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.

This product is an adrenergic agonist. It can selectively stimulate β2-receptors, relax bronchial smooth muscles, inhibit the release of endogenous spasm-inducing substances and edema caused by endogenous mediators, improve the clearance ability of bronchial mucosal ciliary epithelium, and relax uterine smooth muscles.

This product is a calcium channel blocker, and its action is related to the inhibition of calcium ion influx during myocardial and vascular smooth muscle depolarization. This product can effectively dilate the epicardial and subendocardial coronary arteries, relieve spontaneous angina pectoris or angina pectoris caused by coronary artery spasm induced by ergonovine; by slowing down the heart rate and lowering blood pressure, it reduces myocardial oxygen demand, increases exercise tolerance and relieves exertional angina pectoris. This product can relax vascular smooth muscle, reduce peripheral vascular resistance, and lower blood pressure; the extent of its blood pressure reduction is related to the degree of hypertension, and only slightly reduces blood pressure in people with normal blood pressure. This product has a negative inotropic effect and can slow down the conduction of the sinoatrial node and atrioventricular node.

Anticonvulsant, anti-epileptic, anti-neuropathic pain, anti-manic-depressive, improve the symptoms of certain mental illnesses, and prevent central diabetes insipidus. Possible mechanisms include use-dependent blocking of various excitable cell membrane Na channels, inhibition of T-type calcium channels, enhancement of central noradrenergic nerve activity, promotion of antidiuretic hormone (ADH) secretion or increase of effector sensitivity to ADH.
