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.

The main symptom of overdose of this product is vomiting. There is no specific antidote for overdose of this product. Further induction of vomiting and administration of large amounts of fluids are required to ensure that the drug is excreted in the urine. This product can also be removed by dialysis.
