It can inhibit the body's prostaglandin synthase, reduce prostaglandin synthesis and produce good antipyretic and analgesic effects

It is a central nervous system stimulant that constricts cerebral blood vessels. It can be used with acetaminophen to reduce headaches caused by colds.

It is an antihistamine that can further relieve the discomfort caused by colds and has a sedative effect.

It can eliminate nasopharyngeal mucosal congestion, relieve nasal congestion symptoms, relax bronchial smooth muscles, and has a strong antitussive and antiasthmatic effect.

Inhibits the influx of Na+ and Ca2+ ions across cell membranes, and stabilizes the cell membranes of excitable cells such as bronchial smooth muscle and inflammatory cells

Blocks bronchial smooth muscle choline M receptors and histamine H1 receptors, relaxes bronchial smooth muscle, inhibits the release of allergic mediators, and reduces capillary permeability

Stimulate beta 2 receptors, promote the release of norepinephrine from nerve endings, enhance diaphragmatic contraction, and help improve respiratory function; stimulate alpha receptors on airway vascular smooth muscle, constrict airway blood vessels, and inhibit congestion and edema

This product is a compound preparation mainly based on phenytoin sodium and contains a variety of drugs with different mechanisms of action. Its main mechanism of action is: inhibiting the influx of Na+ and Ca2+ ions across the cell membrane, stabilizing the cell membrane of excitable cells such as bronchial smooth muscle and inflammatory cells; ephedrine hydrochloride stimulates beta;2 receptors, promotes the release of norepinephrine from nerve endings, enhances the contraction of the diaphragm, and is beneficial to improving respiratory function. Belladonna fluid extract and chlorpheniramine maleate can block the choline M receptors and histamine H1 receptors of bronchial smooth muscle, respectively, and relax bronchial smooth muscle. In addition, this product also has the effects of stimulating alpha; receptors on airway vascular smooth muscle, contracting airway blood vessels, inhibiting congestion and edema; inhibiting the release of allergic mediators, reducing capillary permeability; reducing viscosity by changing mucin synthesis; promoting airway ciliary movement, and enhancing diaphragmatic contraction. There is a good synergistic effect between the components of this product. Experiments have shown that this product has a good effect on histamine and acetylcholine. It has a significant antiasthmatic effect on asthma caused by antigens, and has a significant antitussive effect on various experimental coughs. This product also has a certain expectorant effect.

Reduce viscosity by changing mucin synthesis; promote airway ciliary movement and enhance diaphragmatic contractility

Reduce viscosity by changing mucin synthesis; promote airway ciliary movement and enhance diaphragmatic contractility

Blocks bronchial smooth muscle cholinergic M receptors, relaxes bronchial smooth muscle

It can inhibit the synthesis of prostaglandins and has antipyretic and analgesic effects

It is an antihistamine that can relieve symptoms such as runny nose, nasal congestion, and sneezing.

Antipyretic and sedative effects

This product is a new type of non-narcotic analgesic, with mild antipyretic and muscle relaxant effects. It is effective for moderate and severe pain. An intramuscular injection of 20 mg of this product is equivalent to the effect of 12 mg of morphine. It has a mild respiratory depressant effect. It has no depressant effect on the circulatory system. There is no tolerance and dependence.

It has central and peripheral antitussive effects, and its antitussive effect is about 1/3 of that of codeine. In addition to having a direct inhibitory effect on the respiratory center of the medulla oblongata, it also has a mild atropine-like effect. It can relax spasmodic bronchial smooth muscles and reduce airway resistance.
