Study Notes
Teriparatide (Forteo) Injection Overview
- Teriparatide, branded as Forteo, is classified as a hormone therapy.
- It functions as an exogenous parathyroid hormone (PTH) that enhances bone formation at low doses.
Indications for Use
- Approved for treating osteoporosis in postmenopausal women at high fracture risk.
- Increases bone mass in men with primary or hypogonadal osteoporosis who are at high risk for fractures.
- Treats glucocorticoid-induced osteoporosis in both men and women who are at high risk for fractures.
- Especially beneficial for patients who have failed or are intolerant to other osteoporosis treatments.
Mechanism of Action
- Regulates calcium and phosphate metabolism by binding to specific receptors, stimulating osteoblastic activity.
- Raises serum calcium levels while lowering serum phosphorus concentrations.
- Therapeutic effects include increased bone mineral density and reduced fracture risk.
Pharmacokinetics
- Absorption: Well-absorbed via subcutaneous administration.
- Metabolism: Occurs in the liver, with renal excretion of metabolites.
- Half-life: Approximately 1 hour following subcutaneous use.
- Time/Action Profile:
- Onset: 2 hours
- Peak: 4-6 hours
- Duration: 16-24 hours
Contraindications
- Hypersensitivity reactions.
- Paget's disease or any other metabolic bone disorders.
- Unexplained elevation in alkaline phosphatase levels.
- Safety and efficacy not established for pediatric patients.
- Patients with a history of radiation therapy, bone metastases, or skeletal malignancy.
- Pre-existing hypercalcemia, pregnancy, or lactation.
Cautions and Interactions
- Caution advised for patients with active or recent urolithiasis.
- Transient hypercalcemia may elevate the risk of digoxin toxicity.
Patient Education and Administration
- Administer injections at the same time each day.
- If a dose is missed, take it as soon as remembered within the same day; do not double doses.
- Patients should be trained on proper injection technique and how to dispose of needles safely.
- Emphasize reading therapeutic guides and medication manuals prior to and during therapy.
- Discard pen devices after a 28-day usage period; sharing is prohibited.
- Additional treatment strategies for osteoporosis include supplemental calcium, vitamin D, and weight-bearing exercises.
- Patients might experience orthostatic hypotension upon initial doses; recommend lying down if light-headedness occurs.
- Persistent hypercalcemia symptoms (nausea, vomiting, constipation, muscle weakness) should be reported to healthcare providers.
- Importance of follow-up bone mineral density tests should be stressed.
