Acyclovir is a synthetic nucleoside analogue drug used to treat various kinds of herpes and this includes cold sore (simplex 1) and genital herpes (simplex 2), vericellar (chicken pox), zoster (shingles) and the Epstein- Barr virus. Acyclovir prevents the replication of the virus by interfering with and capitalising on its replication process.
About the Drug
Herpes is a sexually transmitted disease caused by a virus. The virus replicates by taking over healthy cells and causing it to produce more virus DNA. Acyclovir is activated by the herpes virus which then uses the acyclovir nucleoside instead of the normal cell nucleoside for DNA production. The presence of acyclovir within the structure stops the production of the DNA. As virus infected cells absorb acyclovir more than uninfected cells, further virus replication is prevented and more of the acyclovir is activated hence increasing its anti viral function.
How to Take
Acyclovir can be taken regardless of meal times, it comes in various forms: 400 and 800mg tablets, 200mg capsules, 200mg/5ml suspension, 500 and 1000mg powder for intravenous infusion and as a 5% topical cream or ointment.
