Classification: CPC A  B | IPC A

Claim 0:
1. A pharmaceutical dosage form comprising:
a drug-containing solid having an outer surface and an internal three dimensional structural framework of one or more thin structural elements, said framework contiguous with and terminating at said outer surface;
said thin structural elements having an average thickness in the range of 2.5 μm to 2 mm;
said thin structural elements further comprising at least an active pharmaceutical ingredient, at least an absorptive polymeric excipient being mutually soluble with a physiological fluid, and at least a hydrophilic surface composition;
said thin structural elements further having segments spaced apart from adjoining segments, thereby defining free spaces, wherein a plurality of adjacent free spaces combine across the drug-containing solid to define one or more interconnected free spaces forming an open pore network;
whereby
upon immersion in a physiological fluid said open pore network enables uniform wetting of the structural framework, and the drug-containing solid transitions to a viscous medium, thereby expanding in all dimensions.
