bismuth tripotassium dicitrate + pantoprazole

**Bismuth tripotassium dicitrate + pantoprazole** is a fixed-dose combination of two agents used in the management of acid-related gastrointestinal disorders and in multi-drug regimens for the eradication of *Helicobacter pylori* infection. - **Bismuth tripotassium dicitrate** is a bismuth salt that exhibits gastroprotective, antibacterial (notably against *H. pylori*), and mucosal barrier-enhancing effects within the GI tract. - **Pantoprazole** is a proton pump inhibitor (PPI) that irreversibly inhibits the gastric H+/K+ ATPase enzyme (the proton pump) on stomach parietal cells, suppressing gastric acid secretion for up to 24 hours. The combination is primarily used as a part of quadruple therapy for *H. pylori* eradication, often alongside antibiotics. By combining an acid suppressant and a mucosal protective agent, this regimen both improves eradication effectiveness and reduces gastric mucosal injury[1][2][4][6].
