Which drug is classified as a Proton Pump Inhibitor?

Proton Pump Inhibitors (PPIs) are a class of medications primarily used to decrease the production of stomach acid, thereby treating conditions such as gastroesophageal reflux disease (GERD), ulcers, and certain types of gastritis. Pantoprazole Sodium is an example of a proton pump inhibitor and works by inhibiting the proton pump in the stomach lining, which is responsible for secreting gastric acid.

Digoxin is a cardiac glycoside used to treat heart conditions, primarily heart failure and atrial fibrillation. Paroxetine Hydrochloride is an antidepressant belonging to the selective serotonin reuptake inhibitor (SSRI) class, used primarily to treat depression and anxiety disorders. Levetiracetam is an antiepileptic drug used to treat seizures. None of these options classify as proton pump inhibitors because they act on different mechanisms in the body and treat different conditions compared to pantoprazole.
