What Is GIP?
What is GIP (glucose-dependent insulinotropic polypeptide)? How dual GIP/GLP-1 drugs like tirzepatide differ from GLP-1-only medications.
View definitionThis glossary defines the pharmacology, clinical-trial vocabulary, and insurance terminology that appears throughout glp1versus.com's discussions of GLP-1 receptor agonists. Each entry is written to stand alone: a precise definition, a note on clinical significance, and cross-links to related drugs or conditions where the term applies. Definitions reflect current FDA labeling and peer-reviewed literature as of each entry's last review date. Entries are medically reviewed by Dr. Elena Vance, DO, and are intended to help patients, caregivers, and non-specialist clinicians interpret prescribing information and clinical-trial results accurately. For definitions of specific drug brand names rather than class-level concepts, see the drug profile index at /drugs. The glossary is updated as new entries are added and as FDA labels change.
