It is a sulfonamide diuretic that works by inhibiting the reabsorption of water and electrolytes in the dilution segment of the distal renal tubular cortex. The antihypertensive mechanism may include the following aspects: regulating calcium influx into vascular smooth muscle cells; stimulating the synthesis of prostaglandins PGE2 and prostaglandins PGI2; reducing the hypersensitivity of blood vessels to vasopressors, thereby inhibiting vasoconstriction. This product has little or no effect on cardiac output, heart rate and rhythm when lowering blood pressure. Long-term use of this product rarely affects glomerular filtration rate or renal blood flow. This drug does not affect the metabolism of blood lipids and carbohydrates.

It has an antihistamine effect and can compete with histamine released from tissues for the H1 receptors on effector cells, thereby stopping allergic reactions; it inhibits central nervous system activity and causes sedative and hypnotic effects; it enhances the effects of antitussive drugs; it has anti-vertigo and anti-tremor paralysis effects; it has local anesthetic, antiemetic and anti-M cholinergic effects.

This product is an antibacterial drug. Escherichia coli is mostly sensitive to this product, and some strains of Enterobacteriaceae such as Enterobacter aerogenes, Enterobacter cloacae, Proteus, and Klebsiella are sensitive to this product. Aeruginosa is usually resistant to this product. This product has antibacterial effects on Gram-positive bacteria such as Enterococcus. The antibacterial activity of this product is not affected by pus and tissue decomposition products. It is more active in acidic urine. The antibacterial mechanism is to interfere with the oxidoreductase system in the bacteria, thereby blocking its metabolic process.
