Abstract

Abstract : This study aims to prepare spray-dried inhalable powders containing anti-tubercular drugs–loaded HPMC nanoaggregates for sustained delivery of drugs to the lung. Nanoaggregates were prepared by precipitation technique. Results showed that the powders obtained had excellent aerosolization property. High drug encapsulation efficiency was achieved in HPMC nano aggregates, ranging from 60% to 70%. A single pulmonary dose resulted in therapeutic drug concentrations 40% to 60% in the lungs and in other organs (< 5%) for 24 h. From this study, we can conclude that delivering drugs through pulmonary route is advantageous for local action in lungs.
