FDA gives emergency authorization to Pfizer’s COVID-19 pill

COVID-19 sufferers as younger as 12 can now be handled with Paxlovid, an antiviral tablet developed by Pfizer, after the Meals and Drug Administration issued an emergency use authorization on Wednesday. 

“Immediately’s authorization introduces the primary therapy for COVID-19 that’s within the type of a tablet that’s taken orally—a serious step ahead within the combat towards this international pandemic,” stated Dr. Patrizia Cavazzoni, director of the FDA’s Heart for Drug Analysis and Analysis. “This authorization supplies a brand new instrument to fight COVID-19 at an important time within the pandemic as new variants emerge and guarantees to make antiviral therapy extra accessible to sufferers who’re at excessive threat for development to extreme COVID-19.” 

In early November, Pfizer revealed trial outcomes for the brand new oral remedy, saying that it decreased hospitalizations and deaths attributable to COVID-19 by 89 %. Though the outcomes had not undergone peer-review, Paxlovid’s sturdy effectiveness moved an impartial data-monitoring committee to suggest ending the trial early.

However with omicron raging throughout the nation (and all over the world), docs now have one other instrument for treating COVID-19.
