| titleOfInvention | Composition and method for transdermal delivery of cannabidiol (CBD) and Δ9-tetrahydrocannabinol (THC) |
| abstract | A transdermal delivery composition for the delivery to skin and the penetration of the skin includes: (a) a therapeutic effective amount of a cannabinoid mixture, wherein the cannabinoid mixture comprises cannabidiol (CBD) and Δ9-tetrahydrocannabinol (THC) at a weight ratio of about 1:20 to about 20:1; (b) a hydrophilic polymer/hydrophobic polymer adduct in an amount sufficient to hold the cannabinoid composition and provide a sustain release of the cannabinoid mixture after application to skin tissue over a time period of at least 6 hours; (c) a penetrant component in an amount sufficient to assist with a transdermal penetration of the cannabinoid mixture through skin tissue once the composition has been applied to skin tissue; (d) a surfactant component in an amount sufficient to stabilize the polymer adduct and release the cannabinoid mixture from the transdermal delivery composition upon application to skin tissue; and (e) at least about 70 wt. % water. A method of application of a transdermal delivery composition to skin tissue includes applying the transdermal delivery composition to skin tissue and spreading the composition to form a film on the skin tissue. A method for formulating a transdermal delivery composition based on a desired penetration weight ratio of CBD to THC through skin tissue includes selecting a formulation weight ratio of CBD to THC for formulating the composition, wherein the weight ratio is determined by multiplying the desired penetration weight ratio of CBD to THC by a CBD/TCH delivery factor, wherein the CBD/THC delivery factor. |
