USPTO Abstract
Many drug therapies could be greatly improved by dosage forms that reside in the stomach for prolonged time and release the drug slowly. In this specification, therefore, an expandable structured dosage form for prolonged release is disclosed. The dosage form generally comprises a three-dimensional structural framework of thin, solid elements. The elements comprise at least a drug, at least a physiological fluid- absorptive excipient, and at least a strength-enhancing excipient. Upon ingestion, the three-dimensional structural framework expands in at least one dimension and forms an expanded semi-solid mass that can be retained in the stomach and release drug over prolonged time.
