Abstract

The invention provides an omeprazole enteric capsule and a prepared method thereof and belongs to the field of medicinal preparation. The omeprazole enteric capsule can solve the problem that an existing omeprazole enteric capsule cannot be fully and timely released and is poor in stability after being taken orally. The omeprazole enteric capsule is composed of a pill core, an alkali layer, an isolating layer, an enteric layer and an outer layer from inside to outside in sequence. By means of the addition of the alkali layer, formula of each layer is optimized and full and timely release and stability of the omeprazole enteric capsule are guaranteed.

Description

Technical field [0001] The invention belongs to the field of pharmaceutical preparations, and specifically relates to an omeprazole enteric-coated capsule and a preparation method thereof. Background technique [0002] Omeprazole as a proton pump inhibitor has been widely used in the treatment of peptic ulcer diseases such as gastric ulcer, duodenal ulcer, reflux esophagitis, gastrinoma. [0003] Omeprazole is extremely stable under neutral and alkaline conditions with a half-life of 17 hours; but it is easily degraded in an acidic environment, and is very unstable when the pH is close to the acidity of gastric juice (pH=1), with a half-life of about 2 minutes . In addition, omeprazole is also sensitive to humidity, temperature and light, which tends to reduce its stability. In order to maintain the pharmacological activity of omeprazole after taking it, most of the omeprazole currently marketed in China is enteric-coated preparations. [0004] Enteric-coated preparations generall...
