Claim:
An oral osmotic pharmaceutical delivery dosage form comprising: (a) a semipermeable wall; and (b) a single, solid core composition within said wall consisting essentially of: at least one pharmaceutically active agent that has solubility limitations due to inherent hydrophobicity or to high drug load, wherein high drug load means that at least 30% by weight of the dosage form is the at least one active agent, and, homogenously mixed with said pharmaceutically active agent, (1) a non-swelling osmotic agent, and (2) from 1 to 10% by weight of the core of meglumine, as a solubilizer, wherein said wall maintains its integrity during pharmaceutical delivery and has at least one passageway through it, connecting the core of the dosage form with the external environment, wherein the size of the passageway(s) is from 100μ to 1000μ.
