  We report a successful formulation of (CEF) ion paired Solid Lipid Nanoparticle (SLN) with a demonstrated improvement of the intestinal membrane permeability up to 41 folds. Cefepime is a parentally administered fourthgeneration cephalosporin zwitterion. The class 3 BCS drug has high water solubility and low permeability, which result in low oral bioavailability. Our goal is to overcome the low oral bioavailability challenge using double techniques, a molecular alteration ion pairing, and a Nano carrier formulation approaches. The CEF ion pair was prepared by freeze-drying dispersions of an anionic lipid, Sodium Stearate (NaSA), with CEF. Then a combination of Precirol ATO ® 5 and Compritol 888 ATO ® lipids was used in preparing the SLNs using the microemulsion-ultrasonication technique. The enhanced drug permeability was confirmed using an ex vivo rat intestine in a.. View More»
