Hypromellose enteric empty capsule gelated by gellan gum and potassium chloride

A technology of hypromellose and hollow capsules, which can be used in capsule delivery, cosmetic preparations, medical preparations of non-active ingredients, etc. It can solve the problem of insufficient film-forming properties and storage stability of capsules, and the disintegration speed of gelatin capsules. Slow, hollow capsule safety hazards and other problems, to achieve the effect of reducing the risk of drug hygroscopicity, no risk of animal infectious diseases, and not easy to rot

Problems solved by technology

[0004] However, gelatin capsules obviously have the defect of slow disintegration speed. At the same time, the huge gelatin empty capsule market and its industrial chain have also brought many quality problems and safety risks.
After the "Chromium Exceeding Standard Capsule Incident", more attention has been paid to the safety issues of capsules; at the same time, with the occurrence of animal diseases such as "mad cow disease" and "foot-and-mouth disease", people have a lot of interest in making gelatin raw materials from animal leather and bones. There is great anxiety, the empty capsules mainly produced from animal gelatin have great potential safety hazards
[0005] In view of this, scientific research institutions at home and abroad have strengthened the research on plant-based capsules. So far, a variety of non-gelatin hollow capsules have been developed. 68%-88% pullulan, 10%-30% hypromellose, 1%-3% gel, 0.1%-0.5% coagulant, 0.1%-0.5% Surfactants and 0.1%-0.3% pigments are prepared into glue and dipped in glue. This patent solves the problems of slow disintegration speed and potential safety hazards of gelatin capsules, but it is obvious in the film-forming and storage stability of the capsule body. Not enough, it also has adverse effects on certain drugs in the capsule, and the surfactant in it has been expressly banned

Abstract

A hypromellose enteric empty capsule gelated by gellan gum and potassium chloride belongs to technical field of empty capsule production, is characterized in that hypromellose is used as a main raw material and mixed with the gellan gum and potassium chloride to prepare the empty capsule, and has the benefits that the disintegration is timely, moisture content is low, the empty capsule is suitable for medicines which have strong hygroscopicity and are sensitive to water, the influence of dissolved mediums on a capsule shell is small, the medication compliance is high, the storage period is long, the empty capsule can not go bad within 3-4 years, requirements on storage and transportation conditions are low, the empty capsule is less susceptible to fragmentation at a low-moisture environment, is insusceptible to deformation at a high-temperature environment, and has low probabilities of rottenness and deterioration; the empty capsule is made from pure vegetable fibers, and can meet requirements of all cultural backgrounds and religious groups; the manufacturing process is almost free from pollution, tailings can be again dissolved for reuse; frequently-used surface-active agents and plasticizers are eliminated, the gelating speed is accelerated only by using the potassium chloride to help the gellan gum to condense so as to reduce the gelating temperature, accordingly, the additives are reduced, and the production cost is reduced; the empty capsule is suitable for mass promotion.

Description

technical field [0001] The invention belongs to the technical field of hollow capsule production, in particular to a plant-based enteric-coated hollow capsule made of gellan gum and potassium chloride gel prepared from hypromellose. Background technique [0002] The hollow capsule is composed of a cap and a body made of refined medicinal materials, and is used to hold solid medicines; such as self-made powders, health products, medicines, etc., which solves the problems of difficult entrance and poor taste for users, and truly realizes The good medicine is no longer bitter; because the hollow capsules are easy to swallow and can effectively mask the unpleasant taste and smell of the contents, they are becoming more and more popular among patients. [0003] The current hollow capsules mainly include animal gelatin capsules and various vegetable capsules. In my country, gelatin hollow capsules account for the vast majority. At present, gelatin hollow capsules have been widely ...
