Was Viagra a treatment for angina pectoris? The history of the birth of Viagra is a bit unique, so I would like to tell you about it. The manufacturer, Pfizer, used a component called sildenafil (now the main component of Viagra) to develop a medicine for angina in a laboratory in the United Kingdom. Since it was difficult to achieve good results, we decided to discontinue the phase 1 clinical trial and asked the researchers to return the pre-trial drug, but for some reason many people refused to do so. A detailed study of the cause showed that this study drug improves erectile ability. cheap viagra buy Thus, it was accidentally discovered that sildenafil improved erectile dysfunction in the development of a therapeutic drug for angina pectoris, and the first therapeutic drug in human history was born. On May 6, the American pharmaceutical giant Pfizer announced the launch of an online delivery service for the home-use Viagra (generic name sildenafil) for the treatment of erectile dysfunction (ED). 97% of self-proclaimed online pharmacies are illegal. With increased demand from consumers, the number of online pharmacies selling medicines over the Internet has increased. It is expected that their number will exceed 10 thousand people. Of the total number of pharmacies that legally sell prescription drugs, about 3% of the total, according to a study by the National Federation of Pharmaceutical Affairs, are primarily over-the-counter drugs approved by the US FDA. They seem to be selling drugs they haven’t received. Pfizer explains: Viagra is the best product we make. Carmen Cathison, Managing Director of the National Federation of Pharmaceutical Affairs, said: Although online pharmacies selling original drugs make it easy for people to buy drugs online. According to the company, ED drugs are the most common drugs on the market, and when they were bought from 22 online pharmacies that were clearly at the top of search results for buy Viagra online, they were all original. In the United States, the total amount of counterfeit drug seizures in 2012 is estimated at approximately 83 million dollars.
