  • Publication number: 20060222700
    Abstract: A tablet includes a liquid active ingredient, such as benzonatate, and a powdered material, such as fumed silica. The powdered material has adsorbed a high proportion by weight of the liquid active ingredient while maintaining characteristics of a solid. The liquid active ingredient and the powdered material are compressed to form a tablet. To make the tablet, the liquid active ingredient is mixed with the powdered material in a proportion that retains solid properties. A binder is added to the solid-like substance to form a combination. The combination is granulated to form granules. The granules are compressed to form tablets. The material may also be disposed in capsules.

  • Publication number: 20060051298
    Abstract: A pharmaceutical composition includes a therapeutic amount of an active ingredient and at least one gel-forming granule. The gel-forming granule forms a gel when exposed to an aqueous liquid and is coated with an outer coating that is sufficiently brittle so that when the tablet is crushed, a portion of the outer coating will break open so as to expose the gel-forming granule. The outer coating includes a material that resists dissolution when exposed to gastric fluids.
