Abstract
The invention provides a cephalosporin medicine capsule preparation.A capsule shell of the cephalosporin medicine capsule preparation is an empty capsule shell containing hydroxypropyl starch.The capsule preparation has good vitro dissolution and bioavailability, solves bitter taste regurgitation of cephalosporin medicine, and reduces adverse reactions such as nausea, diarrhea, stomachache, stomach discomfort, burning senseation, inappetence and inappetence.
Description
Technical field
The present invention relates to the capsule preparations of a kind of cephalosporins medicine, be specially a kind of cephalosporins medicine capsule adopting hydroxypropyl starch Capsules shell to prepare, belong to pharmaceutical technology field.
Background technology
Capsule is widely used in pharmaceuticals industry, as the capsule shells of one of main component, is a kind of shell protecting medicine, and it can not only protect medicine not to be destroyed, and also reduces medicine to respiratory tract and Alimentary stimulation.
But, there is multiple security risk in tradition gelatine capsule, because tradition gelatine capsule is that the animal proteinum colloid gelatin prepared using the skin of animal, bone hydrolysis is as capsule shell material.Due to limited source, illegal businessman utilizes the processing leftover pieces of industrial hides, or the non-leather that reclaims is treated makes the animal derived Capsules that edible or pharmagel thus supports and would be likely to occur heavy metals exceeding standard, water content is too high, cholesterol levels is high and causes the security risks such as animal sources infectious disease.
Hydroxypropyl starch capsule then possesses the remarkable advantages such as natural safety, long shelf-life, adaptation be wide.Starch capsule derives from natural Maninot esculenta crantz., and starch is after degenerative treatments, it is possible to effectively improve the character of gelatinized corn starch, strengthens the hydrophilic of gelatinized corn starch, makes the transparency of gelatinized corn starch and stability increase to some extent, not easily precipitate, good film-forming property, have excellent toughness.The many advantages such as not only have that raw material sources are natural, safety good, wide adaptability, storage are stable, it is thus also avoided that the zoonosis of conventional capsules.
Prior art as, CN104083768A discloses one and prepares Capsules shell, is made up of the composition of following weight proportion: component A: starch and derivant 15-30 part thereof；Component B: plant gum 2-13 part；Component C: coloring agent 0-5 part.Wherein, starch described in component A and combination that derivant is starch and hydroxypropyl starch thereof.
Cephalosporins has become clinical practice antibiotic the most widely, is generally divided into oral and injection by route of administration, and peroral dosage form includes tablet (including dispersible tablet etc.), capsule, granule, dry suspension etc..But, cephalosporins all has bad taste of smelling, and the medicines such as cephalo esters such as CEFUROXIME AXETIL also have strong bitterness, and patient's compliance is poor, common cephalosporins medicine capsule, when patient takes, there is the bitterness that reflux causes patient uncomfortable.Additionally, cephalosporins medicine there is also the untoward reaction such as nauseating, diarrhoea, stomachache, stomach discomfort, burn feeling, inappetence, constipation.
Although, prior art is instructed capsule can cover the bad of cephalosporins medicine and smell taste, but general capsule is when dissolution test, dissolution medium (water or gastric juice etc.) gelation met by medicine, medium can not continue deeper into inside, and drug dissolution is very low, causes that bioavailability is low, therefore, the research and development predicament of cephalosporins medicine capsule is caused.
At present, cephalosporins medicine capsule, in storing process, is subject to extraneous factor impact, it is easy to open loop is decomposed, and polymer content increases, and causes that its stability reduces.
Present inventors have surprisingly found that the capsule of cephalosporins medicine prepared by the employing Capsules shell containing hydroxypropyl starch can solve above-mentioned technical problem well.
Summary of the invention
It is an object of the invention to provide the capsule preparations of a kind of cephalosporins medicine, not only there is good In Vitro Dissolution and bioavailability, but also solve its bitterness reflux, reduce such as feel sick, diarrhoea, stomachache, stomach discomfort, burn feeling, inappetence, the untoward reaction such as constipation.
