Anti Viral Function:

Like most drugs used to treat infectious pathogens, antivirals are targeted to specific strains of viruses and work in a variety of ways. Most antiviral drugs don't actually kill the virus particles themselves as inhibit their reproduction. Since viruses cannot reproduce without infecting a host cell antiviral drugs have been designed to interfere with the infection process. This interference may be achieved in numerous ways, including blocking the virus from the host cell, preventing the virus from releasing its genetic material once it reaches the nucleus and preventing the virus's genetic data from being spliced into the host cell's DNA. Various highly specific antiviral drugs have also been developed that target the enzymes and proteins that an infected host cell uses to assemble new virus particles and prevent them from functioning correctly. Such drugs must be designed very carefully so that they do not interfere with the metabolism of healthy cells. A final type of antiviral drug targets the virus indirectly, by increasing the efficiency with which the host's immune system can fight the viral infection.
