Proton pump inhibitor. This product is a fat-soluble weakly alkaline drug that is easily concentrated in an acidic environment. After oral administration, it can be specifically distributed in the secretory tubules of gastric mucosal parietal cells. In a high-acid environment, it is converted into an active form of sulfenamide, which irreversibly combines with the sulfhydryl group of H, K-ATPase (also known as proton pump) in the secretory membrane of parietal cells through disulfide bonds to form a complex of sulfenamide and proton pump, thereby inhibiting the activity of the enzyme and blocking the final step of gastric acid secretion. It has a strong and lasting inhibitory effect on gastric acid secretion caused by various reasons.

This product is a prodrug of acyclovir. It is rapidly absorbed after oral administration and quickly converted into acyclovir in the body. Its antiviral effect is exerted by acyclovir. After acyclovir enters the herpes infected cells, it competes with deoxynucleoside for viral thymidine kinase or cellular kinase. The drug is phosphorylated into activated acyclosine triphosphate, which competes with deoxyguanine triphosphate for viral DNA polymerase as a substrate for viral replication, thereby inhibiting viral DNA synthesis and showing antiviral effect. The antiviral activity of this product in vivo is better than that of acyclovir, and the therapeutic index for herpes simplex virus type I and type II is 42.91% and 30.13% higher than that of acyclovir, respectively. It also has a high efficacy against varicella zoster virus and has very low toxicity to mammalian host cells.

It has a significant inhibitory effect on gastric acid secretion and can also inhibit the secretion of pepsin

Minocycline is a semi-synthetic tetracycline antibiotic with antibacterial activity against both Gram-positive and Gram-negative bacteria. Its mechanism of action is to exert antimicrobial effects by inhibiting protein synthesis. This product is more sensitive to sensitive Gram-positive bacteria (such as Staphylococcus aureus, Streptococcus, meningococcus, etc.) and Gram-negative bacteria (such as gonococci, Haemophilus influenzae, etc.); it has a weaker effect on Gram-negative bacilli; it also has a certain effect on microorganisms such as Chlamydia trachomatis and Ureaplasma.

Minocycline is a semi-synthetic tetracycline antibiotic with antibacterial activity against both Gram-positive and Gram-negative bacteria. Its antibacterial spectrum is basically the same as that of tetracyclines. It exerts its antimicrobial effect by inhibiting protein synthesis. It is relatively sensitive to sensitive Gram-positive bacteria (such as Staphylococcus aureus, Streptococcus, and Neisseria meningitidis) and Gram-negative bacteria (such as Neisseria gonorrhoeae and Haemophilus influenzae), and also has a certain effect on microorganisms such as Chlamydia trachomatis and Ureaplasma.
