Pantex 20 mg is a proton pump inhibitor (PPI) that contains Pantoprazole Sodium as its active ingredient. It is used to reduce stomach acid and treat conditions like gastroesophageal reflux disease (GERD), peptic ulcers, and acid reflux. It works by inhibiting the proton pumps in the stomach, thus reducing acid production. The tablet is taken once daily, preferably in the morning, and should be swallowed whole.
