Rifampicin tablets are semi-synthetic broad-spectrum antibacterial drugs of the rifamycin class, which have antibacterial activity against a wide range of pathogenic microorganisms, with significant bactericidal effects against Mycobacterium tuberculosis and some nontuberculous mycobacteria, such as Mycobacterium leprae. Rifampin has highly effective antibacterial activity against a wide range of bacteria, as well as inhibiting pathogens such as Chlamydia trachomatis, lymphogranuloma venereum, and psittacosis. The main efficacy of this drug is in combination with other antituberculosis drugs for the initial treatment or retreatment of tuberculosis, including the treatment of tuberculous meningitis, in combination with other drugs for the treatment of non-tuberculous mycobacterial infections of leprosy, and in combination with vancomycin for severe infections caused by methicillin-resistant staphylococci. The regimen of rifampicin in combination with erythromycin can be used for severe infections of Legionella spp. It can also be used in asymptomatic carriers of Neisseria meningitidis to eliminate Neisseria meningitidis from the nasopharynx, but is not indicated for the treatment of Neisseria meningitidis infections. Finally, we would also like to remind you to use the drug carefully under the guidance of your doctor and pharmacist.
