It has a strong antitussive effect, and has antihistamine, smooth muscle spasm relief, anti-inflammatory and local anesthetic effects. The antitussive effect usually appears 30-60 minutes after taking the medicine, and the effect lasts for 4-6 hours or longer.

Vitamin D2 is an essential substance for human growth and development, especially for fetuses and infants. Vitamin D2 participates in calcium and phosphorus metabolism, promotes their absorption, and plays an important role in bone formation.

Calcium plays an important role in the formation of human bones, reconstruction of bone tissue, muscle contraction, nerve transmission, coagulation mechanism and maintaining capillary permeability.

This product is a second-generation sulfonylurea antidiabetic drug, which is effective for most patients with type 2 diabetes. It can reduce fasting and postprandial blood sugar and reduce glycosylated hemoglobin (HbAlc) by 1% to 2%. The main function of this type of drug is to stimulate pancreatic b cells to secrete insulin, but the prerequisite is that pancreatic b cells still have a certain function of synthesizing and secreting insulin. Its mechanism is to specifically bind to the sulfonylurea receptor on the b cell membrane, thereby closing the K channel, causing changes in membrane potential, opening the Ca2 channel, and increasing intracytoplasmic Ca2, which promotes insulin secretion. In addition, there are extra-pancreatic effects, including improving the insulin resistance of peripheral tissues (such as liver, muscle, and fat).

This product belongs to the class Ic (i.e., directly acting on the cell membrane) antiarrhythmic drug. The experimental results of isolated animal myocardium indicate that 0.5-1ug/min can reduce the depolarization effect during contraction, thereby prolonging conduction, slightly prolonging the duration of action potential and the effective refractory period, and can increase the threshold potential of myocardial cells, significantly reducing the spontaneous excitability of the myocardium. It acts on both the atrium and ventricle (mainly affecting the Purkinje fibers, with a smaller effect on the myocardium), and also on the formation and conduction of excitement. Clinical data show that the therapeutic dose (300mg orally and 30mg intravenously) can reduce the irritability of the myocardium, the effect is long-lasting, PQ and QRS are increased, and the effective refractory period of the atrium and atrioventricular node is prolonged. It has an antagonistic effect on various types of experimental arrhythmias.
