Cosyntropin (Cortrosyn) vs Teriparatide (Forteo)
An educational, source-based comparison of Cosyntropin (Cortrosyn) and Teriparatide (Forteo) — how each peptide works, what it's researched for, and what to know before going deeper.
Synthetic peptide containing the first 24 amino acids of ACTH — retains full corticotropic activity. Stimulates adrenal cortisol release for diagnostic testing.
- Primary and secondary adrenal insufficiency diagnosis
- • FDA-approved.
- • Single diagnostic dose; very well tolerated.
Recombinant PTH(1-34) for severe osteoporosis.
Recombinant fragment of parathyroid hormone (amino acids 1–34). Intermittent dosing stimulates osteoblast activity more than osteoclasts, producing net bone formation and increased bone mineral density.
- Postmenopausal osteoporosis
- Male osteoporosis
- Glucocorticoid-induced osteoporosis
- • FDA-approved.
- • Lifetime use limited to 2 years; transient hypercalcemia possible.
Cosyntropin (Cortrosyn) vs Teriparatide (Forteo) — Key differences
- Class: Cosyntropin (Cortrosyn) is classified as Diagnostic · Endocrine, while Teriparatide (Forteo) is Parathyroid Hormone · Anabolic Bone.
- Primary research focus: Cosyntropin (Cortrosyn) — primary and secondary adrenal insufficiency diagnosis; Teriparatide (Forteo) — postmenopausal osteoporosis.
- Tag: FDA-Approved · Diagnostic vs FDA-Approved · Bone.
