This product is a new type of non-narcotic analgesic, with mild antipyretic and muscle relaxant effects. Its chemical structure belongs to cyclized o-methylbenzylamine. Therefore, it does not have the characteristics of non-steroidal anti-inflammatory drugs, nor is it an opioid receptor agonist. It is effective for moderate and severe pain. An intramuscular injection of 20 mg of this product is equivalent to the effect of 12 mg of morphine. It has a mild respiratory depressant effect. It has no depressant effect on the circulatory system. There is no tolerance and dependence.

Blood pressure reduction: The exact mechanism of blood pressure reduction is unknown. It mainly dilates arterioles, with little effect on veins, reducing peripheral vascular resistance, increasing heart rate, and increasing stroke volume and cardiac output. Long-term use can increase renin secretion, aldosterone, and water and sodium retention, which reduces the effect. Heart failure: This product increases cardiac output and reduces vascular resistance and afterload.

It has highly selective antibacterial effects on all types of Mycobacterium tuberculosis. It is the synthetic antibacterial drug with the strongest bactericidal effect among current anti-tuberculosis drugs, and has almost no effect on other bacteria. It has a strong effect on Mycobacterium tuberculosis in the growth and reproduction stage, but a weaker and slower effect on the dormant stage. Its mechanism of action may be to inhibit the synthesis of mycolic acid in sensitive bacteria and cause the cell wall to rupture.
