Pharmacokinetics When used externally, it is practically not absorbed into the systemic circulation and has no systemic effects. When applying the ointment to the affected area of the skin, a therapeutic concentration of the drug is created in it, which is maintained at a constant level for at least 5 hours.
Pharmacological properties Pharmacodynamics. Purine nucleoside of acyclovir deoxyguanidinide - an analog of the DNA component. Particularly effective against herpes and cold sores. The similarity in the structures of acyclovir and deoxyguanidinide makes it possible for acyclovir to interact with viral enzymes, leading to the cessation of virus replication. After acyclovir enters the herpes-infected cell, the virus is released under the influence of virus-secreted thymidine kinase. Acyclovir-triphosphate has virtually no effect on the replication of host (human) cell DNA.
Acyclovir prevents the development of new elements of the rash during herpes, reduces the possibility of the skin dissemination and visceral complications, accelerates the formation of the crust, relieves pain in the acute phase of drowsiness.
Overdose In areas of prolonged use of the ointment are possible: erythema, peeling, burning sensation, burns, which pass soon after discontinuation of the drug.
