美国Genzyme生物制药公司药品Renvela用于慢性肾病（CKD）患者，以控制他们体内血清磷水平，这为专业医师提供了一种治疗高磷酸盐血症的全新选择。

值得指出的是，欧盟同时批准了该药的片剂和粉剂两种剂型。其中粉剂是该公司另一种磷酸盐粘结剂Renagel的下一代产品，可用于未接受过透析治疗，且体内血清磷水平≤1.78mmol/L的患者。
导致高磷酸盐血症的原因是患者肾脏发生病变，难以将体内的磷滤除并排除体外，而血清磷含量的升高会导致身体组织钙化，从而进一步增加发生心脏病的风险。若 对这种情况不加以治疗，还有可能出现骨痛、骨骼畸形和骨折等，因此，将血清磷含量维持在一个理想的水平对CKD患者来说是一种重要的治疗途径。
目前，Renvela和Renagel是唯独不含钙和任何金属成分的磷酸盐粘结剂。它们通过批准的依据均是多项临床实验的喜人结果——患者用药后体内的磷含量可以维持在正常的范围。
enzyme公司肾病药事业部负责人表示，Renvela能获准进入欧洲市场意味着在CKD治疗领域又前进了一步。该药是第一种在欧洲集中审批程序下获准，可用于治疗从未进行过透析CKD患者的产品，也为医师提供了一种可尽早治疗，控制病情的新药
