Used in the treatment of tuberculosis as an antimicrobial agent, particularly effective against Mycobacterium tuberculosis. It serves as a metabolite of rifapentine and retains significant antibacterial activity, contributing to the overall therapeutic effect in prolonged treatment regimens. Its structure allows for better tissue penetration and longer half-life, supporting intermittent dosing in both active and latent TB management. Also investigated for potential use in combination therapies to reduce drug resistance development.
