RALOXIFENE

COMMON BRAND NAME(S): Evista

GENERIC NAME(S): RALOXIFENE HCL

Description: Raloxifene is a selective oestrogen receptor modulator (SERM) that works in osteoporosis by decreasing bone breakdown and thinning that may occur in women after menopause. It works to decrease the risk of invasive breast cancer by blocking estrogen in breast and uterine tissue.

Pharmacokinetics:

Absorption: Well absorbed from the GI tract (oral).

Distribution: Protein-binding: Extensive to albumin and α1-acid glycoprotein.

Metabolism: Extensively hepatic; converted to glucuronide conjugates; undergoes enterohepatic recycling.

Excretion: Faeces; 27 hr (elimination half-life).

Uses

Raloxifene is used by women to prevent and treat bone loss (osteoporosis) after menopause. It slows down bone loss and helps to keep bones strong, making them less likely to break.

Raloxifene may also lower the chance of getting a certain type of breast cancer (invasive breast cancer) after menopause.

Raloxifene is not an estrogen hormone, but it acts like estrogen in some parts of the body, like your bones. In other parts of the body (uterus and breasts), raloxifene acts like an estrogen blocker. It does not relieve menopause symptoms such as hot flashes. Raloxifene belongs to a class of drugs known as selective estrogen receptor modulators-SERMs.

This medication should not be used before menopause.

It should not be used to prevent heart disease.
