Abstract

Abstract Chewable medicament tablets are made from coated rotogranules of a medicament wherein the rotogranules are formed from a granulation mixture of medicament, e.g. famotidine binder, e.g. polyvinylpyrrolidone, and carrier, e.g. lactose and the rotogranules are coated with cellulose acetate, cellulose acetate butyrate or a combination thereof and polyvinyl pyrrolidone and a process for making such tablets and a method of providing taste masking of medicaments utilizing such coated rotogranules.

Claims Analysis

Total Claims: 11
Claim 1
Independent Claim 46 words
A chewable tablet of a medicament comprising compressed coated rotogranules, said coated granules individually comprising medicament which has been rotogranulated with a binder and a carrier material and coated with a polymer blend of cellulose acetate, cellulose acetate butyrate or a combination of both with polyvinylpyrrolidone.
Claim 2
Dependent Claim 21 words
The chewable tablet of claim 1, wherein the medicament is famotidine, loperamide, cimetidine, ranitidine, a salt thereof or a combination thereof.
Claim 3
Dependent Claim 37 words
The chewable tablet of claim 1 or claim 2, wherein the coating mixture has a weight ratio in the range of from 95:5 to 60:40 of cellulose acetate, cellulose acetate butyrate or a combination thereof to polyvinylpyrrolidone.
Claim 4
Dependent Claim 31 words
The chewable tablet of any one of claims 1 to 3, wherein the polymer blend coating comprises from 5 to 20% by weight of the total weight of the coated granules.
Claim 5
Dependent Claim 39 words
The chewable tablet of any one of claims 1 to 4, wherein the rotogranules comprise from 2 to 85% medicament, 4 to 10% binder and 10 to 94% carrier by weight of the total weight of the uncoated granule.
Claim 6
Dependent Claim 25 words
The chewable tablet of any one of claims 1 to 5, wherein the medicament is famotidine, the binder is polyvinylpyrrolidone and the carrier is lactose.
Claim 7
Dependent Claim 20 words
The chewable tablet of any one of claims 1 to 6, wherein the coated granules are substantially spherical in shape.
Claim 8
Dependent Claim 18 words
A rotogranulation composition for use in preparing a chewable tablet of any one of claims 1 to 7.
Claim 9
Dependent Claim 40 words
A process for producing coated medicament rotogranulations comprising the steps of: preparing a rotogranulation composition of medicament, binder and a carrier; and coating the medicament rotogranulation composition with cellulose acetate, cellulose acetate butyrate or a combination of both and polyvinylpyrrolidone.
Claim 10
Dependent Claim 26 words
The process of claim 9, further including the step of forming a chewable tablet by compressing the coated medicament rotogranulation composition in the presence of excipients.
Claim 11
Dependent Claim 20 words
The process of claim 9 or claim 10, which produces a product of any one of claims 1 to 8.
