- Abstract
- PurposeThis study aimed to incorporate ondansetron hydrochloride (ODS), a water-soluble drug into nanostructured lipid carriers (NLCs) to improve the pharmacokinetic properties of the drug.MethodsNLCs were produced by solvent injection method. Various parameters of formulation and process were assessed to enhance the drug incorporation into NLCs. Physicochemical analyses, in vitro drug release, and pharmacokinetic studies were performed.ResultsEntrapment efficiency (EE) of ODS was considerably improved (>90%) by increasing pH of the aqueous phase. The use of an appropriate level of liquid lipid resulted in small, monodispersed NLCs with the enhanced EE and drug loading (DL). The optimized NLCs formulation exhibited particle size of 185.21.9nm, polydispersity index of 0.214 +/- 0.006, EE of 93.2 +/- 0.5%, and DL of 10.43 +/- 0.05% as well as an in vitro sustained-release profile of ODS. Differential scanning calorimetry and X-ray powder diffraction suggested the amorphous state of ODS in the NLCs. The pharmacokinetic study in rats exhibited the sustained-release characteristic of the optimized ODS-loaded NLCs following subcutaneous administration with an extended T-max and mean residence time as well as the enhanced systemic exposure compared to the ODS solution.Conclusions The ODS-loaded NLCs appear potential for prolongation of drug action and reduction in dosing frequency.
