Abstract
Self-emulsifying drug delivery systems are provided to improve dissolution, stability, and bioavailability of drug compounds of dronabinol or other cannabinoids. The drug compound(s) are dissolved in an oily medium (e.g. triglycerides and/or mixed glycerides and/or free fatty acids containing medium and/or long chain saturated, mono-unsaturated, and/or poly-unsaturated free fatty acids) together with at least one surfactant. The surfactant promotes self-emulsification, thereby promoting targeted chylomicron/lipoprotein delivery and optimal bioavailability through the mammalian intestinal tract. A dosage form can optionally include co-solvents, anti-oxidants, viscosity modifying agents, cytochrome P450 metabolic inhibitors, P-GP efflux inhibitors, and amphiphilic/non-amphiphilic solutes to induce semi-solid formation for targeted release rates.
