Teriparatide
AFDA ApprovedParathyroid hormone analog (1-34) · 34 amino acids · Brand: Forteo, Bonsity
Teriparatide is a recombinant human parathyroid hormone analog (PTH 1-34) and the first anabolic (bone-building) agent approved by the FDA for osteoporosis. Unlike bisphosphonates which suppress bone resorption, teriparatide stimulates osteoblast activity and new bone formation.
Mechanism of Action
Mimics endogenous PTH, binding to PTH1 receptors on osteoblasts to stimulate bone formation. At intermittent (once-daily) dosing, the net effect is anabolic: increased bone mineral density, improved bone microarchitecture, and reduced fracture risk. Continuous PTH exposure is catabolic; the intermittent pulse is key.
Benefits
Side Effects
- Nausea, dizziness, leg cramps
- Hypercalcemia (transient, dose-dependent)
- Injection site reactions
- Osteosarcoma risk in rats (black box warning; limit human use to 2 years)
- Contraindicated in patients with bone metastases or skeletal malignancy
