Problems solved by technology

Disadvantages of this method: acarbose has poor fluidity, even if lubricant is added, its fluidity cannot be improved well, and the main drug and auxiliary materials are mixed and pressed into tablets. The raw material of acarbose is relatively light, and the auxiliary materials After mixing directly, and then compressing the tablets, there will be large differences in the tablets, and even unqualified phenomena, and powder spraying will occur during the tableting process, which cannot guarantee the eligibility of the tablet weight
The effect of wet granulation and high-speed stirring granulation is not good, it is easy to cause unqualified tablet quality after tableting, and it is difficult to sieve and granulate.

Abstract

The invention discloses acarbose tablets and a preparation method thereof. The preparation method comprises the following steps of: uniformly mixing acarbose, microcrystalline cellulose, starch and 2 / 3 of carboxymethyl starch sodium to form a premix; pelletizing and granulating the premix through a dry process to obtain particles; and uniformly mixing the particles, 1 / 3 of carboxymethyl starch sodium, magnesium stearate and silicon dioxide, tabletting the mixture by a tablet press to obtain the acarbose tablets. According to the tablets prepared by dry-process palletizing and tabletting methods, the hardness and stability of the tablets are effectively improved and the problems of unaccepted disintegration time and unaccepted microorganisms are solved; as a result, the quality of the tablets is improved; and besides, the preparation method is simple in process flow, capable of saving energy source and cost, and suitable for industrial production.

Description

technical field [0001] The invention relates to the field of pharmaceutical preparations, in particular to an acarbose tablet and a preparation method thereof. Background technique [0002] Diabetes Mellitus (DM) is a group of metabolic diseases characterized by chronic elevated blood glucose (referred to as blood sugar) levels, which is caused by defects in insulin secretion and / or action. Long-term carbohydrate, fat, and protein metabolic disorders can cause multi-system damage, leading to chronic progressive lesions, functional decline, and failure of tissues and organs such as eyes, kidneys, nerves, heart, and blood vessels. Severe metabolic disorders can occur in severe illness or stress, such as diabetic ketoacidosis (DKA), hyperglycemia and hyperosmolar state, etc. The disease reduces the quality of life of patients, shortens the life expectancy, and increases the mortality rate. It has become the third largest non-communicable disease that seriously endangers human ...
