PRODUCT INTRODUCTION
description
Nirmatrelvir is an azabicyclohexane that is (1R,5S)-3-azabicyclo[3.1.0]hexane substituted by {(1S)-1-cyano-2-[(3S)-2-oxopyrrolidin-3-yl]ethyl}aminoacyl, 3-methyl-N-(trifluoroacetyl)-L-valinamide, methyl and methyl groups at positions 2S, 3, 6 and 6, respectively. It is the first orally administered inhibitor of SARS-CoV-2 main protease developed by Pfizer and used in combination with ritonavir to treat COVID-19. It has a role as an EC 3.4.22.69 (SARS coronavirus main proteinase) inhibitor and an anticoronaviral agent. It is a nitrile, a member of pyrrolidine-2-ones, a secondary carboxamide, a pyrrolidine carboxamide, a tertiary carboxamide, an organofluorine compound, and an azabicyclohexane. Paxlovid is an antiviral medication used to treat COVID-19 to help decrease symptoms or avoid severe illness in certain patients. Paxlovid works by stopping the virus that causes COVID-19 (SARS-CoV-2) from multiplying. Paxlovid should be taken as soon as possible after diagnosis of COVID-19. Paxlovid contains nirmatrelvir (pink tablets) and ritonavir (white tablets).
