WASHINGTON (AP) — U.S. health regulators on Wednesday authorized the first pill against COVID-19, a Pfizer drug that Americans will be able to take at home to head off the worst effects of the virus.
......
The drug, Paxlovid, is a faster way to treat early COVID-19 infections
......
All of the previously authorized drugs against the disease require an IV or an injection.
......
An antiviral pill from Merck also is expected to soon win authorization. But Pfizer’s drug is all but certain to be the preferred option because of its mild side effects and superior effectiveness, including a nearly 90% reduction in hospitalizations and deaths among patients most likely to get severe disease.
......
The pills from both Pfizer and Merck are expected to be effective against omicron because they don’t target the spike protein where most of the variant’s worrisome mutations reside.
......
Patients will need a positive COVID-19 test to get a prescription. And Paxlovid has only proven effective if given within five days of symptoms appearing. With testing supplies stretched, experts worry it may be unrealistic for patients to self-diagnose, get tested, see a physician and pick up a prescription within that narrow window.
......
Pfizer’s drug is part of a decades-old family of antiviral drugs known as protease inhibitors, which revolutionized the treatment of HIV and hepatitis C. The drugs block a key enzyme which viruses need to multiply in the human body.
The U.S. will pay about US$500 for each course of Pfizer’s treatment, which consists of three pills taken twice a day for five days. Two of the pills are Paxlovid and the third is a different antiviral that helps boost levels of the main drug in the body.
