Pfizer's Paxlovid gains full FDA approval for Covid-19 treatment.

The FDA has granted full approval to Paxlovid, an antiviral medication used to treat mild to moderate Covid-19 in adults at risk of severe infections. Paxlovid is a combination of two medications, nirmatrelvir and ritonavir, taken together as pills for five days within the first five days of a person’s Covid-19 symptoms. In clinical trials, Paxlovid reduced the risk of hospitalization or death by 86% compared with a placebo in people at risk for severe disease. The FDA warns that Paxlovid has interactions with many other types of medications and should only be used to treat Covid-19.
