It has anti-inflammatory, antipyretic and analgesic effects. Its mechanism of action is to reduce the synthesis of prostaglandins by inhibiting cyclooxygenase. It stops the formation of pain nerve impulses in inflammatory tissues and inhibits inflammatory reactions, including inhibiting the chemotaxis of leukocytes and the release of lysosomal enzymes. As for the antipyretic effect, it acts on the hypothalamic temperature regulation center, causing peripheral vasodilation and sweating, which increases heat dissipation. This central antipyretic effect may also be related to the inhibition of prostaglandin synthesis in the hypothalamus.

Antacids, which neutralize stomach acid and protect the ulcer surface

Inhibit glandular secretion and relieve pain caused by smooth spasm

This product is an analogue of diphenhydramine, which mainly suppresses cough center and relieves cough. It also has a weak antihistamine effect and has no dependence or tolerance. It takes effect 20-30 minutes after taking it and the effect lasts for 3-4 hours.

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.
