Zoreso Tablet contains Esomeprazole 40 mg, a proton pump inhibitor (PPI) used primarily to reduce gastric acid secretion. It is indicated for the treatment of gastroesophageal reflux disease (GERD), erosive esophagitis, Zollinger-Ellison syndrome, and for the prevention and treatment of gastric ulcers associated with Helicobacter pylori infection or nonsteroidal anti-inflammatory drug (NSAID) use. Esomeprazole works by selectively inhibiting the H+/K+ ATPase enzyme system at the secretory surface of gastric parietal cells, thereby suppressing the final step of acid production. This results in a significant reduction of gastric acidity, promoting healing of acid-related damage and alleviating symptoms such as heartburn and acid regurgitation. Zoreso Tablet is typically administered orally once daily, preferably before meals, with dosage adjustments based on clinical response and specific indications. It is generally well tolerated, with common adverse effects including headache, diarrhea, nausea, and abdominal discomfort. Caution is advised in patients with hepatic impairment, and long-term use should be monitored due to potential risks such as vitamin B12 deficiency, hypomagnesemia, and increased susceptibility to gastrointestinal infections. Zoreso Tablet should be used under medical supervision to ensure optimal therapeutic outcomes and safety.
