1. It has obvious bronchodilator effect; 2. The duration of bronchodilator effect is longer than other similar drugs; 3. It has excellent beta;2-receptor selectivity; 4. It can inhibit the immediate and delayed increase of airway reactivity and has anti-allergic effect; 5. It promotes the movement of respiratory cilia and increases the defense ability of the respiratory tract; 6. It may have an inhibitory effect on the occurrence of exercise-induced asthma.

This product is a non-steroidal anti-inflammatory drug with a strong anti-inflammatory effect, a good effect on inflammatory pain, and a role in promoting uric acid excretion, but a weak antipyretic effect.

Maintains normal functions of epithelial tissues such as skin, conjunctiva, cornea, increases retinal sensitivity, and participates in many oxidation processes in the body, especially the oxidation of unsaturated fatty acids

It is an antioxidant, participates in some metabolic reactions in the body, can fight against the peroxidation of free radicals, protect the skin, enhance ovarian function, and prevent habitual abortion.

Fat-soluble quinone compounds widely exist in organisms. They play an important role in proton translocation and electron transfer in the human respiratory chain. They can be used as activators of cell metabolism and cell respiration. They are also important antioxidants and nonspecific immunopotentiators. They can promote oxidative phosphorylation reactions and protect the structural integrity of biological membranes. They have anti-myocardial ischemia effects, increase cardiac output, reduce peripheral resistance, anti-arrhythmia effects, reduce peripheral vascular resistance, resist the cardiotoxic effects of doxorubicin, and protect the liver. About 75% of patients with coronary heart disease can relieve symptoms such as angina pectoris, chest tightness, palpitations, and dyspnea after taking the drug, and the electrocardiogram can be improved. It is helpful in treating ventricular premature beats. In addition, it can be used as an adjuvant treatment for a variety of diseases.

This product is a broad-spectrum antibacterial agent with bactericidal effect at high concentrations. Many Rickettsia, Mycoplasma, Chlamydia, and Spirochete are sensitive to this product, while Enterococcus is resistant to it. Due to the widespread use of tetracyclines over the years, common clinical pathogens are seriously resistant to tetracyclines, including Gram-positive bacteria such as Staphylococcus and most Enterobacteriaceae. There is cross-resistance between this product and different varieties of tetracyclines. The mechanism of action of this product is that the drug can specifically bind to the A position of the 30S subunit of the bacterial ribosome, inhibit the growth of the peptide chain and affect the synthesis of bacterial proteins.
