Abstract

An improved compressed soft chewable tablet is provided, which may contain an antacid or other active ingredient, has good flexibility, is breakage resistant and disintegrates immediately upon chewing. The tablet of the invention is formed of particles of antacid and/or other active ingredient which are isolated from other ingredients of the tablet, preferably by admixing particles of active ingredient with particles formed of edible fat or oil absorbed on a fat-absorbing material, such as microcrystalline cellulose and blending such particles with one or more tablet bonders; the tablet also includes additional amounts of tablet bonders, flavors and other conventional tabletting aids to help in making the tablet more palatable. Upon chewing, the tablet is quickly converted to a smooth creamy non-gritty palatable emulsion.

Claims

1. A compressed chewable antacid tablet having good hardness and flexibility and easy bite-through which comprises a blend of (a) a particulate pretreated fat composition comprising an edible fatty material comprising hydrogenated tallow, hydrogenated vegetable oil, almond oil, coconut oil, corn oil, cottonseed oil, refined linseed oil, light liquid petrolatum, heavy liquid petrolatum, olein, olive oil, palm oil, peanut oil, persic oil, sesame oil, soybean oil or safflower oil, a fat sorbing material having the fatty material sorbed thereon or therein, the fat sorbing material comprising microcrystalline cellulose, cornstarch, tapioca, dextrin, sucrose, sorbitol, xylitol or mannitol, and one or more tablet bonders said tablet bonders comprising tabletting sugar, dextrose monohydrate or mixtures thereof, blended therewith or mixtures thereof with one or more antioxidants, flavors, colorant or mixtures thereof;

(b) a pretreated active ingredient composition comprised of a mixture of particles of active ingredient which comprises an antacid, or mixtures thereof with edible oil, binder, emulsifier, flavor, colorant or mixtures thereof;

the particles of active ingredient being coated with the other components of said pretreated active ingredient composition; and

(c) a pretreated direct compaction tabletting aids composition comprising one or more tablet bonders comprising tabletting sugar, dextrose monohydrate or mixtures thereof, or mixtures thereof with flavors.

2. The compressed chewable tablet as defined in claim 1 wherein said antacid material comprises calcium carbonate, magnesium carbonate, magnesium hydroxide, aluminum hydroxide, or mixtures thereof.

3. The compressed chewable tablet as defined in claim 1 wherein said fatty material is employed in a weight ratio to said fat-sorbing material of from about 0.625:

1 to about 1.875;

1.

4. The compressed chewable antacid tablet as defined in claim 1 wherein the particulate pretreated fat composition (a) includes as a fat-sorbing material microcrystalline cellulose, hydrogenated vegetable oil as a fatty material absorbed in the microcrystalline cellulose, or mixtures thereof with a colorant or mixtures thereof with an antioxidant or mixtures thereof with an anti-flatulent, tablet bonders comprising tabletting sugar, dextrose monohydrate or mixtures thereof or mixtures thereof with one or more flavors, the pretreated active ingredient composition (b) comprises particles of one or more antacids comprising calcium carbonate, aluminum hydroxide, magnesium hydroxide, or a mixture of all of said antacids, a binder, comprising carboxymethyl cellulose to help flavor and emulsifier to stick to fat-absorbed particles, and impart a slippery mouth feel, an emulsifier comprising polyglycerol ester of fatty acid to help decrease surface tension on the tongue and stimulate salivation, an edible oil comprising a vegetable oil to help plating out of the emulsifier on the antacid particles, and flavor, and the pretreated direct compaction tabletting aids composition comprises tablet bonders, comprising tabletting sugar, dextrose monohydrate or mixtures thereof, and flavors and flavor oils.

5. A method for forming a compressed chewable antacid tablet as defined in claim 1 which comprises

forming a particulate pretreated fat composition by melting the edible fatty material, admixing the melted fatty material with colorant, and antioxidant, admixing the resulting mixture with the fat-sorbing material thereby causing the fatty material to be sorbed on the fat-sorbing material, the mixture at this juncture exhibiting the appearance of a fatty powder, allowing the resulting mixture to dry and harden, and after sifting the mixture, blending same with one or more tabletting bonders and flavors, to form the particulate pretreated fat composition (a);

forming the pretreated active ingredient composition (b) by blending particles of active ingredient and binder, separately blending together one or more emulsifiers, edible oil, and flavor, and blending each of the above mixtures until a free-flowing powder is obtained wherein said particles of active material are coated with binder, oil, flavor and emulsifer;

forming the pretreated direct compaction tabletting aids composition by mixing one or more tablet bonders with one or more flavors;

blending the above mixes; and

forming a compressed tablet from the resulting mixture.
