Abstract
The invention relates to chlortetracycline hydrochloride effervescent tablets. The chlortetracycline hydrochloride effervescent tablets are prepared from, by weight, 5%-30% of chlortetracycline hydrochloride, 5%-25% of tartaric acid, 5%-25% of sodium bicarbonate, 1%-15% of soluble starch, 1%-10% of microcrystalline cellulose, 1%-50% of anhydrous dextrose and 1%-30% of nicotinamide. Compared with traditional soluble chlortetracycline hydrochloride powder, the chlortetracycline hydrochloride effervescent tablet product is good in solubility, better in therapeutic effect and convenient to use, and the phenomena such as wall sticking and dust are reduced.
Description
Technical field
The invention belongs to chlortetracycline hydrochloride preparation technique field, be specifically related to formula of a kind of novel chlortetracycline hydrochloride effervescent tablet products and preparation method thereof.
Background technology
Chlortetracycline hydrochloride, calls Chlortetracycline, and the same tetracycline of its antimicrobial spectrum, to penicillin resistant, the curative effect of staphylococcus aureus is stronger than tetracycline.Now it is mainly used in treating conjunctivitis, trachoma etc..At present, chlortetracycline hydrochloride common formulations for animals on sale on market is mainly soluble powder, owing to chlortetracycline is unstable, it is prone to oxidation, variable color, stability and therapeutic effect impact on preparation are relatively big, the most urgently develop a kind of novel stabilising efficient chlortetracycline hydrochloride product.
Summary of the invention
Present invention aim to overcome that prior art defect, it is provided that a kind of novel chlortetracycline hydrochloride effervescent tablet products and preparation method thereof.
For achieving the above object, the present invention adopts the following technical scheme that
A kind of chlortetracycline hydrochloride effervescent tablet, it includes following components in percentage by weight: chlortetracycline hydrochloride 5-30%, tartaric acid 5-25%, sodium bicarbonate 5-25%, soluble starch 1-15%, microcrystalline Cellulose 1-10%, anhydrous glucose 1-50% and nicotiamide 1-30%.
The preparation method of above-mentioned chlortetracycline hydrochloride effervescent tablet, it comprises the steps:
1) raw material prepares: take each raw material in proportion, wherein soluble starch, anhydrous glucose and nicotiamide are divided into two parts, a copy of it and chlortetracycline hydrochloride, tartaric acid mix homogeneously obtain acid material, and additionally a and sodium bicarbonate mix homogeneously obtains alkaline material；
2) pelletize: above-mentioned acid material and alkaline material are separately added in granulator granulation and obtain acid particles and alkali grain, drying, sieve, take the 60 above granules of mesh standby；
3) tabletting: acid particles and alkali grain are sufficiently mixed uniformly with microcrystalline Cellulose, tablet machine tabletted, obtain chlortetracycline hydrochloride effervescent tablet finished product, available aluminium foil bag vacuum packaging.
In effervescent tablet formula of the present invention, chlortetracycline hydrochloride is that medicinal ingredient, tartaric acid and sodium bicarbonate are used as effervescent, and soluble starch is used as binding agent, and microcrystalline Cellulose is used as disintegrating agent, anhydrous glucose and nicotiamide and is used as filler；Common commercially available prod all can directly be bought by raw material in formula.Compared with traditional chlortetracycline hydrochloride soluble powder, chlortetracycline hydrochloride effervescent tablet products dissolubility of the present invention is good, therapeutic effect more preferable, and easy to use, reduces the generation being stained with the phenomenon such as wall, dust.
Compared to the prior art, beneficial effects of the present invention:
Compared to soluble powder, the characteristic of Aquatic product anger bubble met by chlortetracycline hydrochloride effervescent tablet of the present invention, can save manual stirring step, and solution is more uniform, thus play therapeutical effect larger；During preparing effervescent tablet, acid material is pelletized respectively with alkaline material, it is to avoid directly contacts, improves its stability；Tablet is stained with wall, is played the shortcomings such as dirt during can avoiding using；Fill anhydrous glucose, nicotiamide can as energy, vitamin supplement, improve curative effect.Being experimentally verified that, the chlortetracycline hydrochloride effervescent tablet therapeutic effect of the present invention is significantly better than traditional chlortetracycline hydrochloride soluble powder.
Detailed description of the invention
Below in conjunction with embodiment, technical scheme is discussed in detail further, but protection scope of the present invention is not limited thereto.
