<p>Raloxifene is a selective estrogen receptor modulator (SERM). The biological actions of Raloxifene are largely mediated through binding to estrogen receptor. This binding results in activation of certain estrogenic pathways and blockade of others. Raloxifene reduces resorption of bone and decreases overall bone turnover. These effects on bone are manifested as reductions in the serum and urine levels of bone turnover markers. Clinical trials and data suggest that Raloxifene lacks estrogen like effects on the uterus and breast tissues. Raloxifene is rapidly absorbed after oral administration, metabolized in liver, and primarily excreted in faeces and rest in urine.</p>
