Antiviral drug - a synthetic thymidine nucleoside analogue. In infected cells containing a viral thymidine kinase, is phosphorylation and conversion to acyclovir monophosphate. Under the influence of guanylate monophosphate is converted to acyclovir diphosphate and under the influence of several cell enzymes - a triphosphate. High selectivity and low toxicity to humans due to a lack of necessary enzymes to form acyclovir triphosphate in intact cells of microorganism. Acyclovir triphosphate, incorporating into "a synthesized virus DNA, blocking replication of the virus. Specificity and very high selective actions are also due to its preferential accumulation in cells infected with herpes virus. Vysokoaktiven against Herpes simplex virus types 1 and 2, the virus that causes chickenpox and shingles (Varicella zoster); Epstein-Barr virus (viruses are listed in ascending order of magnitude of the IPC acyclovir). Moderately active against CMV.

Symptoms: headache, neurological disorders, shortness of breath, nausea, vomiting, diarrhea, renal failure, lethargy, convulsions, coma.

Drug Interactions

When mixing the solutions must be considered alkaline acyclovir for iv injection (pH 11). Enhancement of the effect seen with concomitant administration of immunostimulants. Blockers slow the excretion of tubular secretion of acyclovir, administered iv (an increase of T1 / 2 by 18%).
