DOTS.

  Colloidal Drug Delivery system is an advancing technology expected to bring revolutionary changes in the field of pharma and health sciences including drug delivery, diagnostics and treatment. The advancement in colloidal drug delivery systems helps in preparing newer formulations which become useful for treatment of tuberculosis. Development of Metered dose inhaler (MDT) and Directly Observed Therapy (DOTS) also proves to helpful in treatment of tuberculosis. Various colloidal drug delivery systems liposomes, niosomes, nanoparticles and microparticles proves to be a successful tool for tuberculosis treatment. One of the preparations like microemulsions results in theimprovement of bioavailability of the drugs. Similarly corticosteroids also found to be an interesting tool here because corticosteroids reduced the risk of pleural thickening in tuberculosis patients. These various colloidal drug delivery systems minimize the problems of conventional therapy like poor penetration, drug resistance, systemic toxicity and also main the improved drug delivery. This article describes the applications of various formulations along with their future aspects in treatment of tuberculosis.
