proton pump inhibitor

This term is a technical medical designation used primarily in clinical settings, pharmacology, and patient consultations. It describes a specific class of drugs, such as omeprazole or lansoprazole, characterized by their high potency in suppressing gastric acid secretion compared to older treatments like H2 blockers.

In professional medical shorthand, this term is frequently abbreviated as PPI. While the full phrase is used in formal prescriptions and academic literature, the abbreviation is standard in both clinical notes and patient-facing healthcare communications.
