A drug combination targeting SARS-CoV-2, Paxlovid, was approved in December 2021 to treat COVID-19. [12] It is a combination of nirmatrelvir , a protease inhibitor targeted to the SARS-CoV-2 3C-like protease , and ritonavir, which inhibits the metabolism of nirmatrelvir, thereby prolonging its effect.

Nirmatrelvir is an antiviral medication developed by Pfizer which acts as an orally active 3C-like protease inhibitor .
SARS-CoV-2 is the seventh known coronavirus to infect people, after 229E, NL63, OC43, HKU1, MERS-CoV, and the original SARS-CoV. [105] Like the SARS-related coronavirus implicated in the 2003 SARS outbreak, SARS‑CoV‑2 is a member of the subgenus Sarbecovirus (beta-CoV lineage B). [106] [107] Coronaviruses undergo frequent recombination. [108]
Scanning electron micrograph of SARS virions. Severe acute respiratory syndrome (SARS) is the disease caused by SARS-CoV-1. It causes an often severe illness and is marked initially by systemic symptoms of muscle pain, headache, and fever, followed in 2–14 days by the onset of respiratory symptoms, [13] mainly cough, dyspnea, and pneumonia.
When used as drugs, the International Nonproprietary Names (INNs) end in -mab. The remaining syllables of the INNs, as well as the column Source, are explained in Nomenclature of monoclonal antibodies. Types of monoclonal antibodies with other structures than naturally occurring antibodies.
This pharmaceutical coding system divides drugs into different groups according to the organ or system on which they act, their therapeutic intent or nature, and the drug's chemical characteristics. Different brands share the same code if they have the same active substance and indications.

SARS-related coronavirus is a member of the genus Betacoronavirus (group 2) and monotypic of the subgenus Sarbecovirus (subgroup B). [13] Sarbecoviruses, unlike embecoviruses or alphacoronaviruses, have only one papain-like proteinase (PLpro) instead of two in the open reading frame ORF1ab. [14]
