preparation example Construction

[0016] The application of the hydroxyaluminum montmorillonite of the present invention in the preparation of antacids, the preparation method of the antacids, the steps are as follows:

[0017] (1) Soak the montmorillonite clay in purified water for 1-2 hours under stirring, and then use a sand mill or colloid mill for liquid crushing to obtain a suspension; let it stand for 6-8 hours; remove the sedimentation liquid, and mix the upper layer The suspension was centrifuged in a decanter centrifuge, and the collected relative density was 2.0-2.2g / cm 3 After passing through a 120-160 mesh sieve, the feed liquid is acidified with a hydrochloric acid solution with a concentration of 1-3N, and the temperature of the acidification process is controlled at a temperature of 10-70°C; stir for 1-3 hours until the pH of the liquid is 1.5-3.5 Then separate with a centrifuge, and the filter cake is repeatedly washed with purified water until the pH value is neutral after washing; then, the ...

[0038] Experimental example 1: Experimental research on the influence of time and concentration of montmorillonite in hydrochloric acid solution

[0039] Raw materials: montmorillonite, hydrochloric acid;

[0040] Add 5 pieces of 80mL 3N hydrochloric acid solution into the Erlenmeyer flask, cover it and place it in a shaker, keep the temperature at 70±2°C, and then add 1.0g of pure montmorillonite sample respectively. The capped bottle stopper was shaken at a constant temperature of 120r / min for a certain period of time (0h, 3h, 12h, 24h, 36h), and after taking it out, it was centrifuged with a desktop centrifuge (maximum speed 6000r / min), and the supernatant was taken and spectrophotometrically Determination of the concentration of aluminum ions in the dissolution solution and calculation of AL 2 o 3 Dissolution rate. AL 2 o 3 Dissolution rate of Al 2 o 3 The ratio of dissolved mass to initial mass. The residue after centrifugation was repeatedly washed with distilled...

[0051] Experimental example 2: Activation experiment of montmorillonite in hydrochloric acid solution

[0052] Raw materials: montmorillonite, hydrochloric acid;

[0053] Weigh 5g of ground montmorillonite sample and pour it into a 250ml Erlenmeyer flask; add 200ml of hydrochloric acid (concentrations are 1.0N, 1.5N and 3.0N respectively), bathe in water at 70±2°C for 3h; filter and wash repeatedly with deionized water to pH ≈6, 1O0 ℃ drying after standby, XRD and SEM analysis of the sample after acid treatment.

[0054] (1) XRD analysis

[0055] The above montmorillonite treated with hydrochloric acid is consistent with the XRD patterns of montmorillonite activated without hydrochloric acid and with different concentrations of 1.0N, 1.5N, 3.0N hydrochloric acid;

[0056] Montmorillonite has a higher degree of crystallization and fewer active sites that can react with hydrochloric acid. After activation by hydrochloric acid, the activity was significantly improved, indicati...

Abstract

The invention discloses an application of hydroxyaluminum montmorillonite in preparing antacid. The drug active ingredient of the antacid is hydroxyaluminum montmorillonite, and the mass percentage of hydroxyaluminum montmorillonite in the medicine is 50% to 100%; the rest are pharmaceutical excipients; the hydroxyaluminum montmorillonite is Soaking or eluting with acid solution and separating montmorillonite, then soaking or eluting with sodium hydroxide solution, modifying by aluminum hydroxide gel, then separating hydroxyaluminum montmorillonite, and activating under high temperature conditions owned. The present invention is administered through the gastrointestinal tract, so that the active ingredients can neutralize the pH value of the patient's gastric juice and reduce the activity of pepsin, so it can relieve gastric pain and promote the healing of gastric ulcer, and then be excreted through the digestive tract to achieve anti-inflammatory effect. The purpose of stomach acid.

Description

technical field [0001] The present invention relates to the use of hydroxyaluminum montmorillonite, and further relates to the use of said hydroxyaluminum montmorillonite in the preparation of antacids for treating conditions or diseases associated with harmful gastric acid levels. Background technique [0002] The human stomach secretes substances such as gastric acid and pepsin to help it digest food. However, these substances (we call them attack factors) can also damage the mucosa in the stomach and intestines and cause ulcers, that is, erosion of the gastrointestinal mucosa. Complications such as perforation and bleeding may also occur. Normally, the stomach and intestines are well equipped to protect themselves from gastric acid and pepsin. This balance is very important to maintain a healthy digestive system, but this balance is easily broken, either due to excessive gastric acid secretion, or due to weakened gastric mucosal protective function, gastric acid invades ...
