Pentropazole is a medication primarily used as a proton pump inhibitor (PPI) to reduce stomach acid production. It is typically prescribed for conditions such as gastroesophageal reflux disease (GERD) and peptic ulcers. By inhibiting the proton pumps in the stomach lining, it helps alleviate symptoms related to excessive acidity. As with other PPIs, it is important to use pentropazole under medical supervision to manage potential side effects and interactions.
