摘要：PURPOSE:An inexpensive prolonged release pharmaceutical, containing Plantago seeds containing a water-swellable mucilagions substance, and capable of forming a mucilaginous gel matrix and releasing a chemical component constantly at a givae ratio, and easily preparable. CONSTITUTION:A prolonged release pharmaceutical containing Plantago seeds of the genus Plantago of the family Plantaginacea. The amount of the Plantago seeds to be incorporated is 1-50%, preferably 10-30%. The Plantago seeds are well known as a purgative, but the action of forming mucilaginous gel matrix is novelly utilized to produce the aimed prolonged release pharmaceutical as a medicine. The gelation of the mucilaginous substance by hydration swells and expands the whole pharmaceutical and forms a matrix membrane. Thus, the release of the chemical component is controlled. The raw material Plantago seeds are more inexpensive than the raw material for the conventional brolonged release pharmaceutical without requiring special equipment nor step.
