The invention relates to a carragheenan and
potassium chloride gelled hydroxypropyl methylcellulose enteric-coated hollow
capsule, and belongs to the technical field of the production of hollow capsules. The hollow
capsule is characterized in that the hollow
capsule is prepared through mixing a main
raw material hydroxypropyl methylcellulose with carragheenan and
potassium chloride under a special condition, the hollow capsule has the characteristics of timely disintegration, low
water content, suitableness for medicines having strong hygroscopic property and being sensitive to water, small influences of a dissolve-out medium to the shell of the capsule, high
drug compliance, long storage duration data, no deterioration within 3-4 years, low condition requirements on the storage and the transportation, difficult crushing in the low
humidity environment, difficult deformation,
putrefaction and deterioration in the high temperature environment, according with the requirements of populations having all culture backgrounds because of pure
vegetable fibers, almost no
pollution in the production process, secondary re-dissolving utilization of
tailings, omission of the commonly-used surfactants and plasticizers, acceleration of the gelling speed by reducing the gelling temperature only through utilizing
potassium chloride to assist the carragheenan, additive reduction, production cost reduction, and suitableness for the
mass popularization.
