Linaclotide (Linzess) vs Teriparatide (Forteo)

An educational, source-based comparison of Linaclotide (Linzess) and Teriparatide (Forteo) — how each peptide works, what it's researched for, and what to know before going deeper.

GC-C Agonist · Gastrointestinal
Linaclotide (Linzess)

Guanylate cyclase-C agonist peptide for IBS-C and chronic constipation.

Mechanism

14-amino-acid peptide that activates intestinal guanylate cyclase-C, increasing cGMP and chloride/bicarbonate secretion into the gut lumen — accelerating transit and reducing visceral pain.

Research areas
  • IBS-C
  • Chronic idiopathic constipation
  • Functional constipation in children
Considerations
  • FDA-approved.
  • Contraindicated in children <2 years; diarrhea common.

Parathyroid Hormone · Anabolic Bone
Teriparatide (Forteo)

Recombinant PTH(1-34) for severe osteoporosis.

Mechanism

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.

Research areas
  • Postmenopausal osteoporosis
  • Male osteoporosis
  • Glucocorticoid-induced osteoporosis
Considerations
  • FDA-approved.
  • Lifetime use limited to 2 years; transient hypercalcemia possible.
