erectile dysfunction drug in the market has ever reached the profitability of the generic Viagra that it has made to its manufacturer. Thus on its 10 birthday generic Viagra has become the maximum selling erectile dysfunction drug in pharmacy market.
