The present invention relates to a pharmaceutical composition and its preparation method for the eradication of Helicobacter pylori in the forms of effervescent tablet, suspension or powder. The pharmaceutical composition comprises an effective dose of β-lactam antibiotic, an effective dose of macrolide antibiotic, an effective dose of antacid such as proton pump inhibitor and H2 blocker, and a pharmaceutical acceptable carrier. An effective dose of alkaline substance such as carbonate or bicarbonate can be added to increase the pH of the stomach when the PPI antacid is used, which can protect the degradation of acid-labile antibiotics or PPI to further increase the bioavailability of the pharmaceutical composition for the purpose of Helicobacter pylori eradication.
