Introduction to Forteo (Teriparatide Injection)

Overview of Forteo

Forte, containing teriparatide as the main ingredient, is a biologic treatment created to address osteoporosis by promoting bone growth. This injectable drug has changed the way high fracture risk patients are cared for significantly in various age groups.

Historical Development and FDA Approval Timeline

Teriparatide emerged from groundbreaking studies on parathyroid hormone analogues. Received FDA authorization in 2002. It has become a treatment for managing osteoporosis over time thanks to ongoing monitoring and research confirming its effectiveness and safety record.

Importance of Forteo in Osteoporosis Treatment

Unlike traditional antiresorptive treatments that merely slow bone loss, Forteo actively promotes new bone synthesis, enhancing bone quality and structural integrity. It is especially critical for individuals with severe osteoporosis or those who have failed previous treatments.

How Forteo (Teriparatide Injection) Works

Forteo mechanism of action

Forteois is designed to work with parathyroid hormone by encouraging bone-building activity and supporting the creation of fresh bone material. This periodic stimulation encourages bone development of breakdown.


Pharmacodynamics and Pharmacokinetics

  • Onset of Action: Increases in bone formation markers observed within weeks.
  • Absorption: Rapidly absorbed subcutaneously, reaching peak concentrations in 30 minutes.
  • Elimination: Cleared via hepatic metabolism with a half-life of approximately 1 hour.

Comparison with Other Osteoporosis Treatments

While bisphosphonates and selective estrogen receptor modulators inhibit bone resorption, Forteo uniquely builds new bone, offering a potent alternative for high-risk patients. Its anabolic action fills a crucial gap in osteoporosis therapy algorithms.

Forteo uses

Forteo for osteoporosis in Postmenopausal Women at High Fracture Risk

Forteois is prescribed for women who have gone through menopause and suffer from osteoporosis and are at risk of fractures – those with risk factors or prior osteoporotic fractures.


Osteoporosis in Men with Primary or Hypogonadal Osteoporosis at High Fracture Risk

Men who have osteoporosis or osteoporosis due to hypogonadism experience improvements from Forteo's ability to strengthen bones.


Glucocorticoid-Induced Osteoporosis

Chronic corticosteroid therapy weakens bones; Forteo is a preferred treatment to restore bone density in such individuals.

Treatment of Osteoporosis Associated with Long-Term Corticosteroid Use

Forte strengthens the bones of patients who need to take corticosteroids for conditions, helping to minimize any negative effects on their skeletal system caused by these medications.

Off-Label Uses of Forteo (Teriparatide Injection)

Fracture Healing Acceleration

Emerging evidence supports the use of Forteo to speed healing of difficult or delayed fractures, although not formally approved for this indication.


Osteogenesis Imperfecta Management

Among adults diagnosed with osteogenesis imperfecta disease or brittle bone disease, Forteo may improve bone density and decrease the risk of fractures happening.

Chronic Hypoparathyroidism

Teriparatide offers a physiological replacement option in some patients with hypoparathyroidism unresponsive to conventional therapy.

Atypical Femoral Fracture Recovery Support

Forteo has been utilized to promote healing in patients suffering from rare atypical femoral fractures, often associated with long-term bisphosphonate use.
