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.
Claims26
A tablet, comprising
- a. a liquid active ingredient;
- and
- b. a powdered material that 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 compressed to form a tablet.
A capsule, comprising
- a. a liquid active ingredient;
- b. a powdered material that has adsorbed a high proportion by weight of the liquid active ingredient while maintaining characteristics of a solid;
- and
- c. a capsule shell into which the liquid active ingredient and the powdered material are disposed.
A benzonatate formulation, comprising:
- a. fumed silica;
- and
- b. liquid benzonatate mixed with the fumed silica to form a solid-like substance.
A method of making a tablet from a liquid active ingredient, comprising the steps of:
- a. mixing the liquid active ingredient with a powdered material capable of adsorbing a high proportion of liquid while retaining solid properties to form a solid-like substance, the liquid active ingredient in a proportion to the powdered material that retains solid properties;
- b. adding a binder to the solid-like substance to form a combination;
- c. granulating the combination to form granules;
- and
- d. compressing the granules to form tablets.
