It can relax the sphincter of Oddi, has strong antispasmodic and analgesic effects, and can also gently and continuously promote bile secretion, strengthen gallbladder contraction and antibacterial effects, has obvious choleretic effects, is conducive to the discharge of stones, and has a certain stone discharge effect on common bile duct stones. Some patients with elevated alanine aminotransferase will return to normal after taking the medicine as the inflammation is eliminated. This product has low toxicity, and the acute toxicity LD50 of mice is 5375mg/kg.

It can cause blood vessels to contract, reduce capillary permeability, enhance platelet aggregation and adhesion, promote platelets to release coagulation active substances, shorten coagulation time, and achieve hemostatic effect.

Calcium channel blockers inhibit the transmembrane calcium ion influx of myocardial and vascular smooth muscle without changing the blood calcium concentration and have a high degree of vascular selectivity; they dilate coronary vascular smooth muscle, increase the exercise tolerance of patients with chronic stable angina pectoris, and reduce the frequency of angina attacks; they reduce the body's peripheral vascular resistance, lower blood pressure, and can lower the systolic and diastolic blood pressure of patients with mild to moderate hypertension; they increase the cardiac ejection fraction and cardiac output, with little change in left ventricular end-diastolic pressure; they temporarily increase urinary sodium excretion; they block slow calcium channels without affecting fast sodium channels; no mutagenic and reproductive toxic effects have been found.

A mild peripheral vasodilator with the pharmacological effects of niacin and inositol and lipid-lowering effects; the vasodilatory effect is mild and long-lasting, without the side effects of niacin flushing and stomach discomfort; it selectively dilates blood vessels in diseased areas and areas sensitive to cold stimulation; it has the effects of dissolving blood clots, anticoagulation, anti-fatty liver, and reducing capillary fragility.

Tetracycline antibiotics, broad-spectrum antibacterial agents, have bactericidal effects at high concentrations. It is sensitive to Rickettsia, Mycoplasma, Chlamydia, atypical mycobacteria, and spirochetes. It is more effective against Gram-positive bacteria than Gram-negative bacteria, but Enterococcus is resistant to it. Others such as Actinomycetes, Bacillus anthracis, Listeria monocytogenes, Clostridium, Nocardia, Vibrio, Brucella, Campylobacter, and Yersinia are sensitive to it. It has certain antibacterial activity against Neisseria gonorrhoeae, but penicillin-resistant Neisseria gonorrhoeae is also resistant to it. Common clinical pathogens are seriously resistant to this product, including Gram-positive bacteria such as Staphylococcus and most Gram-negative bacilli.
