One medication that lowers stomach acid production is Pantosec Tablet. When a muscle above your stomach relaxes excessively, stomach contents and acid can reflux up into your mouth and esophagus, causing heartburn and acid reflux. Pantosec Tablet is a member of the class of medications known as proton pump inhibitors. It lessens the production of stomach acid and eases the discomfort of acid reflux and heartburn. By altering your lifestyle, you can improve the medication's effectiveness. These include eating smaller, more often meals, avoiding items that aggravate the symptoms, and, if you are overweight, decreasing weight.
