The aim of the study was to improve the bioavailability of atorvastatin calcium (ATC) by formulating polymeric nanoparticles (NPs) with an easy and cost-effective approach. ATC entrapped gelatin nanoparticles (AEGNPs) were prepared by using a simple one-step desolvation method. The formed NPs were characterized by scanning electron microscopy, Fourier transform infrared spectroscopy, and differential scanning calorimetry. Morphological study exhibited a homogenous spherical shape of formulated NPs. FTIR studies revealed the chemical compatibility of the drug with gelatin. The improvement in drug delivery kinetics of AEGNPs could be attributed to amorphization along with the reduction in particle size of ATC. The pharmacokinetic study in Sprague-Dawley rats revealed that the and AUC of AEGNPs in rats were ∼4-fold and ∼11-fold higher than that of pure ATC suspension. The research presented successfully shows that AEGNPs preparation by one-step desolvation, using minimum excipients is a quick, easy and reproducible method. These results suggest that the ATC encapsulated gelatin NP is a promising approach for the oral delivery of ATC, improving the bioavailability of the drug.
