Recent Advances in Nanotechnology based Tubercular Chemotherapy

Tuberculosis (TB) is a more prevalent granulomatos bacterial infection, which remains the world’s second most common cause of death due to infections of Mycobacterium tuberculosis (M.Tuberculosis). A number of characteristics of mycobacterium makes there disease chronic and necessitate prolonged treatment. The emergence of multi-drug-resistance (MDR) stains of M.Tuberculosis makes its necessary for the development of effective combinations of either first-line or second-line drugs or discovery of new safe and effective drug molecules and also implements other modalities of treatment. A number of novel carrier-based drug delivery systems incorporating the traditional and newer antitubercular agents have been shown incredible promise to target the site of action, reduce dosing frequency and enhance drug bioavailability with the objective of improving patient compliance. Nanoparticulate system have unique and comparatively more effective drug delivery carriers, including liposomal-mediated drug delivery, polymeric nanoparticles/microparticles, solid lipid nanoparticles, nanosuspensions, nanoemulsions, niosomes, dendrimers, Metal/cyclodextrin inclusion complexes and other nanosystems exploiting the extraordinary properties of matter at the nanoscale. Nanoparticles shown significant improvements in diagnosis, treatment and prevention and provide the flexibility of selecting the invasive and noninvasive route of delivery for chemotherapy of tuberculosis. This manuscript have been made to highlight and overviews the present WHO estimated burden of tuberculosis globally, recent discovery of safe and effective newer anti-tubercular drug moleculesfor MDR and XDR tuberculosis, first and second line anti-tubercular drugs loaded novel nanoparticle carriers for chemotherapy and development of solid lipid nanoparticles as an alternative drug carriers for tubercular chemotherapy.
