Answer 1

I believe it is difficult to attain good selective toxicity with antiviral drugs because of the fact that viruses require host cells to replicate themselves.  The Antiviral Drugs have limited selective toxicity because viruses mostly use host cell machinery and therefore there are very unique targets. Most of these drugs block steps that take place within cells, increasing chances for cell toxicity. 

Answer 2

Viral drugs are prescription medicines used for treating viral infections (viruses) rather than bacterial ones. These medications can be only bought with a prescription from your doctor
