This product is a blood lipid regulating drug of clofibric acid derivatives. It reduces blood low-density lipoprotein, cholesterol and triglycerides by inhibiting the production of very low-density lipoprotein and triglycerides and increasing their catabolism at the same time; it also increases the production of apolipoprotein A1 and A11, thereby increasing high-density lipoprotein. This product also has the effect of reducing blood uric acid in normal people and patients with hyperuricemia. Animal experiments have shown that fenofibrate is teratogenic and carcinogenic.

Iron is a component of hemoglobin in red blood cells. When iron is deficient, the amount of hemoglobin synthesized by red blood cells decreases, causing the red blood cells to become smaller and their oxygen-carrying capacity to decrease, resulting in iron-deficiency anemia. Oral administration of this product can supplement iron and correct iron-deficiency anemia.

A selective β1-adrenergic receptor blocker with no membrane stabilizing effect and endogenous sympathomimetic activity. However, it does not inhibit the bronchodilator effect of isoproterenol. Its mechanism of lowering blood pressure and reducing myocardial oxygen consumption is the same as that of propranolol. Large-scale clinical trials have confirmed that atenolol can reduce the mortality rate of acute myocardial infarction within 0 to 7 days. The therapeutic dose has no significant inhibition on myocardial contractility.

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.
