沙格列汀（英语：Saxagliptin），商品名为安立泽，是一种二肽基肽酶-4抑制剂类口服抗糖尿病药。沙格列汀早期由百时美施贵宝单独研发，2007年，阿斯利康制药也加入了研发并共同负责销售。

2014年2月，基于一篇在新英格兰医学杂志发表的文章，美国食品药品监督管理局（FDA）宣布他们正在调查沙格列汀可能会导致的心脏病发病风险。 文章总结指出，DPP-4抑制剂不会增加或减少缺血的发生几率，虽然因心力衰竭而入院治疗的几率有所增加。即使沙格列汀可以控制血糖，但是需要为伴有心血管疾病的糖尿病人增加其他治疗手段，防止心血管疾病发病风险的提高。

Saxagliptin (rINN), previously identified as BMS-477118, is an oral hypoglycemic (anti-diabetic drug) of the dipeptidyl peptidase-4 (DPP-4) inhibitor class of drugs. Early development was solely by Bristol-Myers Squibb; in 2007 AstraZeneca joined with Bristol-Myers Squibb to co-develop the final compound and collaborate on the marketing of the drug. In June 2008, it was announced that Onglyza would be the trade name under which saxagliptin will be marketed.
