By inhibiting cyclooxygenase, it selectively inhibits the synthesis of prostaglandins in the hypothalamic temperature regulation center, leading to peripheral vasodilation and sweating to achieve an antipyretic effect; by inhibiting the synthesis and release of prostaglandins, it increases the pain threshold and has an analgesic effect. It is a peripheral analgesic, weaker than aspirin, and is only effective for mild and moderate pain. This product has no obvious anti-inflammatory effect.

By inhibiting cyclooxygenase, it selectively inhibits the synthesis of prostaglandins in the hypothalamic temperature regulation center, leading to peripheral vasodilation and sweating to achieve an antipyretic effect; by inhibiting the synthesis and release of prostaglandins, it increases the pain threshold and has an analgesic effect. It is a peripheral analgesic, and its effect is stronger than acetaminophen. It is only effective for mild and moderate pain. This product has no obvious anti-inflammatory effect. (Some information is derived based on acetaminophen)

The specific pharmacological action is not clearly mentioned, but it usually assists in enhancing the antipyretic and analgesic effects.

This product is a glucocorticoid with anti-inflammatory, immunosuppressive, antitoxin and anti-shock effects. (1) Anti-inflammatory effect: It has an effect on inflammation caused by various causes except viruses. Glucocorticoids reduce and prevent tissue response to inflammation, thereby reducing the symptoms of inflammation. They can also inhibit the repair of tissues in the later stages of inflammation and reduce sequelae. (2) Immunosuppressive effect: It prevents or inhibits cell-mediated immune responses, delayed allergic reactions, and reduces the expansion of primary immune responses. (3) Anti-toxic and anti-shock effects: Glucocorticoids can improve the body's tolerance, reduce cell damage, and play a role in protecting the body. It also has the effects of dilating blood vessels, enhancing myocardial contractility, and improving microcirculation.

It can directly stimulate adrenaline receptors, and can also indirectly stimulate adrenaline receptors by prompting adrenaline nerve endings to release norepinephrine. It has a stimulating effect on both alpha and beta receptors. It can dilate bronchi and constrict local blood vessels, and its action time is longer; it strengthens myocardial contractility, increases cardiac output, and makes venous return to the heart sufficient; it has a stronger central nervous system stimulating effect than adrenaline.

It has ① antihistamine effect, which can compete with histamine released from tissues for H1 receptors on effector cells, thereby stopping allergic reactions; ② at the same time, it inhibits central nervous system activity and causes sedative and hypnotic effects; ③ it enhances the effect of antitussive drugs.

1. This product can stimulate DNA synthesis in normal liver cells and promote liver cell regeneration. 2. It has a good protective effect on liver cell damage induced by carbon tetrachloride and promotes the recovery of diseased cells.
