(Medscape) – A single pill of the investigational drug molnupiravir taken twice a day for 5 days eliminated SARS-CoV-2 from the nasopharynx of 49 participants. That led Carlos del Rio, MD, distinguished professor of medicine at Emory University in Atlanta, Georgia, to suggest a future in which a drug like molnupiravir could be taken in the first few days of symptoms to prevent severe disease, similar to Tamiflu for influenza.
