Merck’s at-home antiviral COVID-19 pill approved by US regulator
Al JazeeraUnited States health regulators have authorised a second antiviral pill against COVID-19, providing another easy-to-use medication to battle the rising tide of Omicron infections. Additionally, Pfizer’s drug was roughly three times more effective in testing than Merck’s, reducing hospitalisation and death by nearly 90 percent among high-risk patients. Merck’s drug is not authorised for use in patients younger than 18 because molnupiravir may affect bone and cartilage growth, the FDA said. “To the extent that there’s an ample supply of Pfizer’s pill, I think it won’t be used,” said Dr Gregory Poland of the Mayo Clinic, referring to the Merck drug. “There would be no reason, given it has less efficacy and a higher risk of side effects.” Dr Nick Kartsonis, Merck’s senior vice president of clinical research, said the company’s scientists are still studying the drug and they hope to eventually get it approved for use in children.
