[New Developments in CKD-MBD. New aspects in phosphate binders].

In patients with end-stage renal disease (ESRD) , hyperphosphatemia contributes to secondary hyperparathyroidism and can lead to skeletal complications including fracture, and vascular calcification. Currently employed phosphate binders include calcium carbonate, sevelamer hydrochloride, and lanthanum carbonate. While these agents are effective at binding orally ingested phosphates, they vary in safety, potency, and off-target effects, some of which may be salutary (e.g., low-density lipoprotein and uric acid lowering with sevelamer) and others adverse (low turnover bone disease and progressive vascular calcification with calcium) . There remains a large unmet need for safe and effective phosphate binders with favorable off-target effects.
