Abstract
ABSTRACT Background Controlled and targeted drug delivery to treat nonalcoholic fatty liver disease (NAFLD) can benefit from additive attributes of natural formulation ingredients incorporated into the drug delivery vehicles. Methods Lovastatin (LVN) loaded, bile acid (BA) and fatty acid (FA) integrated nanoemulsomes (NES) were formulated by thin layer hydration technique for synergistic and targeted delivery of LVN to treat NAFLD. Organic phase NES was comprised of stearic acid with garlic (GL) and ginger (GR) oils, separately. Ursodeoxycholic acid and linoleic acid were individually incorporated as targeting moieties. Results Stability studies over 90 days showed average NES particle size, surface charge, polydispersity index, and entrapment efficiency values of 270 ± 27.4 nm, −23.8 ± 3.5 mV, 0.2 ± 0.04 and 81.36 ± 3.4%, respectively. Spherical NES were observed under a transmission electron microscope. In-vitro LVN release depicted non-fickian release mechanisms from GL and GR oils-based NES. Ex-vivo permeation of BA/FA integrated NES through isolated rat intestines showed greater flux than non-integrated ones. Conclusion Liver histopathology of experimental rats together with in-vivo lipid profiles and liver function tests illustrated that these NES possess the clinical potential to be promising drug carriers for NAFLD.
