As a histamine H1 receptor antagonist, this product can counteract the capillary dilation caused by allergic reactions, reduce the permeability of capillaries, and relieve wheezing caused by bronchial smooth muscle contraction. This product has a long-lasting antihistamine effect and also has a significant central inhibitory effect, which can increase the effects of anesthetics, analgesics, hypnotics and local anesthetics. This product is mainly metabolized in the liver.

It has a direct relaxant effect on the smooth muscles of the respiratory tract, and increases the intracellular cAMP content by inhibiting phosphodiesterase; the bronchodilator effect is partly due to the release of endogenous adrenaline and norepinephrine; as a purine receptor blocker, it can counteract the contractile effect of adenine and other substances on the respiratory tract; it enhances the contractility of the diaphragm and improves respiratory function.

Tetracycline antibiotics. This product is a broad-spectrum antibacterial agent. Many Rickettsia, Mycoplasma, Chlamydia, Spirochete, Amoeba and some Plasmodium are also sensitive to this product. Enterococcus is 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 bacteria. There is cross-resistance between different varieties of tetracycline antibiotics.

It has a strong affinity for steroid metabolic enzymes in the liver, hinders the inactivation of cortisol and aldosterone, shows obvious corticosteroid-like effects (such as anti-inflammatory, anti-allergic and protective membrane structure), and has no obvious corticosteroid-like adverse reactions; promotes monochromatic metabolism, reduces the release of ALT and AST; induces γ-IFN and interleukin II, increases NK cell activity and the OKT4/OKT8 ratio and activates the reticuloendothelial system; inhibits the release of histamine from mast cells; inhibits the formation of cell membrane phospholipase A2 (PL-A2) and prostaglandin E2 (PGE2) and granulomatous reactions; inhibits the production and formation of free radicals and lipid peroxides, and reduces the activity of proline hydroxylase; regulates calcium ion channels, protects lysosomal membranes and mitochondria

Glycyrrhizic acid monoamine has a strong affinity for steroid metabolic enzymes in the liver, thereby hindering the inactivation of cortisol and aldosterone. After use, it shows obvious corticosteroid-like effects, such as anti-inflammatory effects, anti-allergic effects, and protective membrane structures; there are no obvious corticosteroid-like adverse reactions. This product can promote monochrome metabolism, reduce the release of ALT and AST; induce γ-IFN and interleukin II, increase NK cell activity and OKT4/OKT8 ratio and activate the reticuloendothelial system; inhibit mast cell release of histamine; inhibit the formation of cell membrane phospholipase A2 (PL-A2) and prostaglandin E2 (PGE2) and granulomatous reactions; inhibit the production and formation of free radicals and lipid peroxides, and reduce the activity of proline hydroxylase; regulate calcium ion channels, protect lysosomal membranes and mitochondria

Taurine is a sulfur-containing amino acid and the main amino acid in the mature retina. This product can promote the growth and development of the retina and relieve ciliary muscle spasm. Taurine competitively binds with reducing sugars in the aqueous humor and vitreous body, preventing the protein in the vitreous body from being saccharified and oxidized.
