Abstract

The invention discloses an empty capsule and a preparation method thereof. The empty capsule is high in stability, good in medicine compatibility and free of mutual effect. The empty capsule disclosed by the invention is low in water content and high in hygroscopicity resistance, so that content is unlikely to cake, and the shell of the capsule is unlikely to deform, harden and crisp for disintegration. The empty capsule has low requirements on storage conditions, does not crisp in low humidity environments and has good stability at a high temperature, and the body of the capsule does not deform. The raw materials of the empty capsule come from non-animal sources, thus no potential risk of accumulated growth hormone or medicine remaining in animals exists, and the empty capsule accords with the requirements of vegetarianism, special culture and religion.

Description

technical field [0001] The invention relates to an auxiliary material for pharmaceutical preparations and a preparation method thereof, in particular to a hollow capsule and a preparation method thereof. Background technique [0002] Capsule preparations are widely used in the field of medicine as an important pharmaceutical dosage form, and hollow capsules are the main auxiliary materials for processing pharmaceutical capsule preparations. Most of the currently used hollow capsules are processed from gelatin, and the hollow capsules made of gelatin usually have some defects, such as easy hardening, brittleness and difficult disintegration. In addition, due to the limited source of gelatin, it will react with some drugs and have poor compatibility, and gelatin may have antigenicity as a heterologous protein. In addition, because gelatin is produced with pig bones and pigskin as raw materials, it is taboo to take it due to religious reasons, such as Islam and Judaism, so tha...
