Tetracycline antibiotics. This product is a broad-spectrum antibacterial agent. Many Rickettsia, Mycoplasma, Chlamydia, spirochetes, amoebas and some malarial parasites are also sensitive to this product. Enterococci are resistant to it. Others such as Actinomycetes, Bacillus anthracis, Listeria monocytogenes, Clostridium, Nocardia, Vibrio, Brucella, Campylobacter, Yersinia, etc. are sensitive to this product. This product has certain antibacterial activity against gonococci and meningococci, but penicillin-resistant gonococci are also resistant to oxytetracycline. Due to the widespread use of tetracyclines over the years, common clinical pathogens have serious resistance to oxytetracycline, including Gram-positive bacteria such as Staphylococcus and most Gram-negative bacilli. There is cross-resistance between different varieties of tetracycline antibiotics.

1. Outstanding antibacterial effect: It has obvious antibacterial effect on Staphylococcus, Candida (fungus), Asian B virus, acid-fast bacilli and various Gram-positive and negative bacteria. 2. It has obvious inhibitory effect on Gram-positive and negative bacteria. 3. Enhance immune function: Strengthen the body's defense function (enhance the phagocytic ability of white blood cells). 4. It has obvious antibacterial effect on Helicobacter pylori.

It is a peripheral analgesic. Its mechanism of action is to inhibit the synthesis and release of prostaglandins (PGE1) in the hypothalamic temperature regulation center, thereby causing peripheral vasodilation and sweating to achieve an antipyretic effect. At the same time, it can inhibit the effects of PGE1, bradykinin and histamine, increase the pain threshold and produce analgesic effect.

It can inhibit the synthesis and release of prostaglandins in the hypothalamus, restore the normal responsiveness of the sensory neurons in the temperature regulation center, and have an antipyretic effect; at the same time, it can also have an analgesic effect by inhibiting the synthesis of prostaglandins, etc. It can also inhibit the synthesis and release of prostaglandins in the local tissue of inflammation, stabilize lysosomal enzymes, and affect the phagocytic function of phagocytes to have an anti-inflammatory effect.

It is a central nervous system stimulant that can excite the cerebral cortex, increase sensitivity to the outside world, constrict cerebral blood vessels, and enhance the effect of the first two drugs in relieving headaches.

It has a strong histamine H1 receptor blocking effect, can alleviate other respiratory symptoms caused by allergies, and also has a mild inhibitory effect on the central nervous system.
