Development, optimization and evaluation of anti-tubercular drugs loaded pulmonary solid lipid nanoparticles for management of tuberculosis using Box-Behnken design

The main aim of the study is to develop, optimize and characterize the anti-tubercular drugs loaded solid lipid nanoparticles (SLNs) for pulmonary delivery. In this particular study, the SLNs were developed by modified microemulsification method using Box-Behnken design. The Box-Behnken design shows that the low lipid concentration (2.25%), low surfactant concentration (5 ml), and high homogenization speed (5000 rpm) are the effective factors to be considered for the present study. The optimized formulation shows low particle size (241.6 nm), optimum polydispersity index (0.122), and entrapment efficiency 61.28% for rifampicin, and 66.13% for isoniazid with good release characteristics. The spray drying of resultant SLNs showed good powder flow properties.
