1 OBJECTIVE: To assess and compare the effect of conjugated estrogen and of the selective estrogen receptor modulator raloxifene on serum levels of insulin-like growth factor-I (IGF-I) and insulin-like growth factor binding protein-3 (IGFBP-3) and on the IGF-I/IGFBP-3 ratio. Raloxifene Hydrochloride insulin like growth factor 1 Homo sapiens
2 OBJECTIVE: To assess and compare the effect of conjugated estrogen and of the selective estrogen receptor modulator raloxifene on serum levels of insulin-like growth factor-I (IGF-I) and insulin-like growth factor binding protein-3 (IGFBP-3) and on the IGF-I/IGFBP-3 ratio. Raloxifene Hydrochloride insulin like growth factor 1 Homo sapiens
3 RESULT(S): Both raloxifene and CEE decreased serum IGF-I concentration. Raloxifene Hydrochloride insulin like growth factor 1 Homo sapiens
4 Compared with placebo, the decrease in IGF-I/IGFBP-3 ratio was -32.5% (95% CI: -20.1; -44.8%) for CEE; -16.4% (95% CI: -3.6; -29.2%) for raloxifene at 150 mg/day; and -15.4% (95% CI: -1.0; -29.8%) for raloxifene at 60 mg/day. Raloxifene Hydrochloride insulin like growth factor 1 Homo sapiens
5 Compared with placebo, the decrease in IGF-I/IGFBP-3 ratio was -32.5% (95% CI: -20.1; -44.8%) for CEE; -16.4% (95% CI: -3.6; -29.2%) for raloxifene at 150 mg/day; and -15.4% (95% CI: -1.0; -29.8%) for raloxifene at 60 mg/day. Raloxifene Hydrochloride insulin like growth factor 1 Homo sapiens
6 CONCLUSION(S): Long-term use of both CEE and raloxifene decreases serum IGF-I and the IGF-I/IGFBP-3 ratio, but, unlike CEE, raloxifene produced a significant yet small increase in IGFBP-3. Raloxifene Hydrochloride insulin like growth factor 1 Homo sapiens
7 CONCLUSION(S): Long-term use of both CEE and raloxifene decreases serum IGF-I and the IGF-I/IGFBP-3 ratio, but, unlike CEE, raloxifene produced a significant yet small increase in IGFBP-3. Raloxifene Hydrochloride insulin like growth factor 1 Homo sapiens
