It is effective against herpes simplex virus (HSV) type I and II, and secondarily against varicella-zoster virus; it is phosphorylated to acyclovir monophosphate by the virus-encoded thymidine kinase, and further forms acyclovir triphosphate, thereby inhibiting viral DNA polymerase and terminating viral DNA synthesis.

Acyclovir (AZV) is effective against herpes simplex virus (HSV) type I and II, and secondarily against varicella-zoster virus (AZV), but has a weaker effect on Epstein-Barr virus and cytomegalovirus. Acyclovir is effective against herpes simplex virus type I and II and varicella-zoster virus because AZV can be phosphorylated by virus-encoded thymidine kinase (TK) into acyclovir monophosphate, which is then catalyzed by cellular enzymes to form acyclovir diphosphate and triphosphate. Acyclovir triphosphate is a strong inhibitor of herpes simplex virus DNA polymerase. It binds to the enzyme as a substrate of viral DNA polymerase and is incorporated into viral DNA, thereby terminating the synthesis of viral DNA.

Timolol maleate is a non-selective β-adrenergic receptor blocker with no significant endogenous sympathomimetic activity and local anesthetic effect, and no direct inhibitory effect on the myocardium. The exact mechanism of its lowering intraocular pressure is still unclear, but it may be related to reducing aqueous humor production.

This product has a broad-spectrum antibacterial effect, especially high antibacterial activity against aerobic Gram-negative bacilli. It has good antibacterial activity in vitro against the following bacteria: most bacteria of the Enterobacteriaceae family, including Citrobacter, Enterobacter cloacae, Enterobacter aerogenes and other Enterobacteriaceae, Escherichia coli, Klebsiella, Proteus, Salmonella, Shigella, Vibrio, Yersinia, etc. It often also has antibacterial activity against multidrug-resistant bacteria. It has high antibacterial activity against penicillin-resistant Neisseria gonorrhoeae, enzyme-producing Haemophilus influenzae and Moraxella. It has antibacterial effect on most strains of Pseudomonas such as Pseudomonas aeruginosa. This product has antibacterial activity against methicillin-sensitive Staphylococci, and only moderate antibacterial activity against Streptococcus pneumoniae, hemolytic Streptococcus and Enterococcus faecalis. It has good antibacterial activity against Chlamydia trachomatis, Mycoplasma and Legionella.

An acidic mucopolysaccharide, one of the important components of eye tissue, has the functions of promoting corneal water metabolism, improving microcirculation, protecting the cornea and promoting the repair of corneal tissue damage. It can also form a protective film on the surface of the cornea to prevent moisture from escaping, effectively relieving visual fatigue and dry eye symptoms

Chondroitin sulfate is an acidic mucopolysaccharide and one of the important components in eye tissue. It has the functions of promoting corneal water metabolism, improving microcirculation, protecting the cornea and promoting the repair of corneal tissue damage. It can also form a protective film on the surface of the cornea to prevent moisture from escaping, effectively relieving visual fatigue and dry eye symptoms. In addition to its antibacterial and anti-inflammatory effects, taurine also participates in a variety of physiological activities in the eye tissue, promotes metabolism, and improves visual fatigue.
