Zinc is an important component of many enzymes in the body and has the functions of promoting growth and development, improving taste, etc. When it is deficient, growth stagnation, reproductive inability, difficulty in wound healing, body weakness, conjunctivitis, stomatitis, glossitis, lack of appetite, chronic diarrhea, loss of taste, and neurological symptoms may occur. Zinc is particularly important for the growth and development of children.

This product can directly penetrate the cell membrane into the body cells, activate pyruvate oxidase, so that cells in a low-energy and hypoxic state can continue to metabolize smoothly, and participate in the energy metabolism and protein synthesis of the human body.

This product is a medium-acting sulfonamide. It has antibacterial effects on non-enzyme-producing Staphylococcus aureus, Streptococcus pyogenes, Streptococcus pneumoniae, Escherichia coli, Klebsiella, Salmonella, Shigella and other Enterobacteriaceae, gonococci, meningococci, Haemophilus influenzae. In addition, it also has antimicrobial activity against Chlamydia trachomatis, Nocardia asteroides, Plasmodium and Toxoplasma in vitro. The antibacterial activity of this product is the same as that of sulfamethoxazole. However, in recent years, bacterial resistance to this product has increased, especially Streptococcus, Neisseria and Enterobacteriaceae. Sulfonamides are broad-spectrum antibacterial agents. This product is similar in structure to para-aminobenzoic acid (PABA), and can compete with PABA on dihydrofolate synthase in bacteria, thereby preventing PABA from being used as a raw material to synthesize folic acid required by bacteria, reducing the amount of metabolically active tetrahydrofolate, which is an essential substance for bacteria to synthesize purine, thymidine and deoxyribonucleic acid (DNA), thereby inhibiting the growth and reproduction of bacteria.

This product mainly acts on α receptors, directly stimulating α receptors. Its effect is weaker than that of norepinephrine but more persistent. Its cardiovascular effect is similar to that of norepinephrine. It can constrict blood vessels, continuously increase systolic and diastolic blood pressure, and enhance myocardial contractility. The cardiac output of normal people does not change much, but it can increase the cardiac output of patients with shock. The excitement of heart rate is not very significant, rarely causes arrhythmia, and has no central nervous system excitation effect. Because its pressor effect is reliable and lasts for a long time, it rarely causes reactions such as palpitations or decreased urine volume. When administered continuously, because this product indirectly replaces the transmitter in the adrenergic nerve vesicles, it can reduce the transmitter and weaken the intrinsic effect. Therefore, it cannot be stopped suddenly to avoid rebound hypotension.
