Enhanced oral bioavailability and gastroprotective effect of ibuprofen through mixed polymer–lipid nanoparticles
Abstract
Objectives: The aim of this study was to design and formulate mixed polymer–lipid nanoparticles (PLNs) for the delivery of ibuprofen. Methods: The mixed PLNs were prepared by a single modified emulsification solvent evaporation method. Key findings: Core-shell-shaped mixed PLNs were successfully prepared, with sizes in the nano range (193.3 ± 0.70 to 795.8 ± 0.70 nm) and ζ potential (−26.8 ± 0.45 to −42.8 ± 0.30 mV). Entrapment efficiency ranged from 80.3 to 93.6%. Conclusions: Pharmacokinetic parameters showed great improvement in Cmax and Tmax of ibuprofen from the formulation PLNs8 compared with the respective Brufen® and pure drugs, indicating improvement in bioavailability of the drug.
