Abstract

In a solid pharmaceutical preparation containing 1) a basic medicinal component having an unpleasant taste; 2) a saccharide; 3) a polyanionic polymer; 4) a corrigent; and 5) carboxymethylcellulose, the unpleasant taste of the basic medicinal component having an unpleasant taste can be satisfactorily masked and excellent properties such as quick disintegration, appropriate preparation strength and high storage stability over a long period of time, etc., can be achieved. Further, a quickly disintegrating solid pharmaceutical preparation containing a medicinal component, a sugar alcohol and carboxymethylcellulose has excellent properties such as quick disintegration, appropriate preparation strength, high storage stability over a long period of time, etc.

Claims (4)

1. A solid pharmaceutical preparation in the form of a tablet comprising 1) pioglitazone hydrochloride, 2) 5 to 97 parts by weight of D-mannitol, 3) 1 to 50 parts by weight of sodium carboxymethylcellulose, 4) 0.1 to 15 parts by weight of sodium glutamate, and 5) carboxymethylcellulose, all parts by weight being based on 100 parts by weight of the solid pharmaceutical preparation, wherein the time for complete disintegration of the solid pharmaceutical preparation by human saliva in the oral cavity of a healthy adult ranges from 5 to 90 seconds.

2. The pharmaceutical preparation according to claim 1 , wherein the time for complete disintegration ranges from 5 to 60 seconds.

3. The pharmaceutical preparation according to claim 2 , wherein the time for complete disintegration ranges from 5 to 30 seconds.

4. A process for manufacturing a solid pharmaceutical preparation, which comprises the steps of mixing a composition comprising pioglitazone hydrochloride D-mannitol, and 1 to 50 parts by weight of sodium carboxymethylcellulose, and a composition comprising D-mannitol and 0.1 to 15 parts by weight of sodium glutamate, and then compression-molding the resultant mixture, the total amount of D-mannitol being 5 to 97 parts by weight and all parts by weight being based on 100 parts by weight of the solid pharmaceutical preparation, wherein the time for complete disintegration of the solid pharmaceutical preparation by human saliva in the oral cavity of a healthy adult ranges from 5 to 90 seconds.
