What is Raloxifene?
Raloxifene is a prescription medication mainly used to prevent and treat bone loss in postmenopausal women. It belongs to a class of drugs called Selective Estrogen Receptor Modulators (SERMs), which act like estrogen in some parts of the body, especially bones.
It helps maintain bone density and reduces the risk of fractures, especially in women after menopause.
How Does Raloxifene Work?
Raloxifene works by mimicking the beneficial effects of estrogen on bone tissue. It helps:
- Slow down bone loss
- Increase bone strength
- Reduce risk of spinal fractures
- Maintain overall bone density
At the same time, it does not stimulate breast or uterine tissue in the same way as estrogen, which helps reduce certain hormone-related risks.
Uses of Raloxifene
Raloxifene is commonly prescribed for:
- Prevention of osteoporosis in postmenopausal women
- Treatment of established osteoporosis
- Reducing risk of vertebral (spine) fractures
- Improving long-term bone strength
- In some cases, reducing risk of invasive breast cancer in high-risk women
Dosage Information
The dosage of Raloxifene depends on the patient’s condition and medical history.
- Standard dose: once daily oral tablet
