Abstract
One-third of the world's population is infected with tuberculosis (TB), a disease caused by Mycobacterium tuberculosis that survives and replicates within human macrophages. TB is characterized by a long chronic stage of infection and progressive pathology that mainly compromises (90% of cases) the respiratory system (World Health Organization, 2012). The current recommended TB chemotherapy includes: Isoniazid, rifampicin, ethambutol and pyrazinamide. However, patient's non-compliance, several side effects and multi-drug resistant TB infections, often make ineffective the therapy. The present research was aimed to improve the effectiveness of the treatment by a non-conventional therapy and using the respiratory tract as a novel administration route for rifampicin, a first-line anti-TB drug. This approach involved the design of solid lipid microparticles (SLM) as drug delivery system (DDS) showing benefits in terms of biocompatibility, easy of preparation without organic solvents, long-term stability, low cost of materials and procedures as well as easy of scale-up. The study dealt with the formula optimization in order to provide SLM characterized by physicochemical properties proper for the delivery by a dry powder inhaler (DPI) device, for the targeting to alveolar macrophages and for the drug intracellular activity. SLM (~1 μm) loaded with rifampicin were developed by melt emulsification technique using biocompatible lipids and surfactants. They exhibited suitable breathability, negative surface charge promoting the uptake by the alveolar macrophages, good drug loading level, ability to be taken up by macrophage cell lines and antibiotic intracellular activity. Therefore, the lipid microcarrier proposed could be considered a promising DDS in a perspective of an inhaled therapy for the treatment of TB infection.
