Abstract:


Aim: This study is focused on preparing rifampicin loaded bovine serum albumin nanoparticles (RIF BSA NPs) suitable for intravenous application using systematic quality by design (QbD) approach. Background: Rifampicin is one of the first line drugs used for tuberculosis therapy. The therapy lasts for a long time. Thus, there is a need to develop sustained release formulation of rifampicin for intravenous application.

Objectives: The main objective of this study is optimizing particle size and entrapment efficiency of rifampicin loaded bovine serum albumin nanoparticles (RIF BSA NPs) and making it suitable for intravenous application using QbD approach.

Methods: Quality target product profile was defined along with critical quality attributes (CQAs) for the formulation. 32 factorial design was used for achieving the predetermined values of CQAs, i.e., mean particle size <200 nm and percent entrapment efficiency>50%. Incubation time of drug with colloidal albumin solution and ratio of rifampicin: albumin, were selected as independent variables. Check point analysis was performed to confirm the suitability of regression model for optimization.

Results: The optimized RIF BSA NPs were characterized by FTIR, DSC, 1H NMR techniques. The NPs observed by transmission electron microscopy were spherical in shape. The rifampicin release could be sustained for 72 hours from BSA NPs matrix. RIF BSA NPs dispersion was stable at 5 ± 3°C for 72 hours. Non-toxicity of nanoparticles to RAW 264.7 cell line was proved by MTT assay.

Conclusion: Development of RIF BSA NPs with desired quality attributes was possible by implementing QbD approach. The optimized formulation suitable for intravenous application can potentially improve the therapeutic benefits of rifampicin.
