Engineering of Δ9-tetrahydrocannabinol delivery systems based on surface modified-PLGA nanoplatforms

The objective of this work is to develop a nanoplatform that can potentiate the oral administration of Δ9-tetrahidrocannabinol, a highly lipophilic active agent with very promising antiproliferative and antiemetic activities. To that aim, colloidal carriers based on the biodegradable and biocompatib...

Description
Summary:The objective of this work is to develop a nanoplatform that can potentiate the oral administration of Δ9-tetrahidrocannabinol, a highly lipophilic active agent with very promising antiproliferative and antiemetic activities. To that aim, colloidal carriers based on the biodegradable and biocompatible poly(d,l-lactide-co-glycolide) were investigated. Such delivery systems were prepared by nanoprecipitation, and nanoparticle engineering further involved surface modification with a poly(ethylene glycol), chitosan, or poly(ethylene glycol)-chitosan shells to assure the greatest uptake by intestinal cells and to minimize protein adsorption. Characterization of the nanoplatforms included particle geometry (size and shape), electrophoretic properties (surface charge). Δ9-tetrahydrocannabinol vehiculization capabilities (loading and release), blood compatibility, and cellular uptake and cytotoxicity. Results were satisfactorily used to define the optimum engineering conditions to formulate surface modified nanoparticles for the efficient oral administration of Δ9-tetrahydrocannabinol. To the best of our knowledge, this is the first time that biocompatible polymeric nanoparticles have been formulated for Δ9-tetrahydrocannabinoldelivery.
