Abstract

In an effort to develop an alternative formulation of combination of paclitaxel (PTX) and embelin (EMB) suitable for parenteral administration, PTX-EMB loaded sterically stabilized solid lipid nanoparticles (SLNs) were prepared, characterized and examined for in vitro cytotoxicity. The SLNs, comprising glycerol mono stearate (GMS) as a solid lipid core, Brij 35 used as surfactant and PEGylated phospholipid used as stabilizer, were prepared using a hot homogenization method. Optimized PTX-EMB loaded formulation, the particle sizes of the prepared SLNs were around 300 nm, suggesting that they would be suitable as a parenteral formulation. Transmission electron microscopy showed that the SLNs were homogeneous and spherical in shape. Entrapment efficiency of paclitaxel and embelin was 92.83 ± 2.2%, 83.25 ± 2.4% respectively. An in vitro drug release study were performed in PBS (pH 7.4) for 80 hrs and observed that paclitaxel and embelin released from the PEGylated SLNs was 93.91 ± 4.1 % and 75.63 ± 4.37 % respectively. Furthermore, treatment of the MCF-7 breast cancer cell line with PTX-EMB loaded SLNs yielded cytotoxicities comparable to PTX solution, PTX-EMB mixture solution and PTX loaded PEGylated SLNs. These results collectively suggest that our optimized SLN formulation may have a potential as alternative delivery system for parenteral administration of paclitaxel and embelin.
