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.
The general idea behind modern antiviral drug design is to identify viral proteins, or parts of proteins, that can be disabled. [11] [13] These "targets" should generally be as unlike any proteins or parts of proteins in humans as possible, to reduce the likelihood of side effects and toxicity. [8]
Nirmatrelvir/ritonavir is under investigation, so its side effects have yet to be fully evaluated and may not be completely known. [ 19 ] Other side effects of nirmatrelvir/ritonavir may include hypersensitivity reactions , liver toxicity , and development of HIV drug resistance in people with uncontrolled or undiagnosed HIV infection .

This conditional early approval system has previously been used in Japan to accelerate the progression to market of other antiviral drugs targeting COVID-19, including remdesivir and molnupiravir. [13] In a study of 428 patients, viral load was reduced, but symptoms were not significantly reduced. [14]
Ribbon diagram of the protein with the drug shown as sticks. The catalytic residues (His41, Cys145) are shown as yellow sticks. The catalytic residues (His41, Cys145) are shown as yellow sticks. Nirmatrelvir is an antiviral medication developed by Pfizer which acts as an orally active 3C-like protease inhibitor .
Telaprevir (VX-950), marketed under the brand names Incivek and Incivo, is a pharmaceutical drug for the treatment of hepatitis C co-developed by Vertex Pharmaceuticals and Johnson & Johnson. It is a member of a class of antiviral drugs known as protease inhibitors . [ 3 ]
Idoxuridine is an anti-herpesvirus antiviral drug. It is a nucleoside analogue, a modified form of deoxyuridine, similar enough to be incorporated into viral DNA replication, but the iodine atom added to the uracil component blocks base pairing. It is used only topically due to cardiotoxicity. It was synthesized by William Prusoff in the late ...
