								| Description | Molnupiravir (EIDD-2801, MK-4482) is the isopropylester prodrug of [N4-hydroxycytidine].[A193014,A193026] With improved oral bioavailability in non human primates, it is hydrolyzed _in vivo_, and distributes into tissues where it becomes the active 5’-triphosphate form.[A193026] The active drug incorporates into the genome of RNA viruses, leading to an accumulation of mutations known as viral error catastrophe.[A193029] Recent studies have shown molnupiravir inhibits replication of human and bat coronaviruses, including SARS-CoV-2, in mice and human airway epithelial cells.[A193014] A [remdesivir] resistant mutant mouse hepatitis virus has also been shown to have increased sensitivity to N4-hydroxycytidine.[A193014]
Molnupiravir was granted approval by the UK's Medicines and Health products Regulatory Agency (MHRA) on 4 November 2021.[L39050] | 
							
								| Indications and Usage | [N4-hydroxycytidine] and its prodrug molnupiravir are being studied for its activity against a number of viral infections including influenza, MERS-CoV, and SARS-CoV-2.[A193014, A193029]
Molnupiravir is approved in the UK for reducing the risk of hospitalization and death in mild to moderate COVID-19 cases for patients at increased risk of severe disease (eg. with obesity, diabetes mellitus, heart disease, or are over 60 years old).[L39050,L39055] |
