Form of issue and composition
Eye Ointment Acyclovir is a dosage form for use in ophthalmology. It is available in tubes containing 5 g of ointment.

The active substance of the drug is an antiviral agent. It refers to the synthetic analogue of thymidine nucleoside. Penetrating into an infected cell, acyclovir is converted into an active form, acyclovir triphosphate, by the action of the viral enzyme thymidine kinase. It is embedded in DNA (deoxyribonucleic acid, is a genetic material, contains information in the form of a certain sequence of nucleosides) of the virus and prevents further reading (transcription) of information from it. This blocks further replication (multiplication) of the virus. Since in healthy cells there is no enzyme of thymidine kinase, acyclovir does not adversely affect them. Acyclovir eye ointment is effective mainly against herpes simplex viruses - herpes simplex virus type 1 and 2 (Herpes simplex 1 and 2), the herpes zoster virus (Varicella zoster). The drug to a lesser extent blocks the reproduction of cytomegalovirus (CMV), the Epstein-Barr virus.
After the application of ophthalmic ointment, the active substance is rapidly and almost completely adsorbed by the cells of the stratum corneum and by the ocular (parabulbar) cellulose. It penetrates well into the eyeball, accumulates in the vitreous body of the eye and in the intraocular fluid. In small quantities, acyclovir is absorbed into the systemic bloodstream, penetrates the placenta into the body of the growing fetus during pregnancy and into breast milk during lactation.
