This product is a carbonic anhydrase inhibitor that can inhibit the production of aqueous humor and reduce intraocular pressure. Acetazolamide can inhibit the activity of carbonic anhydrase in the ciliary epithelium, thereby reducing the production of aqueous humor (50% to 60%) and lowering intraocular pressure.

Folic acid is a water-soluble B vitamin composed of pteridine, p-aminobenzoic acid and glutamic acid residues. It is an essential substance for the growth and reproduction of body cells. It participates in many important reactions in the body and the synthesis of nucleic acids and amino acids, promotes cell DNA synthesis, and promotes cell division and maturation.

It has anti-thrombotic effects. Dipyridamole inhibits platelet aggregation, and high concentrations (50 μg/ml) can inhibit platelet release. The mechanism of action may be: (1) Inhibits adenosine uptake by platelets, epithelial cells, and erythrocytes. The inhibitory effect is dose-dependent at therapeutic concentrations (0.5-1.9 μg/dl); (2) Inhibits phosphodiesterase (PDE) in various tissues. The therapeutic concentration inhibits cyclic guanosine monophosphate phosphodiesterase (cGMP-PDE), and the inhibitory effect on cAMP-PDE is weak, thereby enhancing the increase in cGMP concentration caused by endothelial relaxing factor (EDRF); (3) Inhibits the formation of thromboxane A2 (TXA2), which is a strong agonist of platelet activity; (4) Enhances the effect of endogenous PGI2. Dipyridamole has a vasodilatory effect.

Increase the synthesis of GABA and reduce the degradation of GABA, increase the concentration of inhibitory neurotransmitter gamma-aminobutyric acid (GABA), reduce the excitability of neurons and inhibit seizures. In electrophysiological experiments, this product can produce an inhibitory effect on Na channels similar to phenytoin. It is harmful to the liver.
