What Teriparatide is
Teriparatide consists of residues 1 to 34 of parathyroid hormone, the part of the full-length hormone that binds and activates the PTH1 receptor. It is sold as an approved injectable medicine under several brand names.
In research it is used as the benchmark PTH1 receptor agonist. Studies often contrast intermittent with continuous receptor exposure, which produces opposite effects in bone models.
What the research literature studies
- PTH1 receptor signalling through cAMP and calcium pathways in cell models
- Bone-cell biology: osteoblast and osteoclast responses to receptor activation
- Stability and identity analysis of a 34-residue peptide hormone fragment
Evidence rating: 5/5
Approved drug, phase 3 trials. Approved medicine with randomised phase 3 trials and long post-marketing experience. See our methodology for how levels are assigned.
- Most outcome data come from the branded medicine, not from research-grade material.
- Findings from animal bone models should not be extrapolated beyond the model.
Regulatory status
Teriparatide is authorised as a prescription medicine by the MHRA, EMA and FDA under brand names. Laboratory research material is not that medicine and must not be used in people or animals.
