Brivudine is used for the treatment of herpes zoster in adult patients. It is taken orally once daily, in contrast to aciclovir, valaciclovir and other antivirals. [1] A study has found that it is more effective than aciclovir, but this has been disputed because of a possible conflict of interest on part of the study authors.
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.
Ribavirin is the only known treatment for a variety of viral hemorrhagic fevers, including Lassa fever, Crimean-Congo hemorrhagic fever, Venezuelan hemorrhagic fever, and Hantavirus infection, although data regarding these infections are scarce and the drug might be effective only in early stages.
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]
Nelfinavir belongs to the class of drugs known as protease inhibitors (PIs) and like other PIs is almost always used in combination with other antiretroviral drugs. Nelfinavir is an orally bioavailable human immunodeficiency virus HIV-1 protease inhibitor (K i = 2 nM) and is widely prescribed in combination with HIV reverse transcriptase ...
Nitazoxanide alone has shown preliminary evidence of efficacy in the treatment of chronic hepatitis B over a one-year course of therapy. [17] Nitazoxanide 500 mg twice daily resulted in a decrease in serum HBV DNA in all of 4 HBeAg-positive patients, with undetectable HBV DNA in 2 of 4 patients, loss of HBeAg in 3 patients, and loss of HBsAg in one patient.

Valganciclovir is eliminated as ganciclovir in the urine, with a half-life of about 4 hours in people with normal kidney function. The mechanism of this drug is activation via a viral protein kinase HCMV UL97 and subsequent phosphorylation by cellular kinases. The phosphotransferase enzyme can likewise activate valganciclovir.
