Antimicrobials and Drug Resistance

Antiviral drugs

Antiviral drugs are the  medication used particularly for treating viral infections.   .Mostly antiviral drug design is to identify targets like  viral proteins, or  its parts, that can be disabled. These "targets" should be as unlike parts of proteins in humans as possible, to reduce the likelihood of various possible side effects. The targets should also be common among different species of virus in the same family or across many strains of a virus, so a single drug  can have broad effectiveness through its mechanism of action. Almost all anti-microbials, including anti-virals, are subject to drug resistance as these pathogenic organism mutate as time travel, resulting less susceptible to the treatment therefore  designing safe and effective antiviral drugs is difficult, because viruses aiways use the host's cells to replicate and increase their count.
