Corticorelin (Acthrel) vs Eptifibatide (Integrilin)

An educational, source-based comparison of Corticorelin (Acthrel) and Eptifibatide (Integrilin) — how each peptide works, what it's researched for, and what to know before going deeper.

CRH Analog · Diagnostics
Corticorelin (Acthrel)

Synthetic ovine CRH for differential diagnosis of Cushing's syndrome.

Mechanism

Synthetic ovine corticotropin-releasing hormone (oCRH) that stimulates pituitary ACTH release; used in inferior petrosal sinus sampling and peripheral CRH stimulation testing to distinguish pituitary from ectopic ACTH-dependent Cushing's syndrome.

Research areas
  • Differential diagnosis of ACTH-dependent Cushing's syndrome
Considerations
  • FDA-approved.
  • Transient flushing, dyspnea, hypotension possible.

Antiplatelet · Cardiology
Eptifibatide (Integrilin)

GP IIb/IIIa inhibitor cyclic peptide for ACS and PCI.

Mechanism

Cyclic heptapeptide derived from rattlesnake venom that reversibly blocks platelet glycoprotein IIb/IIIa receptors, preventing fibrinogen binding and platelet aggregation.

Research areas
  • Acute coronary syndromes
  • PCI
Considerations
  • FDA-approved.
  • Bleeding risk; renal adjustment required.
