    摘要: This invention pertains to the enhanced delivery of orally administered pharmaceutical agents and methods, dosage forms and devices thereof. In particular, the invention is directed to methods including providing a low solubility drug having a pKa between about 6 and about 9; dissolving the low solubility drug in an aqueous solution, wherein a pH of the aqueous solution is less than about 6.0; dissolving a hydrophilic polymer in the aqueous solution, wherein the weight ratio of the hydrophilic polymer to the low solubility drug is less than or equal to about 0.15; lyophilizing the aqueous solution to obtain a lyophilized powder. Also disclosed are drug formulations made according to the method, and dosage forms that include the drug formulations.
