Beschreibung
Zusammenfassung:	PURPOSE:To obtain a chitosara hard-capsule capable of uniformly releasing the drug from the capsule in the large intestine by moderately increasing the viscosity of the chitosan solution used as a raw material, thereby preventing the sagging of the liquid during the drying of the capsule and uniformizing the wall thickness of the capsule. CONSTITUTION:The chitosan hard-capsule is composed of a chitosan having a degree of deacetylation of 60-98mol% and incorporated with 5-50wt.% of fine silica particles based on the total capsule. The present invention also relates to a process for the production of the capsule.
