Abstract
The invention provides a vitamin B1 composition lyophilized tablet and a preparation method thereof, and relates to the technical field of medicine and medicine production. The tablet is prepared from vitamin B1, starch and sucrose, wherein the starch and sucrose are used as auxiliary materials, and common corn starch is subjected to heat process, so that adhesion and disintegration effects of the starch in a tablet can be improved, and the moldability of the tablet can be improved; and only starch and sucrose are needed in the vitamin B1 composition lyophilized tablet. According to the preparation method, a two-decreasing two-increasing lyophilizing process is adopted for the vitamin B1 composition lyophilized tablet, the moldability of the tablet can be better by means of twice cooling and twice heating, the solubility of the tablet can be improved, and the bioavailability of the tablet can be improved; the tablet is capable of overcoming the defect of conventional vitamin B1 tablets and reducing the types and usage of auxiliaries in the vitamin B1 tablets, is high in solubility and high in bioavailability, and can be used for guaranteeing the curative effect and safety of clinical administration.
Description
Technical field
The present invention relates to medicine and medical production technical field, be specifically related to a kind of vitamin B
1composition freeze-drying sheet and preparation method thereof.
Background technology
Vitamin B
1it is a kind of vitamin B group that pyrimidine ring and thiazole ring are combined into by methylene.
Molecular formula: C
12h
17clN
4oSHCl
Molecular weight 337.27
Existing clinical common dosage forms is all the product of chemosynthesis.This product participates in catabolism of carbohydrate with co-enzyme form, has the effect of neuroprotective system; Can also enterogastric peristalsis be promoted, increase appetite.Clinical common formulations is tablet and injection.
Common vitamin B
1in sheet containing supplementary product kind and quantity more, generally will use filler, lubricant, disintegrating agent, adhesive, correctives etc., its disintegration time reaches 12 minutes, and bioavailability is lower.And increasing research shows that impurity in the incompatibility of the toxic and side effects of adjuvant itself, adjuvant and principal agent, adjuvant etc. all can have an impact to the safety of medicine.
Therefore, provide one can overcome above-mentioned shortcoming, select suitable adjuvant and technique, reduce vitamin B
1supplementary product kind and consumption in sheet, improve vitamin B
1sheet bioavailability, ensures that the safety of clinical application all has positive effect.
Traditional lyophilizing tablet can improve bioavailability, but still need use the adjuvant such as mannitol, gelatin.And mannitol has certain biological activity, gelatin resource-constrained and perishable.
Starch is the basic adjuvant of oral solid formulation, and it is polymerized by glucose molecule, and be commonly used for adhesive, diluent and disintegrating agent in tablets, it is cheap and easy to get, and to human-body safety, but being used alone starch produces vitamin B as adjuvant freeze-dry process
1lyophilizing sheet has no report.
Summary of the invention
Technical problem to be solved by this invention is the defect overcoming prior art, proposes a kind of vitamin B further
1composition freeze-drying sheet and preparation method thereof, said preparation adjuvant is few, good stability, and bioavailability is high.
Technical problem to be solved by this invention realizes by the following technical solutions:
A kind of vitamin B
1composition freeze-drying sheet, does adjuvant with starch and sucrose, and produce with freeze-dry process, this tablet overcomes above-mentioned usual vitamin B
1the shortcoming of sheet, decreases vitamin B
1supplementary product kind and consumption in sheet, this sheet dissolution is large, and bioavailability is high, ensure that curative effect and the safety of clinical application.
A kind of vitamin B
1composition freeze-drying sheet, is prepared from by following raw material:
A preparation method for vitamin B 1 composite lyophilizing sheet, comprises step as follows:
A, take the starch of component amount, add a certain amount of purified water and stir, by pH adjusting agent, the pH value of solution is controlled between 4-5, be then heated to 72 DEG C, be incubated 20 minutes, make the corn starch solution of 5 ~ 15% (W/V);
B, measure purified water 45ml, boil, add 85g sucrose, stir, after dissolving, continue to be heated to 100 DEG C, filter with purified cotton, the appropriate hot distilled water of filter is cleaned, and washing liquid and filtrate merge, and let cool, add appropriate distilled water, make full dose become 100ml, stir evenly, obtain B solution;
The solution that C, the solution and the step B that steps A are obtained obtain mixes, and fully stirs 30 minutes, is down to room temperature and obtains Semen Maydis-sucrose solution;
D, take vitamin B
150 grams, add in 1L Semen Maydis-sucrose solution, stir 25 ~ 35 minutes;
E, medicinal liquid measure vitamin B
1after content, medicinal liquid is sub-packed in drug-containing dish, each drug-containing dish dress 1.0ml;
F, the drug-containing dish that medicinal liquid is housed is put into vacuum freezing drying oven, be cooled to subzero 45 DEG C, keep 2 hours, evacuation, then 0 DEG C is warming up to gradually, keep 2 hours, then be cooled to subzero 45 DEG C, keep 2 hours, be warming up to 0 DEG C gradually again, keep 2 ~ 4 hours, then be warming up to 28 ~ 32 DEG C of dryings 4 ~ 6 hours gradually, whole process vacuum remains on 10 handkerchiefs; Finally the drug-containing dish lid of powder charge is covered tightly, and load aluminium foil bag and carry out sealing and obtain vitamin B
1composition freeze-drying sheet.
Described starch selects corn starch, preferably the corn starch solution of 10% (W/V).
Beneficial effect of the present invention is:
A kind of vitamin B of the present invention
1the preparation method of composition freeze-drying sheet, carries out heating process process to common corn starch, can improve starch bonding in tablets, disintegration, improves the mouldability of tablet, vitamin B
1in composition freeze-drying sheet, dosage of sucrose is 8.5% (W/V), and it is the hardness reinforcer of this tablet, and plays flavored action.Vitamin B
1composition freeze-drying sheet only needs starch and sucrose two kinds of adjuvants.Vitamin B
1the freeze-dry process of two liters falls in composition freeze-drying sheet employing two, and twice cooling, twice intensification can make sheet mouldability better, and shorten the disintegration time of tablet, improve the bioavailability of tablet.
