- Abstract
- Zaltoprofen is a nonsteroidal anti-inflammatory drug with poor oral bioavailability. S(+)-zaltoprofen (SZPF)-loaded nanostructured lipid carriers (NLCs) were prepared to enhance oral bioavailability. SZPF-loaded NLCs (NLC-SZPF) were prepared using the hot-melting homogenization method and optimized using the Box-Behnken design. The characterization of optimized NLC-SZPF, in vitro release, cytotoxicity, cellular uptake, ex vivo permeability, and pharmacokinetic parameters were evaluated to confirm the advantages of NLC formulation. NLC-SZPF with a diameter of 105.5 +/- 1.2 nm had a high encapsulation efficiency of 99.84 +/- 0.01%. NLC-SZPF showed a sustained-release profile, high biocompatibility, and high permeability across the intestinal tract. The relative bioavailability of NLC-SZPF was 431.3% compared with that of SZPF after oral administration to experimental rats. NLC-SZPF was successfully optimized using experimental designs to enhance the oral bioavailability of SZPF. Hence, NLC-SZPF could be a promising approach to overcome the poor oral bioavailability of SZPF.
