It is prescribed to treat acid-related stomach and intestinal ailments such as heartburn, acid reflux, peptic ulcer disease, and Zollinger-Ellison syndrome. Heartburn and acid reflux occur when a muscle above your stomach relaxes too much, allowing stomach contents and acid to flow back into your esophagus and mouth. Pentaloc 40 Tablet belongs to a class of medications known as proton pump inhibitors. It decreases stomach acid production and alleviates the pain associated with heartburn and acid reflux. Making some lifestyle adjustments can help to improve the effectiveness of the drug. These include avoiding foods that cause the symptoms, eating smaller, more often meals, and decreasing weight if you are overweight.
