After oral administration, a part of it becomes soluble calcium salt under the action of gastric acid, which can increase the concentration of calcium ion in serum, inhibit the thermoregulatory center, reduce the excitability of skeletal muscle and reduce the permeability of blood vessels after being absorbed into the blood through the intestine, so it has antipyretic, spasmolytic and anti-inflammatory effects.
