rabeprazole + colloidal pectin bismuth + amoxicillin + clarithromycin

This appears to be a quadruple therapy regimen used for Helicobacter pylori (H. pylori) eradication. The combination includes a proton pump inhibitor (rabeprazole), a bismuth compound (colloidal pectin bismuth), and two antibiotics (amoxicillin and clarithromycin). ## Description This is a bismuth-containing quadruple therapy used for the eradication of Helicobacter pylori infection. The combination works through multiple mechanisms: - Rabeprazole reduces stomach acid production, creating a less acidic environment that inhibits H. pylori growth and enhances antibiotic efficacy[4][10] - Bismuth compounds have direct antimicrobial effects against H. pylori and help prevent antibiotic resistance[5][8] - Amoxicillin disrupts bacterial cell wall synthesis[4][6] - Clarithromycin inhibits bacterial protein synthesis[4][6] This combination is particularly valuable in areas with high antibiotic resistance rates, as the bismuth component helps overcome resistance issues. Clinical trials have shown high eradication rates with this type of quadruple therapy, typically administered for 10-14 days[1][6].
