It has analgesic, anti-inflammatory and antipyretic effects. Its mechanism of action is to reduce the synthesis of prostaglandins by inhibiting cyclooxygenase, thereby alleviating tissue congestion and swelling caused by prostaglandins and reducing the sensitivity of peripheral nerve pain. It has an antipyretic effect through the hypothalamic temperature regulation center.

Analgesic, anti-inflammatory, antipyretic, anti-rheumatic, inhibiting platelet aggregation

As a histamine H1 receptor antagonist, this product can counteract capillary dilation caused by allergic reactions, reduce capillary permeability, and relieve wheezing caused by bronchial smooth muscle contraction. This product has a long-lasting antihistamine effect and also has a significant central inhibitory effect, which can increase the effects of anesthetics, analgesics, hypnotics and local anesthetics. This product is mainly metabolized in the liver.

By blocking the membrane transport of calcium ions in myocardial and vascular smooth muscle, inhibiting the influx of calcium ions into cells, it causes a decrease in myocardial contractility and vasodilation. Animal experiments have shown that by reducing myocardial contractility and peripheral vascular resistance, myocardial oxygen consumption is reduced; by dilating coronary vessels and developing collateral circulation, the oxygen supply to myocardial ischemic sites is increased; by inhibiting the consumption of high-energy phosphate compounds, the ability to resist hypoxia is enhanced.
