About Oseltamivir And Its History
It is becoming increasingly well known that oseltamivir is a powerful antiviral drug that impedes the influenza virus from diffusing amongst the cells within a person’s body. This antiviral medication is taken as both a therapeutic treatment and as a prophylactic for infectious influenza A and B viruses. Like the original counterpart zanamivir, oseltamivir falls under the medication class neuraminidase inhibitor. It does its job as a transition-state analogue inhibitor of the flu neuraminidase thus thwarting progeny virions from coming loose from tainted cells.
Oseltamivir also known as generic tamiflu was the initial active neuraminidase inhibitor taken by mouth that was produced for commercial utilization. Generic tamiflu is a prodrug, which metabolizes in the liver to its active metabolite, the free ester of carboxylic acid [GS4071]. It was manufactured by American pharmaceutical company Gilead Sciences but is now marketed by Hoffman – La Roche [or Roche] and goes by the name of Tamiflu. It is widely used in Japan as well as marketed there by the Chugai Pharmaceutical Co.; its ownership is shared 50% with Roche. Oseltamivir is sold and dispensed by prescription only as a universal rule. An estimate by the manufacturer Hoffman – La Roche shows that upwards of 50 million people have had generic tamiflu or oseltamivir as a treatment with a majority 35 million of that amount originating in Japan.
