Abstract
A chewable aspirin and buffering material tablet and method for producing same is disclosed herein. In a single dosage form the aspirin and buffering materials are integrally dispersed and bound in a fatty material of chocolate, synthetic chocolate or hydrogenated tallow. The tablet is for gastrointestinal applications and is especially adopted for use with animals, particularly dogs, and can be molded into a variety of shapes including that of a miniature dog bone.
Claims18
A chewable shelf-stable buffered aspirin tablet comprising:
- (a) a fatty material as a principal ingredient selected from a class consisting of chocolate, synthetic chocolate, and hydrogenated tallow,
- (b) as a minor ingredient by weight, unbuffered aspirin selected from a group consisting of granulated aspirin, micronized aspirin, powdered aspirin, microencapsulated aspirin, and mixtures thereof, and
- (c) as a minor ingredient, by weight, an amount of buffering material sufficient to buffer the effect of said aspirin on the gastrointestinal mucosa of a subject ingester, said buffering material being finely divided and selected from the class comprised of:
- aluminum carbonate, aluminum hydroxide (or as aluminum hydroxide-hexitol stabilized polymer, aluminum hydroxide-magnesium hydroxide codried gel, aluminum hydroxide-sucrose powder hydrated), aluminum phosphate, aluminum hydroxy carbonate, dihydroxyaluminum sodium carbonate, aluminum magnesium glycinate, dihydroxyaluminum aminoacetate, dihydroxyaluminum amionacetic acid, bismuth aluminate, bismuth carbonate, bismuth subcarbonate, bismuth subgallate, bismuth subnitrate, calcium carbonate, calcium phosphate, hydrated magnesium aluminate activated sulfate, magnesium aluminate, magnesium aluminosilicates, magnesium carbonate, magnesium glycinate, magnesium hydroxide, magnesium oxide and magnesium trisilicate, and mixtures thereof, said aspirin and buffering materials being individually separately coated by said fatty material whereby chemical reaction between the aspirin and buffering material is prevented, said aspirin and buffering material being uniformly dispersed and bound in said fatty material in a tablet form.
1 more element
