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.

antiviral agent

an agent that inhibits the REPLICATION of VIRUSES. Very few of these agents are suitable for clinical use, however, mainly because of toxic side effects and/or the occurrence of resistant strains.
