Background: Rifampicin (RIF), also known as rifampin, a bactericidal antibiotic having
broad antibacterial activity against various gram-positive and gram-negative bacteria acts by inhibiting
DNA dependent RNA polymerase. RIF has been administered in different dosage forms like tablets,
capsules, injections, oral suspension, powder, etc. for the treatment of several types of bacterial infections,
including tuberculosis, Mycobacterium avium complex, leprosy and Legionnaires’ disease.
Introduction: To ensure the quality, efficacy, safety and effectiveness of RIF drug product, effective
and reliable analytical methods are of utmost importance. To quantify RIF for quality control or pharmacokinetic
purposes, alternative analytical methods have been developed along with the official compendial
Methods: In this review paper, an extensive literature survey was conducted to gather information on
various analytical instrumental methods used so far for RIF.
Results: These methods were high-performance liquid chromatography (42%), hyphenated techniques
(18%), spectroscopy (15%), high-performance thin-layer chromatography or thin-layer chromatography
(7%) and miscellaneous (18%).
Conclusion: All these methods were selective and specific for the RIF analysis.
