Description

A kind of Rifapentinum capsules and preparation method thereof
Technical field
The present invention relates to field of medicine preparations, more particularly to a kind of Rifapentinum capsules and preparation method thereof.
Background technology
, for powder directly mixes, the technique is through multidirectional fortune after supplementary material sieves to technique prepared by Rifapentinum capsules tradition Dynamic mixer carries out the mixing of several minutes.Due to characteristic factor (brick-red or kermesinus the crystallinity powder of main ingredient in the product End, powder is thin and specific certain viscosity) production difficulty of filling work procedure is increased, therefore the physicochemical property of main ingredient influences it to fill in itself Amount difference, while also have impact on dissolution rate, former technique is difficult to be effectively improved the mobility of powder, easily causes filling work procedure to produce When produce capsule content uniformity is exceeded, pill weight variation is big phenomenon.Meanwhile, Rifapentine hydrolabil, former technique is to raw material Do not deal with, easily cause feed degradation in storage phase, cause relevant material exceeded.
The content of the invention
The Rifapentinum capsules loading amount that the present invention is produced to solve the direct mixing granulation of original powder in the prior art is poor A kind of different big problem, there is provided Rifapentinum capsules and preparation method thereof.
To achieve the above object, the present invention uses following technical scheme:
The first aspect of the invention is to provide a kind of preparation method of Rifapentinum capsules, by Tween 80, HPMC and K12 Melt into adhesive in straight alcohol is added, prepared Rifapentine particle of spraying is carried out to Rifapentine raw material using the adhesive;Again By melt into coating solution in HPMC, BHA and vitamin C addition straight alcohol, and the Rifapentine particle is entered using the coating solution Row hydrojet is coated prepared Rifapentine coated granule;Finally the Rifapentine coated granule is mixed is carried out always with pregelatinized starch It is filled after mixed, Rifapentinum capsules is obtained.
Further, the preparation method of described Rifapentinum capsules, specifically includes following steps:
1) by Tween 80, HPMC and K12Straight alcohol melt into adhesive is added, 100 mesh sieves are crossed, it is standby;
2) Rifapentine of recipe quantity is placed in granulating coated pot, when temperature of charge reaches 35 DEG C in granulating coated pot Start top spray granulation, below 40 DEG C, until all having sprayed, material crosses 20 mesh sieves to control material temperature in whole pelletization Net, rejects and is more than 20 mesh particles, and Rifapentine particle is obtained;
3) HPMC, BHA and vitamin C are added into straight alcohol melt into coating solution, crosses 100 mesh sieves, it is standby;
4) using step 3) obtained in coating solution to step 2) obtained in the Rifapentine particle carry out bottom spray and be coated, it is whole Control material temperature is below 40 DEG C in individual coating process, until all having sprayed, material crosses 20 eye mesh screens, rejects and is more than 20 mesh Grain, is obtained Rifapentine coated granule;
5) finally by step 4) be coated after Rifapentine coated granule admix pregelatinized starch and always mixed, refill Product.
It is further preferred that in the preparation method of described Rifapentinum capsules, counting by weight, the sharp good fortune spray Fourth particle is formulated by following components:
