PHARMACHOLOGIC EFFECT
Antiviral drug for topical application in ophthalmology. Highly active against Herpes simplex virus type 1 and 2 and Varicella zoster.
After entering the virus-infected cells, acyclovir is phosphorylated to the active acyclovir triphosphate by the action of viral thymidine kinase. Acyclovir triphosphate acts as a nonspecific inhibitor and substrate for the viral DNA polymerase and prevents the synthesis of viral DNA without damaging the host cells.
PHARMACOKINETICS
After instillation of ophthalmic ointment, acyclovir is rapidly absorbed by the epithelium of the cornea and by eye-eye tissues, as a result of which the concentration of the drug necessary for suppressing the virus is created in the intraocular fluid. Acyclovir is defined in urine in a small concentration, not having a therapeutic value.
INDICATIONS
- keratitis caused by the Herpes simplex virus type 1 and 2.
DOSING MODE
For adults and children, a preparation in the form of an ointment strip 10 mm long should be placed in the lower conjunctival sac. Multiplicity of application 5 times / day with an interval of about 4 hours. Therapy should be continued for another 3 days after the healing.
