Action of Somac Tablets (20mg or 40mg on Prescription):
The active ingredient in Somac 40 mg tablets is pantoprazole, which belongs to a group of medications known as proton pump inhibitors. These medications control an enzyme called H+/K+-ATPase which produces gastric acid in the parietal cells of the stomach. By controlling this enzyme, pantoprazole decreases the amount of acid produced by the stomach. When acid production is controlled, symptoms like acid reflux and stomach lesions caused by excessive acid production are also controlled.
