Evista is used to treat and prevent osteoporosis

 

Evista is indicated for the treatment and prevention of osteoporosis in postmenopausal women. A significant reduction in the incidence of vertebral, but not hip fractures has been demonstrated.

When determining the choice of Evista or other therapies, including oestrogens, for an individual postmenopausal woman, consideration should be given to menopausal symptoms, effects on uterine and breast tissues, and cardiovascular risks and benefits.

Mechanism of Action

Evista is an estrogen agonist/antagonist, referred to as a selective estrogen receptor modulator (SERM) and belongs to the benzothiophene class of compounds. The biological actions of raloxifene are largely mediated through binding to estrogen receptors. This binding results in activation of estrogenic pathways in some tissues (agonism) and and the blockade of estrogenic pathways in other tissues (antagonism). The agonistic or antagonistic activity of raloxiffene depends on the extent of recruitment of coactivators and corepressors to estrogen receptor (ER) target gene promotors. Raloxifene appears to act as an estrogen agonist in bone. It decreases bone resorption and bone turnover, increases bone mineral density and decreases fracture incidence.
