SECTIONED POLYMER TABLETS Russian patent published in 2009 - IPC B29B9/12 C08J3/12 

Abstract RU 2370365 C2

FIELD: pharmacology.

SUBSTANCE: polymer tablet includes oxygen-sensitive component, oxygen-indifferent component and reaction promoter. Oxygen-sensitive component is placed in first sectioned area, oxygen-indifferent component is placed in second sectioned area. Oxygen-sensitive component becomes oxygen-active in the presence of promoter. Promoter is represented by any substance initiating or accelerating reaction of oxygen-sensitive component with oxygen, and oxygen-indifferent component contacting promoter causes oxygen consumption increase not more than by 10% compared to oxygen consumption without promoter. Promoter amount in direct contact with oxygen-sensitive component is insufficient to initiate of catalyse reaction with oxygen significantly. Also invention claims other versions of polymer tablet and method of thermal tablet processing.

EFFECT: possible thermal processing of components in multicomponent tablets and/or storage in open air or in the presence of oxygen without significant quality deterioration.
