Proton-pump inhibitor

A Proton-pump inhibitor (PPI) is a type of drug that reduces the production of stomach acid by blocking the enzyme in the wall of the stomach that produces acid. The reduction of acid prevents ulcers and allows any ulcers that exist in the esophagus, stomach, and duodenum to heal.

Pronunciation

Proton-pump inhibitor: /ˈproʊtɒn pʌmp ɪnˈhɪbɪtər/

Etymology

The term "Proton-pump inhibitor" is derived from its function. A "proton pump" is an integral membrane protein that is capable of moving protons across a biological membrane. An "inhibitor" is a substance that slows down or prevents a particular chemical reaction or other processes.
