It forms a protective layer in the intestine to prevent the invasion of pathogens and viruses; stimulates the intestine to secrete antibodies and improves intestinal immunity; selectively kills intestinal pathogens, protects and promotes the growth of beneficial bacteria; regulates the electrolyte and water balance of the intestinal mucosa; promotes the secretion of gastric juice and enhances digestive function.

Rifampicin is a semi-synthetic broad-spectrum antibacterial drug of the rifamycin class, which has antibacterial activity against a variety of pathogenic microorganisms. The drug has a significant bactericidal effect on Mycobacterium tuberculosis and some non-tuberculous mycobacteria (including Mycobacterium leprae, etc.) both inside and outside the host cells. It has a good antibacterial effect on aerobic Gram-positive bacteria, including enzyme-producing strains of Staphylococcus and methicillin-resistant strains, Streptococcus pneumoniae, other Streptococci, Enterococcus, Listeria, Bacillus anthracis, Clostridium perfringens, Corynebacterium diphtheriae, anaerobic cocci, etc. It also has a high degree of antibacterial activity against aerobic Gram-negative bacteria such as Neisseria meningitidis, Haemophilus influenzae, and Neisseria gonorrhoeae. It also has a good effect on Legionella, and has an inhibitory effect on pathogens such as Chlamydia trachomatis, lymphogranuloma venereum, and psittacosis. Bacteria have cross-resistance to rifamycin antibiotics. Rifampicin binds firmly to the beta subunit of DNA-dependent RNA polymerase, inhibiting the synthesis of bacterial RNA and preventing the enzyme from connecting to DNA, thereby blocking the RNA transcription process and stopping the synthesis of DNA and protein.

Participates in the formation of antibodies and collagen in the body, tissue repair (including certain redox effects), metabolism of phenylalanine, tyrosine, and folic acid, utilization of iron and carbohydrates, synthesis of fat and protein, and maintenance of immune function, hydroxylation of 5-hydroxytryptamine, maintenance of vascular integrity, and promotion of absorption of non-heme iron
