This product is a synthetic nucleoside antiviral drug, which has inhibitory effects on herpes simplex virus type I (HSV-1), type H (HSV-2) and varicella-zoster virus (VZV) in vivo and in vitro. Cell culture results show that this product has the strongest inhibitory effect on HSV-1 virus, followed by HSV-2 and VZV virus. Because this product has affinity for thymidine kinase (TK) encoded by HSV and VZV, it has a highly selective inhibitory effect. This type of viral enzyme converts acyclovir into acyclovir monophosphate, a nucleoside analog. The monophosphate is further converted into diphosphate by guanylate kinase in the cell, and then converted into triphosphate by multiple enzymes in the cell. In vitro, acyclovir triphosphate stops herpes virus DNA replication.

This product is a H2 receptor antagonist of the guanyl thiazole class, which has the characteristics of high affinity for H2 receptors, and has a significant inhibitory effect on gastric acid secretion, and has an inhibitory effect on basal secretion and the increase of gastric acid and pepsin caused by various stimuli. This product does not change the gastric emptying rate, does not interfere with pancreatic function, and has no adverse effects on the cardiovascular system and kidney function. This product is different from cimetidine, but it is similar to ranitidine, that is, long-term high-dose treatment does not cause androgen antagonism side effects such as male breast development, impotence, lack of libido, and female breast pain and galactorrhea, etc. It has no teratogenic, carcinogenic, drug enzyme inhibitory and androgen inhibitory effects.
