Contraception is a term often related to birth control and it refers to methods that are used to reduce the likelihood of an egg getting fertilized by a sperm cell. Earlier different methods like coitus interruptus, ingestion of herbs and pessaries were used as contraceptive methods. In modern days different methods of birth control are introduced and it has been proved to be successful though one needs to be cautious about birth control side effects .

Acyclovir brought in a new revolution in antiviral therapy, with its extremely low and selective cytotoxicity. Gertrude B. Elion, the pharmacologist was given the 1988 Nobel Prize in Medicine, for partly developing of Acyclovir.
Acyclovir is different from the previous analogues of nucleoside as it contains only a partial structure of nucleoside where instead of the sugar ring it has an open chain structure. It can be converted into monophosphate which approximately 3000 times more effective in phosphorylation than the thymidine kinase cellular.
