Most antivirals target specific viruses, while a broad-spectrum antiviral is effective against a wide range of viruses. [2] Antiviral drugs are a class of antimicrobials, a larger group which also includes antibiotic (also termed antibacterial), antifungal and antiparasitic drugs, [3] or antiviral drugs based on monoclonal antibodies.

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.
BSAs could be divided into experimental and investigational agents, and approved drugs. BSAs work by inhibiting viral proteins (such as polymerases and proteases ) or by targeting host cell factors and processes exploited by different viruses during infection. [ 1 ]
Antisense therapy is a form of treatment that uses antisense oligonucleotides (ASOs) to target messenger RNA (mRNA). ASOs are capable of altering mRNA expression through a variety of mechanisms, including ribonuclease H mediated decay of the pre-mRNA, direct steric blockage, and exon content modulation through splicing site binding on pre-mRNA.

[1] [2] [3] Several antiviral agents are host-directed therapeutics, and simply slow the virus progression rather than kill the virus. Host-directed therapeutics may limit pathogen proliferation, e.g., have bacteriostatic effects. Certain agents also have the ability to reduce bacterial load by enhancing host cell responses even in the absence ...
Clinical trials were halted in 2005 over concerns about the drug's safety. b12 is an antibody against HIV found in some long-term nonprogressors. It has been found to bind to gp120 at the exact region, or epitope, where gp120 binds to CD4. b12 seems to serve as a natural entry inhibitor in some individuals. It is hoped that further study of b12 ...
[10] [11] A virus with Q151M complexed with the other four mutations becomes highly resistant to the above drugs, and is additionally resistant to lamivudine (3TC) and emtricitabine (FTC). [11] [12] The second mechanism is the excision or the hydrolytic removal of the incorporated drug or pyrophosphorolysis. This is a reverse of the polymerase ...
