The investigated lipids were either long chain triglycerides (LCT) or medium chain triglycerides (MCT) with different composition, fatty acid chain length, degree of saturation and their absorption pathway to the systemic circulation. Formulations were developed with the purpose of creating thermodynamically stable oil-in-water nano emulsions/suspensions with particle size of 50 nm or less which carry the lipophilic drug and increase water solubility. Following a methodic screening of suitable excipients in-vitro, leading formulations based on sesame oil or MIGLYOL® 812N (Type I LCT/MCT SNEDDS) and cocoa butter or tricaprin (Type II LCT/MCT SNEDDS) were investigated in the freely moving rat model. Results in rat model demonstrated that the effect of each type of lipid on bioavailability of cannabinoids is not straightforwardly anticipated. The differences in the effect of LCT and MCT on absorption was not substantial for Type I formulations, however, more prominent for Type II formulations. This unpredictable behavior in-vivo demonstrates the importance of investigating each vehicle pre-clinically, following the in-vitro development. Cannabis is one of the most chemically complex plants containing a large number of compounds, among which are cannabinoids; the main biologically active constituents of the plant. Delta-9-tetrahydrocannabinol (THC) is known as the main psychoactive cannabinoid. Studies have shown that the effects of THC can be modulated by cannabidiol (CBD), another major cannabinoid which has several beneficial effects of its own. This study aims to look at the effect of different concentrations of THC and CBD separately and in combination on the release of oxygen from eryth
