give any 4 reasons justify that it is difficult to prepare antivirualmedicines than antibiotics
it is difficult to prepare antiviral medicines because viruses do not use any biochemical pathways to protect themselves .but in case of bacterias, they,use biochemical pathways such as cell wall to protect themselves and antibiotics block such important pathways important for bacteria and as a result bacterias become unable to make cell wall and they die easily.so antivirals are difficult to prepare.
