  • Delivery device for orally administered therapeutic agents
    Patent number: 4981468
    Abstract: An improved device for containing and administering orally active therapeutic agents is described. A unit dose of a therapeutic agent in free-flowing form is retained and positioned for oral administration in a tube adapted to deliver the dose with a flow of liquid drawn through the tube by normal sipping action of a patient. The combination of small particle size and high flow rates into the alimentary canal allow dosage administration with minimal sensed contact with the oral cavity. The invention is particularly advantageous for the administration of orally active therapeutic agents to pediatric and geriatric patients.
