Abstract

The invention provides a sodium bicarbonate composition freeze-dried tablet and a preparation method thereof, relating to the technical fields of medicines and medicine production. The sodium bicarbonate composition freeze-dried tablet comprises sodium bicarbonate, starch and sucrose. Common corn starch is subjected to heat treatment by using the starch and sucrose as auxiliary materials to enhance the bonding and disaggregation actions of the starch in the tablet and enhance the formability of the tablet. The sodium bicarbonate composition freeze-dried tablet only needs the two auxiliary materials starch and sucrose. The sodium bicarbonate composition freeze-dried tablet is prepared by a double-cooling double-heating freeze-drying technique; and the double cooling and double heating can enhance the formability of the tablet and increase the dissolution of the tablet, thereby enhancing the bioavailability of the tablet. The tablet overcomes the defects in the common sodium bicarbonate tablet, reduces the varieties and consumption of the auxiliary materials in the sodium bicarbonate tablet, has the advantages of high dissolution and high bioavailability, and ensures the curative effect and safety of clinic application.

Description

A kind of sodium bicarbonate composition lyophilizing sheet and preparation method thereof

Technical field

The present invention relates to medicine and medical production technical field, be specifically related to a kind of sodium bicarbonate composition lyophilizing sheet and preparation method thereof.

Background technology

Molecular formula NaHCO ₃molecular weight 84.01

This product is antacid, after oral can rapidly in and gastric acid, remove hyperchlorhydria or heartburn symptom, but effect is more weak, the persistent period is shorter.For alkalized urine and acidemia, also can be used for hyperchlorhydria.The stomachache that alleviation hyperchlorhydria causes, heartburn sense (heartburn), acid regurgitation.

In common Sodium Bicarbonate Tablets containing supplementary product kind and quantity more, generally will use filler, lubricant, disintegrating agent, adhesive, correctives etc., its disintegration time reaches 30 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 Sodium Bicarbonate Tablets, improve Sodium Bicarbonate Tablets 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 sodium bicarbonate 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 sodium bicarbonate composition lyophilizing 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 sodium bicarbonate composition lyophilizing sheet, adjuvant is done with starch and sucrose, produce with freeze-dry process, this tablet overcomes the shortcoming of above-mentioned common Sodium Bicarbonate Tablets, decrease supplementary product kind and consumption in Sodium Bicarbonate Tablets, this sheet dissolution is large, and bioavailability is high, ensure that curative effect and the safety of clinical application.

A kind of sodium bicarbonate composition lyophilizing sheet, is prepared from by following raw material:

A preparation method for sodium bicarbonate composition 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 7.5-8.5, 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 sodium bicarbonate 300 grams, add in 1L Semen Maydis-sucrose solution, stir 25 ~ 35 minutes;

Medicinal liquid is sub-packed in drug-containing dish after measuring sodium bicarbonate 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 sodium bicarbonate composition lyophilizing 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 sodium bicarbonate composition lyophilizing 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 sodium bicarbonate composition lyophilizing sheet, dosage of sucrose is 8.5% (W/V), it is the hardness reinforcer of this tablet, and plays flavored action.Sodium bicarbonate composition lyophilizing sheet only needs starch and sucrose two kinds of adjuvants.The freeze-dry process of two liters falls in sodium bicarbonate composition lyophilizing 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.
