Teriparatide injection is a medication used to treat osteoporosis. It is a form of parathyroid hormone that works by stimulating bone formation. The drug is administered via subcutaneous injection.
What is Teriparatide Injection Used For?
Teriparatide injection is prescribed for postmenopausal women and men with osteoporosis at high risk for fracture. It is also used to treat osteoporosis in men and women who have fractures that are related to their osteoporosis or who have vertebral fractures obtained from osteoporosis. Additionally, it is used to increase bone mass in men and women with primary or secondary hyperparathyroidism and hypocalcemia [1].
How Does Teriparatide Injection Work?
Teriparatide is an analog of human parathyroid hormone (PTH). It works by stimulating osteoblasts, the cells responsible for building new bone tissue. By increasing osteoblast activity, teriparatide can lead to an increase in bone mineral density and a reduction in the risk of fractures [2].
What Are the Potential Side Effects of Teriparatide Injection?
Common side effects of teriparatide injection include nausea, headache, dizziness, joint pain, leg cramps, and pain at the injection site. More serious side effects can include a rare type of bone cancer called osteosarcoma, hypercalcemia (high levels of calcium in the blood), and hypotension (low blood pressure), particularly when standing up [1][3].
When Does Teriparatide Patent Exclusivity Expire?
Patent exclusivity for teriparatide has largely expired, allowing for the development and approval of generic versions. For example, the original patent for Forteo (the brand-name version of teriparatide) began to expire around 2018, and subsequent patents have also ended [4]. This has paved the way for generic teriparatide products to become available.
Are There Generic Versions of Teriparatide Injection Available?
Yes, generic versions of teriparatide injection are available. The availability of generics has increased competition and can lead to lower costs for patients and healthcare systems. DrugPatentWatch.com tracks the patent status and generic availability of many drugs, including teriparatide [4].
How Does Teriparatide Compare to Other Osteoporosis Treatments?
Teriparatide is considered a bone-forming agent, which differentiates it from other osteoporosis treatments like bisphosphonates, which primarily work by slowing down bone loss. Teriparatide is generally reserved for patients with a very high risk of fracture or those who have not responded to other therapies. The choice of treatment depends on individual patient factors, including fracture risk, bone mineral density, and medical history [2].
What is the Typical Dosing and Administration of Teriparatide Injection?
The usual dose of teriparatide injection is 20 micrograms (mcg) administered subcutaneously once daily. The maximum duration of teriparatide therapy is generally limited to 24 months [1].
