Acyclovir analogue with the same active substance Zovirax

pharmachologic effect

Antiviral drug, a synthetic analogue of acyclic purine nucleoside, which has a highly selective effect on herpes viruses. In infected cells containing viral thymidine kinase, phosphorylation and conversion to acyclovir monophosphate occurs. Under the influence of guanylyl cyclase acyclovir, monophosphate is converted to diphosphate and under the influence of several cellular enzymes - into triphosphate.

Acyclovirtriphosphate is inserted into the viral DNA chain and blocks its synthesis by competitive inhibition of the viral DNA polymerase. Specificity and very high selectivity of action are also due to its predominant accumulation in cells affected by the herpes virus.

Highly active against Herpes simplex virus type 1 and type 2; a virus that causes varicella and herpes zoster (Varicella zoster); the Epstein-Barr virus. Moderately active against cytomegalovirus.

When herpes prevents the formation of new elements, reduces the likelihood of cutaneous dissemination and visceral complications, accelerates the formation of crusts, reduces pain in the acute phase of herpes zoster.
