Molnupiravir (development codes MK-4482 and EIDD-2801) is an experimental antiviral drug which is orally active (can be taken orally) and was developed for the treatment of influenza. It is a prodrug of the synthetic nucleoside derivative N4-hydroxycytidine, and exerts its antiviral action through introduction of copying errors during viral RNA replication.[1][2] Activity has also been demonstrated against coronaviruses including SARSMERS and SARS-CoV-2.[3]

The drug was developed at Emory University by the university’s drug innovation company, Drug Innovation Ventures at Emory (DRIVE). It was then acquired by Miami-based company Ridgeback Biotherapeutics, who later partnered with Merck & Co. to develop the drug further.
