Rifalazil is primarily used as an antibiotic, particularly effective against bacterial infections. It is often employed in the treatment of tuberculosis and other mycobacterial infections due to its potent bactericidal properties. Additionally, Rifalazil has shown promise in combating Chlamydia infections, including those that are resistant to other antibiotics. Its ability to penetrate tissues and cells makes it valuable in treating intracellular pathogens. Research is also exploring its potential in addressing chronic inflammatory conditions linked to bacterial persistence.
