(1) Analgesic effect: It is mainly through inhibiting the synthesis of prostaglandins and other substances that can make pain sensitive to mechanical or chemical stimulation (such as bradykinin, histamine), and is a peripheral analgesic. However, the possibility of central analgesia (possibly acting on the hypothalamus) cannot be ruled out. (2) Anti-inflammatory effect: The exact mechanism is still unclear. It may be due to the fact that this product acts on inflamed tissues and inhibits the synthesis of prostaglandins or other substances that can cause inflammatory reactions (such as histamine) to exert an anti-inflammatory effect. Inhibition of the release of lysosomal enzymes and leukocyte chemotaxis may also be related to it. (3) Antipyretic effect: It may act on the hypothalamic temperature regulation center to cause peripheral vasodilation, increased skin blood flow, sweating, and increased heat dissipation to exert an antipyretic effect. This central effect may be related to the inhibition of prostaglandin synthesis in the hypothalamus. (4) Anti-rheumatic effect: The anti-rheumatic mechanism of this product, in addition to antipyretic and analgesic effects, is mainly anti-inflammatory. (5) Inhibit platelet aggregation: It works by inhibiting platelet cyclooxygenase and reducing the production of prostaglandins.

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 is a central nervous system stimulant that can excite the cerebral cortex, increase sensitivity to the outside world, and constrict cerebral blood vessels, thus enhancing the headache relief effects of the first two drugs.

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

Vitamin B1 is an important component of coenzymes required for sugar metabolism

Vitamin B2 is an important coenzyme component required for tissue respiration

Vitamin B6 is a cofactor for many enzymes and is involved in the metabolism of amino acids and fats.

Nicotinamide is a component of coenzymes I and II, essential for lipid metabolism and oxidation of tissue respiration

Calcium pantothenate is a component of coenzyme A and is involved in the metabolism of sugar, fat, and protein.

This product is a neutral compound of aspirin and acetaminophen bonded by an ester bond. It has antipyretic and analgesic effects, with fewer adverse reactions than aspirin, and is easily tolerated by patients. After oral administration, it is not hydrolyzed in the gastrointestinal tract, is absorbed in the intestine and quickly reaches an effective concentration in the blood, and is characterized by rarely causing gastrointestinal bleeding.

It has both α-receptor and β-receptor stimulating effects. Alpha-receptor stimulating causes vasoconstriction of the skin, mucous membranes, and visceral vessels. β-receptor stimulating causes coronary vasodilation, skeletal muscle, myocardial excitation, increased heart rate, and relaxation of bronchial smooth muscle and gastrointestinal smooth muscle. The effect on blood pressure is dose-related. Common doses increase systolic blood pressure while diastolic blood pressure does not increase or decreases slightly. High doses increase both systolic and diastolic blood pressure.
