Viagra vs Sildenafil Which Is More Effective? - MedExpress

To explain this properly we’ll look at the long answer. Going back to the very start of the drug development process, one drug company will spend anywhere up to £1.2 billion and take up to 12 years to develop one new drug that reaches the market. This money is used in the discovery or design of the drug and clinical trials to prove it has the effect it is supposed to; it is safe to use; and what side effects might occur in using it. In the case of Viagra, it was developed by Pfizer and marketed from 1998. The name Viagra is the brand name, decided upon by Pfizer, while the scientific name of the drug, known as the generic name is sildenafil, this is decided upon by an expert committee. A new drug needs authorisation from a drug licencing authority to confirm its effectiveness, quality and safety before it can be used in the public and this is gained in America from the Food and Drug Administration (FDA) and in UK by the Medicines and Healthcare products Regulatory Authority (MHRA). When the drug is first developed, the company that has developed it receives a patent for the drug that lasts for a set time, for example 20 years. In some respects, such as name, appearance and cost, there are some differences; but in others, such as medicinal content and activity of function, there are virtually none. Since becoming available in 1998, Viagra has become one of the fastest-selling drugs in history, with makers Pfizer reporting that over 23 million men worldwide have used the drug. The 15-year patent on Viagra ran out in 2013, and at this time the drug became available for generic reproduction. Because there have been so many counterfeit versions of the drug sold over the internet over the past two decades, the term ‘Generic Viagra’ has become one generally met with scepticism. But since 2013, Sildenafil has been a legitimate and legal treatment option for ED. To clear up any confusion, we thought we would provide a brief guide to the main differences between the branded version of the drug, Viagra, and its generic counterpart. When a pharmaceutical manufacturer first develops a drug they will, like makers of other types of products or consumables, issue it under a marketing-friendly brand name. In the case of Pfizer, when they released sildenafil for the treatment of ED, the name they gave to their new medicine was Viagra.
