Acyclovir capsules
Function and Efficacy
This product is an antiviral drug. In vitro, it has inhibitory effects on herpes simplex virus, herpes zoster virus, cytomegalovirus, etc. After entering the cells infected with herpes virus, this product competes with deoxynucleoside for viral thymidine kinase or cellular kinase, and the drug is phosphorylated into activated acyclovir triphosphate, which then inhibits viral replication in two ways: ① Interfering with viral DNA polymerase to inhibit viral replication; ② Under the action of DNA polymerase, it binds to the growing DNA chain, causing the extension of the DNA chain to be interrupted. This product has a special affinity for viruses, but has low toxicity to mammalian host cells. There are reports of carcinogenicity in in vitro cell transformation assays, but no evidence of carcinogenicity has been found in animal experiments. Some animal experiments show that high concentrations of drugs can cause mutations, but there is no evidence of chromosomal changes. Carcinogenicity of this product
