PEGylated aceclofenac solid lipid microparticles homolipid-based solidified reverse micellar solutions for drug delivery.

Aceclofenac is a non-steroidal anti-inflammatory drug with poor aqueous solubility and a short half-life resulting in low bioavailability. Aceclofenac-loaded solid lipid microparticles based solidified reverse micellar solution (SLMs-SRMS) for oral drug delivery was investigated to improve the bioavailability and control drug release. Hot homogenization method was adopted to prepare the SLMs using a homolipid irvingia fat and Phospholipon® 90H with or without propylene glycol 6000 (PEGylation) in different ratios and characterized .
