Abstract
The invention provides a potassium chloride composition freeze-dried tablet and a preparation method thereof, and relates to the technical field of medicines and medicine production. The potassium chloride composition freeze-dried tablet is prepared from potassium chloride, starch and cane sugar. Starch and cane sugar are used as auxiliary materials, and heating process treatment is performed on the ordinary corn starch, so that the bonding and disintegration functions of starch in the tablet are improved, the formability of the tablet is improved, and the potassium chloride composition freeze-dried tablet only needs the two auxiliary materials namely starch and cane sugar. The potassium chloride composition freeze-dried tablet is prepared by the freeze-drying process that the temperature is increased and decreased for two times; the process that the temperature is increased and decreased for two times enables the formability of the tablet to be better and increases the dissolution rate of the tablet, so as to improve the bioavailability of the tablet; the tablet overcomes the defect of the common potassium chloride, is high in dissolution rate and high in bioavailability, and ensures the curative effect and the safety of the clinical medication; the varieties and the dosage of the auxiliary materials in potassium chloride are reduced.
Description
Technical field
The present invention relates to medicine and medical production technical field, be specifically related to a kind of potassium chloride composition lyophilizing sheet and preparation method thereof.
Background technology
Potassium chloride is clinical conventional electrolyte balance regulating, and clinical efficacy is definite, is widely used in clinical departments.Physical property taste is extremely salty, odorless avirulence.
Molecular formula KC l
Molecular weight 74.55
Potassium chloride tablets, indication is the hypokalemia that 1. treatment hypokalemia a variety of causes cause, as hypoalimentation, vomiting, severe diarrhea, application row potassium diuretic, low potassium familial periodic paralysis, prolonged application glucocorticoid and supplementary hypertonic glucose etc.2. prevent hypokalemia to lose potassium situation when patient exists, if especially occurred when hypokalemia endangers larger to patient (as used the patient of Folium Digitalis Purpureae medicine), need preventative supplementary potassium salt, as little, serious or chronic diarrhea, long-term taking adrenocortical hormone, mistake potassium nephropathy, the Bartter syndrome etc. of taking food.3. digitalism causes frequent, polyphyly premature beat or tachy-arrhythmia.Clinical common formulations is tablet and injection.
In common potassium chloride tablets 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 potassium chloride tablets, improve potassium chloride 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 potassium chloride 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 potassium chloride 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 potassium chloride composition lyophilizing sheet, does adjuvant with starch and sucrose, produces with freeze-dry process, this tablet overcomes the shortcoming of above-mentioned common potassium chloride tablets, decreases supplementary product kind and consumption in potassium chloride tablets, and this sheet dissolution is large, bioavailability is high, ensure that curative effect and the safety of clinical application.
A kind of potassium chloride composition lyophilizing sheet, is prepared from by following raw material:
A preparation method for potassium chloride 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 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 250 grams, potassium chloride, add in 1L Semen Maydis-sucrose solution, stir 25 ~ 35 minutes;
Medicinal liquid is sub-packed in drug-containing dish after measuring KCE 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 potassium chloride 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 potassium chloride 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 potassium chloride composition lyophilizing sheet, dosage of sucrose is 8.5% (W/V), it is the hardness reinforcer of this tablet, and plays flavored action.Potassium chloride composition lyophilizing sheet only needs starch and sucrose two kinds of adjuvants.The freeze-dry process of two liters falls in potassium chloride composition lyophilizing sheet employing two, and twice cooling, twice intensification can make sheet mouldability better, which increase the dissolution of tablet, thus improve the bioavailability of tablet.
