Question

Raloxifene

Q33 marksShort Notes

Answer

Raloxifene is a selective oestrogen receptor modulator (SERM).

Mechanism of action

  • Acts as an oestrogen agonist on bone (reduces osteoclastic bone resorption) and lipid metabolism
  • Acts as an oestrogen antagonist on breast and endometrial tissue (unlike tamoxifen, which has partial agonist activity on the endometrium)

Uses

  • Prevention and treatment of postmenopausal osteoporosis
  • Reduction of risk of invasive breast cancer in high-risk postmenopausal women

Adverse effects

  • Hot flushes
  • Venous thromboembolism (similar risk to oestrogen)
  • Leg cramps
  • Does NOT increase risk of endometrial cancer (advantage over tamoxifen)
