Zopantol Tablet contains Pantoprazole 40mg, a proton pump inhibitor (PPI) used primarily for the treatment of acid-related gastrointestinal conditions. Pantoprazole acts by selectively inhibiting the H+/K+ ATPase enzyme system at the secretory surface of gastric parietal cells, thereby suppressing gastric acid secretion. Zopantol is indicated for the management of gastroesophageal reflux disease (GERD), erosive esophagitis, Zollinger-Ellison syndrome, and peptic ulcer disease, including duodenal and gastric ulcers. It is also effective in the eradication of Helicobacter pylori infection when used in combination with appropriate antibiotics. The medication provides symptomatic relief from heartburn, acid regurgitation, and epigastric pain by reducing gastric acidity, promoting mucosal healing, and preventing ulcer recurrence. Zopantol is generally well tolerated; common adverse effects include headache, diarrhea, nausea, and abdominal discomfort. It is contraindicated in patients with known hypersensitivity to Pantoprazole or other proton pump inhibitors. Dose adjustments may be necessary in patients with severe hepatic impairment. Administration is typically once daily before meals, and treatment duration depends on the specific indication and clinical response. Patients should consult healthcare providers before initiating therapy to ensure appropriate use and to discuss potential drug interactions.
