描述 | Ibandronate Sodium is a highly potent nitrogen-containing bisphosphonate used for the treatment of osteoporosis. Low-dose ibandronate (1.25-2 microM) significantly reduced endothelial cell growth, while 2 microM ibandronate also significantly reduced capillary-like tube formation and increased apoptosis of endothelial cells compared to untreated cells. There was no significant difference in activity with doses above 2 microM[3]. Ibandronate (0.5 to 5 mg/day orally or 0.5 to 2 mg every 3 months intravenously) dose-dependently increased bone mineral density, with parallel reductions in the biochemical markers of bone turnover. In preliminary studies in patients with Paget's disease a single intravenous ibandronate dose (2mg) decreased serum alkaline phosphatase levels and urinary markers of bone turnover[4]. Ibandronate effectively inhibits growth of prostate cancer cell lines via inhibition of the farnesyl-IPP-synthase and exhibits synergistic effects with docetaxel[5]. Ibandronate (< 125 mg/kg s.c.) results in a dose dependent increase in bone mineral density (BMD), trabecular bone volume and trabecular number, load to failure (Fmax), and yield load in long bones and vertebrae in ovariectomized rats, and increased trabecular separation in ovariectomized rats is fully prevented by all doses[6]. |
