Pharmacological properties of Acyclovir ointment

Pharmacodynamics

The antiviral drug is a synthetic analogue of thymidine nucleoside.
In infected cells containing viral thymidine kinase, phosphorylation and conversion to acycpovir monophosphate occurs. Under the influence of guanylyl cyclase acyclpovir monophosphate is converted into diphosphate and under the influence of several cellular enzymes - in triphosphate.
High selectivity of action and low toxicity for humans are due to the lack of the necessary enzyme for the formation of acyclpovir triphosphate in intact cells of the macroorganism.
Acyclovir triphosphate, "embedded" in the DNA synthesized by the virus, blocks the multiplication of the virus. 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.

Pharmacokinetics

When used on intact skin: suction is minimal; not detected in blood and urine. On the affected skin: moderate absorption; in patients with normal renal function, the serum concentration in the serum is up to 0.28 μg / ml, in patients with chronic renal insufficiency (CRF), up to 0.78 μg / ml. It is excreted by the kidneys (up to 9.4% of the daily dose).
