Abstract
While cannabis is perceived as a relatively safe drug by the public, accumulating clinical data suggest detrimental cardiovascular effects of cannabinoids. Cannabis has been legalized in several countries and jurisdictions recently. Experimental studies specifically targeting cannabinoids' effects on the cerebral vasculature are rare. There is evidence for transient vasoconstrictive effects of cannabinoids in the peripheral and cerebral vasculature in a complex interplay of vasodilation and vasoconstriction. Vasoreactivity to cannabinoids is dependent on the specific molecules, their metabolites and dose, baseline vascular tone, and vessel characteristics as well as experimental conditions and animal species. We systematically review the currently available literature of experimental results in in vivo and in vitro animal studies, examining cannabinoids' effects on circulation and reactive vasodilation or vasoconstriction, with a particular focus on the cerebral vascular bed.

Abstract
AbstractBeta-casein (bCN) micelles were developed as a platform for improved oral bioavailability (BA) of poorly water-soluble drugs. Here we demonstrate a proof-of-concept using the NSAID celecoxib (Cx) loaded into bCN micelles (Cx/bCN). In a crossover pharmacokinetic (PK) study in pigs (n=4), dosed intraduodenally with either the commercial Cx formulation Celebra
