preparation example Construction

[0034] The preparation of lansoprazole enteric-coated pellets is carried out in a fluidized bed granulation coating machine. The preparation process is coating of the main drug layer, coating of the isolation layer, coating of the neutral layer, and coating of the enteric layer;

[0035] Among them, 1) The specific operation of coating the main drug layer is as follows:

[0036] Take 20-40mL of purified water, stir, and slowly add 0.2-0.4g of anhydrous sodium carbonate as an acid-base regulator. -0.4 g polysorbate-80 is used as a solubilizer, and after dissolving completely, add lansoprazole in the dark, and stir into a uniform suspension; the blank ball core is placed in a fluidized bed granulation coating machine, and the boiling air volume 20-40 Hz, jet pressure 0.1-0.3 MPa, material temperature 35-40 ℃, spray speed 2.0-4.0 mL min -1 , the main drug layer coating pellet containing lansoprazole 20-40% is obtained;

[0037] 2) The specific operation of the isolation layer c...

Abstract

The invention relates to a compound capsule and a preparation method thereof. The capsule comprises lansoprazole enteric coated pellets, clarithromycin stomach-soluble pellets and amoxicillin stomach-soluble pellets. The compound capsule is administered twice one day based on the following dose each time: lansoprazole 20-40 mg, clarithromycin 400-600 mg, and amoxicillin 900-1100 mg. The capsule provided by the invention has a distinct effect on peptic ulcer, is used for thoroughly killing helicobacter pylori, and has the advantages of quick action, strong effect, improved bioavailability, convenience in administration and low cost.

Description

technical field [0001] The invention belongs to the field of pharmacy, and more specifically relates to a compound capsule and a preparation method thereof. Background technique [0002] Peptic ulcer (peptic ulcer) is one of clinically common and frequently-occurring diseases. my country is an area with a high incidence of ulcers, and according to statistics, about 10% of the population has suffered from this disease in their lifetime. Clinically, duodenal ulcer is more common than gastric ulcer, and the ratio of the two is about 1.56-5.6:1. Gastric ulcer and duodenal ulcer are chronic diseases with high recurrence coefficient, and require long-term treatment, especially for patients with gastric ulcer and duodenal ulcer caused by Helicobacter pylori infection. For patients, the price factor of medicines is very important. Therefore, the majority of patients urgently need products with good curative effect, high safety, low price, small adverse effects, good durability, a...
