Abstract
The invention provides a thyroid tablet composition freeze-dried tablet and a preparation method thereof, and relates to the technical field of medicines and medicine production. The thyroid tablet composition freeze-dried tablet comprises thyroid tablet, starch and cane sugar, wherein the starch and the cane sugar are taken as auxiliary materials. Common corn starch is treated by a heating technique, so that the bonding and disintegration functions of the starch in the tablet can be improved, and the formability of the tablet is improved. The thyroid tablet composition freeze-dried tablet only needs two auxiliary materials namely the starch and the cane sugar. The thyroid tablet composition freeze-dried tablet adopts a twice-temperature-reduction and twice-temperature-rise freeze-drying technique, and due to twice temperature reduction and twice temperature rise, the formability of the tablet is better, and the dissolution rate of the tablet is improved, so that the bioavailability of the tablet is improved; the tablet overcomes the defects of a common thyroid tablet, the types and the quantities of the auxiliary materials in the thyroid tablet are reduced, the dissolution rate of the tablet is large, the bioavailability of the tablet is high, and the curative effect and the safety of clinical medication are ensured.
Description
Technical field
The present invention relates to medicine and medical production technical field, be specifically related to a kind of thyroid tablet composition freeze-drying sheet and preparation method thereof.
Background technology
This product Main Ingredients and Appearance is: be the thyroid body getting the edible animals such as pig, cattle, sheep, and removing connective tissue and fat, rub, dehydration, defat, the temperature below 60 DEG C is dry, and porphyrize is made.
Existing clinical common dosage forms is the thyroid tablet of synthetic.This product is thyroxin medicine, induction nascent protein comprises the synthesis of specific enzymes system, Function protein matter, carbohydrate and fat three large materials, and water, the metabolism of salt and vitamin. due to thyroxin inducing cell film Na+-K+ pump synthesis and strengthen its vigor, energy metabolism is strengthened. thyroxin (mainly T3) combines with core internal specific receptor, there is change of configuration in the latter, form dimer, special sequence on the receptor activated and DNA, thyroxin response element combines, thus the transcript and expression of controlling gene (target gene of thyroxin), promote the synthesis of new protein (being mainly enzyme).
In common thyroid tablet 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 supplementary product kind and consumption in thyroid tablet, improve thyroid tablet bioavailability, ensure 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, 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, to human-body safety, but being used alone starch has no report as adjuvant freeze-dry process production thyroid tablet lyophilizing sheet.
Summary of the invention
Technical problem to be solved by this invention is the defect overcoming prior art, and propose a kind of thyroid tablet composition freeze-drying sheet and preparation method thereof further, 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 thyroid tablet composition freeze-drying sheet, adjuvant is done with starch and sucrose, produce with freeze-dry process, this tablet overcomes the shortcoming of above-mentioned common thyroid blade, decrease supplementary product kind and consumption in thyroid blade, this sheet dissolution is large, and bioavailability is high, ensure that curative effect and the safety of clinical application.
A kind of thyroid tablet composition freeze-drying sheet, is prepared from by following raw material:
A preparation method for thyroid tablet composition freeze-drying 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 4-6, 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 thyroid tablet 10 grams, add in 1L Semen Maydis-sucrose solution, stir 25 ~ 35 minutes;
Medicinal liquid is sub-packed in drug-containing dish after measuring thyroid tablet content by E, medicinal liquid, 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 thyroid tablet composition freeze-drying sheet.
Described starch selects corn starch, preferably the corn starch solution of 10% (W/V).
Beneficial effect of the present invention is:
The preparation method of a kind of thyroid tablet composition freeze-drying sheet of the present invention, heating process process is carried out to common corn starch, starch bonding in tablets, disintegration can be improved, improve the mouldability of tablet, in thyroid tablet composition freeze-drying sheet, dosage of sucrose is 8.5% (W/V), it is the hardness reinforcer of this tablet, and plays flavored action.Thyroid tablet composition freeze-drying sheet only needs starch and sucrose two kinds of adjuvants.The freeze-dry process of two liters falls in thyroid tablet 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.
