This product has anti-inflammatory, antipyretic and analgesic effects. Its mechanism of action is to reduce the synthesis of prostaglandins by inhibiting cyclooxygenase. It stops the formation of pain nerve impulses in inflammatory tissues and inhibits inflammatory reactions, including inhibiting the chemotaxis of leukocytes and the release of lysosomal enzymes. As for the antipyretic effect, it acts on the hypothalamic temperature regulation center, causing peripheral vasodilation and sweating, which increases heat dissipation. This central antipyretic effect may also be related to the inhibition of prostaglandin synthesis in the hypothalamus.

After entering the body, this product can combine with poisons containing hydroxyl or carboxyl groups to form low-toxic or non-toxic combinations that are excreted in the urine, protecting the liver and detoxifying. In addition, glucuronic acid can increase the content of liver glycogen and reduce fat reserves.

It is an oxidized derivative of adrenaline and has no adrenaline-mimetic effect, so it does not affect blood pressure and heart rate, but it can enhance the resistance of capillaries to damage, stabilize the acidic mucopolysaccharides in blood vessels and surrounding tissues, reduce the permeability of capillaries, and enhance the retraction effect of damaged capillary ends, making it difficult for blood clots to fall off the tube wall, thereby shortening the hemostasis time, but it does not affect the coagulation process.

This product is a synthetic antibacterial anti-tuberculosis drug. It has strong activity against bacteria in the growth and reproduction stage, and has almost no effect on bacteria in the dormant stage. It has high antibacterial activity against various types of mycobacteria. There is no cross-resistance between Mycobacterium tuberculosis and this product and other drugs. It may inhibit the metabolism of sensitive bacteria, inhibit RNA synthesis, and interfere with the protein metabolism of Mycobacterium tuberculosis, thereby causing bacterial death. In large doses, it can cause cleft palate, brain exposure, and spinal deformity in mouse experiments; it can cause mild cervical deformity in rat experiments; it can cause cyclops, short limbs, and cleft palate in rabbit experiments.

This product is an analogue of diphenhydramine, which mainly suppresses cough center and relieves cough. It also has a weak antihistamine effect and has no dependence or tolerance. It takes effect 20-30 minutes after taking it and the effect lasts for 3-4 hours.
