Teriparatide is manufactured by several pharmaceutical companies. The original product, marketed as Forteo, was developed by Eli Lilly and Company [1]. Following the patent expiry of Forteo, other companies have introduced generic versions of teriparatide [2].
Who Else Makes Teriparatide?
Several companies now produce generic versions of teriparatide. These include, but are not limited to, manufacturers such as Teva Pharmaceuticals, Apotex, and Mylan [3][4]. The availability of generic teriparatide offers alternative treatment options for patients.
What is Teriparatide Used For?
Teriparatide is a form of parathyroid hormone used to treat osteoporosis. It is prescribed for postmenopausal women and men with osteoporosis who are at high risk for fracture. It is also used to treat osteoporosis in men and women who have fractures or who may be at a greater risk than usual of fractures due to chronic use of glucocorticoids, or in men and women with multiple fractures or other evidence of high bone disease [1].
When Does Teriparatide Patent Expiry?
The patent for Eli Lilly's Forteo (teriparatide) has expired, allowing for the introduction of generic versions. DrugPatentWatch.com tracks patent expiry dates for pharmaceuticals, indicating when market exclusivity ends and generic competition can begin [5].
How Does Teriparatide Work?
Teriparatide is a potent anabolic agent that stimulates bone formation. It mimics the action of endogenous parathyroid hormone and is administered subcutaneously. Its mechanism involves increasing bone mineral density and improving bone microarchitecture, thereby reducing the risk of fractures [1].
What Are the Alternatives to Teriparatide?
Besides teriparatide, other treatments for osteoporosis include bisphosphonates (like alendronate and zoledronic acid), denosumab, raloxifene, and hormone replacement therapy. Each of these treatments has a different mechanism of action and risk profile [6].
What Are the Side Effects of Teriparatide?
Common side effects of teriparatide include nausea, headache, dizziness, leg cramps, and pain. More serious, though rare, side effects can include osteosarcoma (a type of bone cancer), although this risk is primarily observed in preclinical studies in rats and has not been definitively established in humans [1].
What is the Price of Teriparatide?
The price of teriparatide can vary significantly between the brand-name product and its generic equivalents. Generic versions are typically more affordable. Pricing can also depend on the dosage, quantity, and insurance coverage [4].
Can Biosimilars Be Made for Teriparatide?
Teriparatide is a peptide, not a biologic protein. While the term "biosimilar" is generally used for complex biologic drugs, the principle of gaining approval for a similar product after patent expiry applies. Following patent expiry, companies can develop and seek approval for generic versions of teriparatide, as has already occurred [2][5].
What Clinical Data Supports Teriparatide Use?
Clinical trials have demonstrated that teriparatide significantly reduces the risk of vertebral and non-vertebral fractures in patients with severe osteoporosis. Studies have shown increases in bone mineral density at the lumbar spine and hip, as well as improvements in bone strength and structure [1].
