Pharmaceutical oral dose formulation and composition of matter

An apparatus and method for formulating low solubility, low permeability and/or p-glycoprotein efflux transporter substrate drugs or herbal extracts for increased intestinal absorption. The method utilizes a supercritical fluid, such as carbon dioxide to complex a low solubility, low permeability and/or p-glycoprotein efflux transporter substrate drug or herbal extract, the p-glycoprotein inhibitors quercitin and piperine, with a carbohydrate. The result is a micro-emulsion of the drug or herbal extract which has both higher solubility and permeability than if dosed alone; as well as resistance to p-glycoprotein mediated efflux, once absorbed into the intestinal lumen.
