It is a peripheral analgesic. Its mechanism of action is to inhibit the synthesis and release of prostaglandins (PGE1) in the hypothalamic temperature regulation center, thereby causing peripheral vasodilation and sweating to achieve an antipyretic effect. At the same time, it can inhibit the effects of PGE1, bradykinin and histamine, increase the pain threshold and produce analgesic effect.

It can inhibit the synthesis and release of prostaglandins in the hypothalamus, restore the normal responsiveness of the receptor neurons in the body temperature regulation center and have an antipyretic effect; at the same time, it also has an analgesic effect by inhibiting the synthesis of prostaglandins, etc., and can inhibit the synthesis and release of prostaglandins in local inflammatory tissues, stabilize lysosomal enzymes, and affect the phagocytic function of macrophages to have an anti-inflammatory effect.

It is a central nervous system stimulant that can excite the cerebral cortex, increase sensitivity to the outside world, constrict cerebral blood vessels, and enhance the effect of the first two drugs in relieving headaches.

It has a strong histamine H1 receptor blocking effect, can alleviate other respiratory symptoms caused by allergies, and also has a mild inhibitory effect on the central nervous system.

This product is a non-steroidal anti-inflammatory analgesic. It has analgesic, antipyretic and anti-inflammatory effects, and its anti-inflammatory effect is relatively strong. Acute toxicity test results: the oral LD50 of rats is 780mg/kg, and the oral LD50 of mice is 630mg/kg.

Effective for intestinal infections caused by Shigella dysenteriae and Escherichia coli

Analgesic effect: It may have a central analgesic effect by inhibiting the synthesis of prostaglandins and other sensitive substances; Anti-inflammatory effect: It may inhibit the synthesis of prostaglandins or related inflammatory substances; Antipyretic effect: It may increase heat dissipation by acting on the hypothalamic temperature regulation center; Anti-rheumatic effect: In addition to antipyretic and analgesic effects, it mainly has anti-inflammatory effects; Inhibition of platelet aggregation: It reduces prostaglandin production by inhibiting platelet cyclooxygenase.

This product is a fluoroquinolone antibacterial drug with a broad-spectrum antibacterial effect, especially high antibacterial activity against aerobic Gram-negative bacteria. It has good antibacterial activity against the following bacteria in vitro: most bacteria of the Enterobacteriaceae family, including Citrobacter, Enterobacter cloacae, Enterobacter aerogenes and other Enterobacter species, Escherichia coli, Klebsiella, Proteus, Salmonella, Shigella, Vibrio, Yersinia, etc. Norfloxacin also has antibacterial activity against multi-drug resistant bacteria in vitro. It also has good antibacterial effects on penicillin-resistant Neisseria gonorrhoeae, Haemophilus influenzae and Moraxella catarrhalis. Norfloxacin is a bactericide that acts on the A subunit of bacterial DNA helicase, inhibiting DNA synthesis and replication, leading to bacterial death.
