Abstract
This invention relates to an orally administrable, gastroretentive pharmaceutical dosage form which contains at least one pharmaceutically active ingredient and at least one polymeric adjuvant. The adjuvant serves to retain the dosage form in a selected region of the gastrointestinal tract for sufficient time for the pharmaceutically active ingredient to be released and absorbed. Ideally the dosage form will contain two or more pharmaceutically active ingredients which are delivered to different regions of the gastrointestinal tract.
