Abstract

The invention relates to hydrotalcite preparation with rapid efficiency and a preparation process thereof, which belong to the biopharmaceuticals field. Every 1000 hydrotalcite units of the invention comprise the following constituents: 0.45-0.55kg of hydrotalcite, 0.18-0.25kg of mannitol, 12-18g of carboxymethyl starch sodium, 8.0-15.0g of magnesium stearate, 0.5-1.0g of sodium cyclamate, 0.3-0.9ml of peppermint flavor, 0.378kg-0.462kg of pre-gelatinized starch paste (12 percent by mass specific concentration) and 0.504kg-0.616kg of pre-gelatinized starch paste (5 percent by mass specific concentration). The preparation process of the invention comprises the following steps: hydrotalcite and mannitol are prepared into super-fine powder with grain diameter of 5-15um, which are blended with carboxymethyl starch sodium, sodium cyclamate and pre-gelatinized starch paste, wet granulated, sieved by a sieve with 12-16 meshes, totally mixed, packaged or tabletted to prepare finished product of hydrotalcite preparation; the hydrotalcite preparation prepared by adopting the method of the invention has fast effectiveness, good effect with low toxicity, small side-effects, pleasant taste and high suffer compliance, which is an ideal clinical antiacid.

Description

technical field [0001] The invention relates to an antacid drug for treating gastric diseases, in particular to a rapidly effective aluminum magnesium carbonate preparation and a preparation method thereof. Background technique [0002] Aluminum magnesium carbonate is a natural mineral whose structural formula is AI 2 Mg 6 (OH) 16 CO 3 4H 2 O; the chemical name is hexadecyl hydroxy dialuminum hexamagnesium carbonate tetrahydrate. It was first discovered in 1942 by Feitknecht et al. In the process of studying its structure and properties, people have found that aluminum magnesium carbonate has many excellent properties, such as being a high-efficiency, low-toxic, and smoke-free material as a flame retardant, but the most extensive and main use is as a new Antacids are used to treat gastric ulcer, duodenal ulcer, hyperacidity and gastritis, etc. It was first developed by Shionogi Pharmaceutical Company in Japan and launched in 1970. It is currently produced in Japan, th...
