Junior Lanzol 15mg Tablet DT contains Lansoprazole, a proton pump inhibitor (PPI) used to treat conditions related to excessive stomach acid, such as gastroesophageal reflux disease (GERD), peptic ulcers, and Zollinger-Ellison syndrome. Lansoprazole works by blocking the proton pumps in the stomach lining, reducing acid production and alleviating symptoms like heartburn, acid reflux, and stomach pain. The "DT" stands for "dispersible tablet," which is designed to dissolve easily in water, making it suitable for children and individuals who may have difficulty swallowing tablets. Common side effects can include nausea, diarrhea, and abdominal pain. It is important to follow the prescribed dosage and consult a healthcare provider if symptoms persist or if any severe side effects occur.
