Title:
医薬組成物の放出のためのパネル化カプセルシェル
Document Type and Number:
Japanese Patent JP2011500627
Kind Code:
A
Abstract:
Capsule shells for use in multi-part dosage forms have generally cylindrical shell members with a snap fit component on an interior surface adjacent an open end, for connection to a linker part of the dosage form. The shell member also has a plurality of spaced apart integrally formed thin (relative to circumferentially adjacent shell member portions) panels located adjacent a closed shell member end, for preferential dissolution and release of pharmaceutical compositions from the shell member interior. The ratio of the thickness of the panels to the thickness of the shell member ranges from about 0.2 to about 0.6. The panels can be integrally formed together with the shell member as reliefs or depressions on the inner surface of the shell member by injection molding, and panel thicknesses as thin as about 0.1 mm can be achieved.
