Title

Preparation and In-vitro Evaluation of Rifampin-loaded Mesoporous Silica Nanoaggregates by an Experimental Design

Pages

Abstract

 The goal of this research is preparation, optimization and in-vitro evaluation of Rifampinloaded silica nanoparticles in order to use in the pulmonary drug delivery. Nanoparticles are exhaled because of their small size. Preparation of nanoaggregates in a micron-size scale and re-dispersion of them after deposition in the lung is an approach to overcome this problem. We used this approach in our research. Rifampin was selected as a model lipophilic molecule since it was a well-documented and much used anti tuberculosis drug. A half factorial design was used to identify significant parameters of the Spray drying process. The results showed that feed concentration, feed pH and the interaction between feed flow rate and gas atomizer flow rate had statistically significant effects on the particle size of nanoaggregates. The Box-Behnken design was employed to optimize the Spray drying process. Finally, a quadratic equation which explains the relation between independent variables and aerodynamic diameter of nanoaggregates was obtained. Rifampin-loaded Silica nanoaggregates underwent different in-vitro tests including: SEM, Aerosol performance and Drug release. The in-vitro Drug release was investigated with buffer phosphate (pH=7. 4). Regarding the Drug release study, a triphasic pattern of release was observed. The Rifampin-loaded Silica nanoaggregates were capable of releasing 90% drug content after 24 h in combination patterns of release. The prepared Rifampin-loaded nanoaggregates seem to have a potential to be used in a pulmonary drug delivery.
