antiviral agent Antiviral Infectious disease An agent that prevents viral invasion or replication, treats an infection, or thrashes the virus into latency; antivirals may be specific–see below or nonspecific–eg, IFNs, which
stimulate host defenses against viruses, making cells more resistant to viral genes, enhancing cellular immune responses or suppressing viral replication Types Inhibitors of viral DNA replication, transcription, or translation; topical
surfactants; those that reduce viral infectivity by altering the lipid envelope; photodynamic inactivation with dyes which, when activated with UV light, are incorporated into the viral DNA, causing reading errors, IFN and IFN inducers, immune
modulators and vaccines; AAs should not be used prophylactically, as their use selects for drug-resistant strains of virus How to thank TFD for its existence? Tell a friend about us, add a link to this page, add the site to iGoogle, or visit webmaster's page for free fun content. |
