This product is a methylhydroxyglutaryl coenzyme A (HMG-COA) reductase inhibitor, which inhibits the synthesis of endogenous cholesterol and is a blood lipid regulator. Literature data show that it can reduce the cholesterol (TC) content in the serum, liver, and aorta of hyperlipidemia rabbits, and reduce the levels of very low density lipoprotein cholesterol (VLDL-C) and low density lipoprotein cholesterol (LDL-C).

It has high antibacterial activity against most aerobic Gram-negative bacteria, including Escherichia coli, Klebsiella pneumoniae and Oxytobacter, aerogenes, Cloacae, Proteus, Serratia, Citrobacter, Shigella and other Enterobacteriaceae, as well as influenza bacilli, gonococci, meningococci, etc. It also has good antibacterial effect against Pseudomonas aeruginosa, but has poor antibacterial effect against some Pseudomonas and Acinetobacter species other than Pseudomonas aeruginosa, and has no antibacterial activity against aerobic Gram-positive bacteria such as Staphylococcus and Streptococcus, as well as anaerobic bacteria. Aztreonam exerts its bactericidal effect by binding to penicillin-binding protein 3 (PBP3) on the cell membrane of sensitive aerobic Gram-negative bacteria and interfering with the synthesis of bacterial cell walls.

Selective serotonin reuptake inhibitors work by blocking the reuptake of serotonin in central neurons, have only a weak effect on norepinephrine and dopamine, and have no obvious affinity for multiple receptors.

Antidepressants are highly selective 5-HT reuptake inhibitors that enhance the function of central serotonergic nerves by inhibiting the reuptake of 5-HT by central nervous system neurons. They have little effect on the reuptake of norepinephrine and dopamine, and their effect of inhibiting 5-HT reuptake is mainly exerted by its (S)-enantiomer.
