This product is an oxime compound. Its quaternary ammonium group can tend to the cationic site of the phosphorylated cholinesterase that has lost its activity and is combined with the organophosphorus insecticide. Its nucleophilic group can directly combine with the phosphorylated group of cholinesterase and then detach from the cholinesterase together, so that the cholinesterase returns to its original state and regains its activity. It has a significant effect on the nicotine-like symptoms caused by organophosphorus insecticides, but a weak effect on the phytosaminoglycan-like symptoms, and has no significant effect on the symptoms of the central nervous system.

This product is a selective blocker of calcium entering cells, which can reduce venous contraction and prevent excessive calcium ions from entering cells across the membrane under various stimulations and causing cell damage; 1. Inhibit vasoconstriction, and have a lasting inhibitory effect on persistent vasoconstriction caused by vasoconstrictor substances, especially on the basilar artery and internal carotid artery, and its effect is 15 times stronger than that of cephalosporin; 2. Vestibular inhibitory effect, which can increase the blood flow of cochlear radiating arterioles and improve vestibular organ circulation; 3. Anti-epileptic effect, this product can block calcium overload and prevent paroxysmal depolarization, cell discharge, and thus avoid epileptic seizures; 4. Protect the myocardium and significantly reduce ischemic myocardial damage; 5. Flunarizine also has the function of improving renal function and can be used for chronic renal failure; in addition, this product also has anti-histamine effect.

In severe hepatitis or liver dysfunction, the liver's conversion of ammonia to urea is impaired, resulting in increased blood ammonia and encephalopathy symptoms. The intake of glutamate and arginine is beneficial to reduce and eliminate blood ammonia, thereby improving encephalopathy symptoms.

Aminoglycoside antibiotics have antibacterial effects on most Enterobacteriaceae, Pseudomonas aeruginosa, some other Pseudomonas, Acinetobacter, Alcaligenes, meningococci, gonococci, influenza bacilli, Yersinia, Campylobacter fetus, Mycobacterium tuberculosis and some Mycobacterium. The mechanism of action is to act on the 30S subunit of bacterial ribosomes and inhibit bacterial protein synthesis. Combination with semi-synthetic penicillins or cephalosporins can achieve synergistic antibacterial effects.
