Abstract: A pharmaceutical composition, a combination product including the composition and a method of manufacturing the composition. The composition includes a particulate complex of API bound with a crosslinked polysaccharide micro sponge. The combination product includes a dosage form of the particulate complex within a container. The amount of the particulate complex is selected to provide a defined dose of the API. The formulation may be heated within the container by a vaporizer device, vaporizing the API and dissociating the API from the micro sponge as vapour, which passes through apertures in the container facilitating administration of the API by inhalation of the vapour. The apertures are sized to facilitate passage of the vapour but prevent passage the particulate complex. The API may be hydrophobic such as phytocannabinoids or hydrophilic such as nicotine. The pharmaceutical composition may be manufactured by driving binding of the API to the micro sponge in solution.

Abstract: A method of selectively recovering a hydrophobic target substance. The method is applied to a solution of the target substance in a hydrophobic solvent. An insoluble polysaccharide is combined with the solution, the solution is passed over the insoluble polysaccharide or otherwise exposed to the insoluble polysaccharide. A hydrophilic solvent, which is less hydrophobic than the hydrophobic solvent, is combined with the solution or combined with the hydrophobic target substance and the insoluble polysaccharide after evaporation of the hydrophobic solvent to facilitate binding of the insoluble polysaccharide with the target substance rather than remaining in solution in the hydrophobic solvent. The cyclic polysaccharide is isolated from the solution. A dissociation solvent is combined with the cyclic polysaccharide for solubilizing the target substance from the cyclic polysaccharide and recovering the target substance.
