Drug Entry
Raloxifene

Raloxifene is a second generation selective estrogen receptor modulator (SERM) that mediates anti-estrogenic effects on breast and uterine tissues, and estrogenic effects on bone, lipid metabolism, and blood coagulation.6,12 Exhibiting tissue-specific effects distinct from estradiol, raloxifene is the first of the benzothiophene group of antiestrogens to be labelled a SERM.7 Available in many countries worldwide, raloxifene was initially approved by the FDA in December, 1997 under the market name Evista® for the management and prevention of osteoporosis in postmenopausal women and reduction in risk for invasive breast cancer in postmenopausal women with osteoporosis or those who are at high risk for invasive breast cancer. However, it has a negligible effect on altering the development and progression of breast cancer itself.Label The most common causes of osteoporosis include postmenopausal deficiency of estrogen and age-related deterioration in bone homeostasis. Due to the risk of bone fractures that may lead to morbidities and reduced quality of life, the management of osteoporosis in postmenopausal women with the use of therapeutic agents in addition to concurrent therapies is critical. Due to the decline in estrogen levels in postmenopausal osteoporosis, hormone replacement therapy (HRT), such as estradiol, has been used to ameliorate the condition. However, due to the off-target actions by HRT, newer non-hormonal agents such as raloxifene and tamoxifen have been developed to reduce adverse events through selective pharmacological actions on tissue-specific therapeutic targets.12

The main effects of raloxifene are to preserve the bone mineral density and decrease the risk of breast cancer in postmenopausal women. Compared to estrogen and tamoxifen, raloxifene was not associated with an increased risk of uterine cancer and it does not cause endometrial proliferation.1 Although rare, there was an increased risk of venous thromboembolism during clinical trials of postmenopausal women receiving raloxifene. In addition, a clinical study consisting of postmenopausal women with documented coronary heart disease or at increased risk for coronary events showed an increased risk for fatal stroke with raloxifene therapy compared to placebo.Label It is strongly advised that the risk-benefit ratio is considered before starting raloxifene therapy in women at risk of thromboembolic disease or strokes, such as the prior history of stroke, transient ischemic attack, atrial fibrillation, hypertension, or cigarette smoking.Label
