Prolia is a prescription medicine used to treat osteoporosis in postmenopausal women and in men who are at high risk of fractures. It is produced by Amgen Inc. and was approved by the U.S. Food and Drug Administration (FDA) on June 1, 2010. Since then, it has gained widespread use and recognition for its effectiveness in reducing the risk of fractures and improving bone density. In this article, we will explore the key points about Prolia that individuals should be aware of.
1. Mechanism of Action
Prolia is a monoclonal antibody that inhibits the activity of osteoclasts, the cells responsible for breaking down bone tissue. By inhibiting osteoclasts, Prolia helps to increase bone mass and reduce the risk of fractures.
2. Administration and Dosage
Prolia is administered as an injection under the skin (subcutaneous) every six months. The recommended dosage is 60 mg.
3. Effectiveness
Clinical trials have shown that Prolia significantly reduces the risk of vertebral, non-vertebral, and hip fractures in postmenopausal women with osteoporosis. It also increases bone mineral density in various skeletal sites.
4. Potential Side Effects
Common side effects of Prolia include back pain, muscle pain, high cholesterol levels, urinary tract infections, and skin reactions at the injection site. Rare but severe side effects may include osteonecrosis of the jaw and atypical femoral fractures.
5. Precautions
Prolia should not be used in individuals with low blood calcium levels or hypersensitivity to any of its components. It is not recommended for use during pregnancy or breastfeeding. Patients with certain medical conditions, such as compromised immune systems or dental problems, should also exercise caution.
