Abstract
A controlled antacid delivery form having an acid neutralizing component in a matrix including a gel-forming, swelling agent and a water insoluble lipid material. These materials are mixed with the antacid component, together with a large amount of sweet excipient, and compressed at high pressure to provide an antacid lozenge which dissolves very slowly in the mouth. A method for controlled antacid delivery wherein the controlled antacid delivery form is slowly dissolved in the mouth and neutralizes the stomach acid over a long period of time with surprising little antacid, while bathing the esophageal lining with antacid. When the controlled antacid delivery form includes a mixture of antacids having different reactivities towards acid, said method provides for substantially complete utilization of each component.
