Abstract

A fast-release enteric tablet containing aconitine is proportionally prepared from aconitine-type medicine, fast-releasing additive, enteric polymer, plasticizer and solvent through superfine pulverizing, mixing, tabletting and coating.

Description

A kind of enteric-coated quick releasing sheet that contains aconitine and preparation method thereof
Affiliated technical field
The present invention relates to contain the medicine of organic compound, particularly contain the preparation method of the oral formulations and the said preparation thereof of aconitine.
Background technology
Medicine aconitine with easing pain and diminishing inflammation effect is an isolating aconite alkaloids from Ranunculaceae aconitum plant (Aconitum), be mainly used in diseases such as treatment rheumatism, rheumatoid and osteoarthritis, the history in existing more than 20 year of this compounds of clinical practice, its preparation comprises injection, tablet, oral liquid, soft capsule.Often with having an intense pain and the injection site redness, patient dependence is bad in use for injection; Common peroral dosage form take the back oral cavity numb, digestive tract is had stronger stimulation.Studies have shown that, aconitine disperses not open, the too high meeting of local concentration irritates nucous membrane and its hetero-organization consumingly, produces untoward reaction such as calcination, even damages partial biological tissue, for this reason, medicine is the major reason that causes adverse effect in gastral degree of scatter and speed.The Chinese patent file ' radix aconiti kunsezoffii nail element soft capsule and production method thereof ' of the Chinese patent file of publication number CN1107697A ' aconitum kusnezoffii oral tablets, capsule ' and patent No. ZL 98106595.3 all is to be the common oral drugs that primary raw material is made with the bulleyaconitine A, by upper digestive tract disintegrate, absorption.But, bulleyaconitine A under intensive gastric acid condition, facile hydrolysis and the effective ingredient of degrading; In addition, bulleyaconitine A is a kind of alkaloid, generates alkaloidal salt with hydrochloric acid reaction in gastric acid the bioavailability of product is reduced, and the comprehensive function meeting of these two factors reduces the effectiveness of aconitum kusnezoffii oral preparation.Still there is untoward reaction such as taking deutostoma fiber crops, stimulating gastrointestinal road in the former; And the latter is poor because of medicine extended release and patient's compliance, can not give full play to the effect of bulleyaconitine A.And use the patient of medicine mostly to be chronic disease, and being subjected to the influence of these slight illness, a little less than most patient's body constitution, gastrointestinal function is poor.Therefore, need to eliminate aconitine strong impulse, unstability, absorbency issue.
Propose before the present invention, the untoward reaction that during we use at the aconitine clinical drug gastrointestinal intense stimulus is occurred, studied the dynamic process of such drug absorption, such medicine is made enteric coatel tablets, attempt is exempted medicine to the stimulation of stomach and avoid the medicine inactivation that all or part of decomposition causes in gastric juice, but description of test, common enteric coated tablet can not be exempted the stimulation to intestinal.
Summary of the invention
The object of the present invention is to provide a kind of not stimulating gastrointestinal road, easily absorb, can give full play to the aconitine enteric-coated quick releasing sheet oral formulations of medicinal property.
The enteric coatel tablets of the present invention by being formed in rapid release in the intestinal, eliminate such medicine whole gastral stimulation is realized above-mentioned purpose.Concrete scheme is as follows:
The weight ratio of enteric-coated quick releasing slice prescription component and content is: aconitine medicine 0.14%~20%, disintegrating agent 1.3%~50%, label adjuvant 1.0%~35%; Enteric polymer 5%~25%, plasticizer 0.2%~5%; And volume ratio is the solvent of above component 70%~93%.
Described enteric-coated quick releasing sheet contains aconitine medicine 0.2~10mg.
Described label disintegrating agent is one or more in cross-linked carboxymethyl cellulose sodium, crosslinked carboxymethylstach sodium, cyclodextrin, low-substituted hydroxypropyl cellulose, microcrystalline cellulose, the soluble starch.
Described enteric polymer is one or more of cellulose acetate phthalate ester, acid polyethylene phthalate ester, polyacrylic resin II or III number, Lac, methacrylic acid copolymer, cellulose acetate benzenetricarboxylic acid ester, hypromellose phthalate ester.
Contain in citric acid, L MALIC ACID, succinic acid, maleic acid, fumarase, glucose, Fructus Citri tangerinae essence, strawberry essence, the apple essence one or more in the described label adjuvant, to improve sense organ olfactory sensation or fragrance.
Preparation method at the enteric-coated quick releasing sheet that contains aconitine of above scheme has following steps:
(1) weighing aconitine medicine carries out super-refinement and crosses 1000 orders,
(2) prescription that proposes according to above claim, disintegrating agent is crossed 60 orders through refinement, adjuvant is crossed 100 orders through refinement, and with step (1) refinement after behind the medicine mixing, direct compression or make instant label with the solvent wet method,
(3) prescription that proposes according to above claim carries out film coating with enteric material to label.
The enteric-coated quick releasing formulation product of the present invention preparation shows through experiment: it is a kind of patient's gastrointestinal tract to be stimulated bulleyaconitine A class aconitine pharmaceutical preparation---the enteric rapid release oral agents little, that bioavailability is high; Stripping in gastric juice<10%, enteric solubility is good; The rapid release experiment shows that sample can rapid disintegrate become microgranule in intestinal juice; Bioavailability can improve more than 5%; The easing pain and diminishing inflammation of aconitine is active to be improved more than 5%; And placed at normal temperatures 2 years, the every index of product all meets the requirements.
