Abstract

The invention discloses a composite preparation of Omepraxole and Clarithromycin, wherein the weight ratio of the active constituents Omepraxole and Clarithromycin is 1:10-1:50, the preparation can be used for treating diseases such as Helicobacter Pylori infection.

Description

technical field [0001] The invention relates to a medicine for treating Helicobacter pylori, more specifically, the invention relates to a combined preparation of omeprazole and clarithromycin for treating Helicobacter pylori. Background technique [0002] Peptic ulcer may be caused by Helicobacter pylori (HP) infection. The ecologically suitable environment for Helicobacter pylori is human gastric epithelial cells, and other Helicobacter species reside in various animal hosts. High adaptability keeps it from being eliminated during migration, which depends on HP's movement ability and urease activity, as well as the special adhesin it produces. After HP infection, if it is not treated, it will usually persist in the host for life. [0003] Omeprazole is a proton pump inhibitor (PPI) that blocks gastric acid secretion from various causes. After PPI enters the human body, the action time can reach more than 24 hours, so the acid suppression intensity of PPI is strong and t...
