This product is an anti-thyroid drug. Its mechanism of action is to inhibit thyroid peroxidase, thereby hindering the oxidation of iodide absorbed into the thyroid gland and the coupling of tyrosine, and hindering the synthesis of thyroxine (T4) and triiodothyronine (T3). Animal experiments have observed that it can inhibit the synthesis of antibodies by B lymphocytes, reduce the level of thyroid stimulating antibodies in the blood circulation, and restore the function of inhibitory T cells to normal.

This product has anti-inflammatory, antipyretic and analgesic effects. Its mechanism of action is to reduce the synthesis of prostaglandins by inhibiting cyclooxygenase. It stops the formation of pain nerve impulses in inflammatory tissues and inhibits inflammatory reactions, including inhibiting the chemotaxis of leukocytes and the release of lysosomal enzymes. As for the antipyretic effect, it acts on the hypothalamic temperature regulation center, causing peripheral vasodilation and sweating, which increases heat dissipation. This central antipyretic effect may also be related to the inhibition of prostaglandin synthesis in the hypothalamus.

Vitamin B2 is a component of coenzyme, involved in the metabolism of sugar, protein, and fat, maintaining normal visual function and promoting growth.

This product has a broad-spectrum antimicrobial effect in vitro, including aerobic Gram-negative and Gram-positive bacteria, anaerobes, Rickettsia, spirochetes and Chlamydia. It has bactericidal effects on the following bacteria: Haemophilus influenzae, Streptococcus pneumoniae and Neisseria meningitidis. It only has antibacterial effects on the following bacteria: Staphylococcus aureus, Streptococcus pyogenes, Streptococcus viridans, Group B hemolytic Streptococcus, Escherichia coli, Klebsiella pneumoniae, Proteus mirabilis, Salmonella typhi, Salmonella paratyphi, Shigella, Bacteroides fragilis and other anaerobic bacteria. The following bacteria are usually resistant to chloramphenicol: Pseudomonas aeruginosa, Acinetobacter, Enterobacter, Serratia marcescens, indole-positive Proteus, methicillin-resistant Staphylococcus and Enterococcus. This product is an antibacterial agent. Chloramphenicol is fat-soluble and its mechanism of action is to diffuse into bacterial cells and reversibly bind to the 50S subunit of bacterial ribosomes, thereby hindering the growth of peptide chains (possibly due to the inhibition of transpeptidase), thereby inhibiting the formation of peptide chains and preventing protein synthesis.
