Overview

What Teriparatide is

About Teriparatide

Recombinant PTH 1-34; when given intermittently, preferentially activates osteoblasts over osteoclasts; increases bone remodeling and net bone formation; stimulates IGF-1 in bone

Teriparatide (PTH(1-34); Forteo) is a synthetic 34-amino-acid peptide corresponding to the biologically active N-terminal fragment of endogenous parathyroid hormone, developed as the first FDA-approved anabolic bone agent for osteoporosis — a compound that stimulates new bone formation rather than merely inhibiting bone resorption. Teriparatide activates the PTH/PTHrP receptor (PTH1R) on osteoblasts; when administered as intermittent pulsatile subcutaneous injections, it drives net bone formation by stimulating osteoblast activity, increasing bone mineral density, improving trabecular microarchitecture, and reducing fracture risk — a distinct mechanism from antiresorptive agents such as bisphosphonates. A comprehensive systematic review and network meta-analysis published in the Annals of Internal Medicine (2023), integrating multiple randomized controlled trials, established teriparatide among the most effective pharmacological interventions for fracture prevention in osteoporosis, with significant reductions in vertebral and non-vertebral fracture risk versus placebo. Teriparatide (Forteo, Eli Lilly) is FDA-approved and requires a prescription; it is indicated for postmenopausal women, men with osteoporosis, and glucocorticoid-induced osteoporosis at high fracture risk, with a maximum treatment duration of two years due to preclinical osteosarcoma findings; biosimilar teriparatide preparations are available in multiple international markets.

  • The impact of parathyroid hormone supplementation on dental implant osseointegration in osteoporotic subjects: A systematic review.

    J Oral Biosci · 2026

    # Summary Research found that parathyroid hormone (teriparatide) supplementation consistently improved dental implant integration and peri-implant bone quality in preclinical osteoporotic animal models, with combination treatment approaches showing superior results compared to hormone therapy alone. This study demonstrated that while preclinical evidence supports PTH's potential as an adjunctive strategy to enhance implant outcomes in osteoporotic patients, significant variations in experimental methodologies currently prevent drawing definitive clinical conclusions, necessitating standardized human trials before clinical application.

    This American College of Physicians network meta-analysis found that teriparatide reduced both clinical and radiographic vertebral fractures in postmenopausal women with osteoporosis and may be more effective than bisphosphonate therapy in very high-risk patients, supporting its established role as an anabolic bone-forming peptide hormone for severe osteoporosis management.

    # Summary This study demonstrated that among osteoporotic adults undergoing lumbosacral fusion, teriparatide showed no significant association with sacral fracture risk in the two-year postoperative period. Researchers observed that vitamin D use was associated with reduced fracture risk, while a history of falls emerged as the strongest predictor of postoperative sacral fracture complications.
