It inhibits the synthesis and release of prostaglandins in the hypothalamus, restores the normal responsiveness of the sensory neurons in the temperature regulation center, and has an antipyretic effect; it has an analgesic effect by inhibiting the synthesis of prostaglandins, etc.; it inhibits the synthesis and release of prostaglandins in the local tissue of inflammation, stabilizes lysosomal enzymes, and affects the phagocytic function of phagocytes, thus playing an anti-inflammatory role

It inhibits the synthesis and release of prostaglandins in the hypothalamus, restores the normal responsiveness of the receptor neurons in the temperature regulation center, and has an antipyretic effect; it has an analgesic effect by inhibiting the synthesis of prostaglandins, etc.

It excites the cerebral cortex, increases sensitivity to the outside world, constricts cerebral blood vessels, and enhances the effect of aminopyrine and phenacetin in relieving headaches

It has sedative, hypnotic and anticonvulsant effects, can enhance the analgesic effect of aminopyrine and phenacetin, and prevent convulsions caused by fever

It relaxes vascular smooth muscle, activates guanylate cyclase by releasing nitric oxide (NO), increases cyclic guanosine monophosphate (cGMP) in smooth muscle cells, thereby dilating peripheral arteries and veins, reducing the amount of blood returning to the heart, lowering left ventricular end-diastolic pressure and pulmonary capillary wedge pressure (preload), reducing peripheral vascular resistance, systolic arterial pressure and mean arterial pressure (afterload), dilating coronary arteries to increase coronary perfusion, and ultimately reducing myocardial oxygen consumption and increasing oxygen supply.

This product is the earliest sulfonamide antibiotic used for intestinal infections.

This product is a broad-spectrum antibacterial agent with bactericidal effect at high concentrations. It specifically binds to the A position of the bacterial ribosome 30S subunit, preventing the aminoacyl-tRNA from linking at this position, thereby inhibiting the growth of the peptide chain and affecting the synthesis of bacterial proteins. It has antibacterial effects on Streptococcus pneumoniae, hemolytic Streptococcus, Streptococcus viridans and some Staphylococci, Clostridium perfringens, Bacillus anthracis, Yersinia pestis, Corynebacterium diphtheriae, Clostridium tetani, Brucella, Haemophilus influenzae, Campylobacter, Vibrio cholerae, etc. It also has inhibitory effects on Rickettsia, Mycoplasma, Chlamydia, Spirochete, and some protozoa. However, most Enterobacteriaceae such as Escherichia coli, Klebsiella, Salmonella, Shigella, etc. are resistant, and there is cross-resistance between the same species.
