阿格列汀（英语：Alogliptin）， 商品名为尼欣那，是一种二肽基肽酶-4（DPP-4）抑制剂类口服抗糖尿病药 ，由日本武田药品工业株式会社研发于2005年。与其他治疗2型糖尿病的药物一样，阿格列汀不会增加心脏病与中风的风险。与其他列汀类药物相似，阿格列汀几乎不会导致体重增加，并且导致低血糖的风险相对较低，有着适度的降糖活性。阿格列汀和其他列汀类药物一样常与二甲双胍合用，用于无法单独用二甲双胍控制血糖的病人。

Alogliptin (trade name Nesina in the US and Vipidia in Europe) is an orally administered anti-diabetic drug in the DPP-4 inhibitor class, developed by Syrrx, a company which was acquired by Takeda Pharmaceutical Company in 2005. Like other medications for the treatment of Type 2 diabetes, alogliptin does not decrease the risk of heart attack and stroke. Like other members of the gliptin class, it causes little or no weight gain, exhibits relatively little risk of causing hypoglycemia, and exhibits relatively modest glucose-lowering activity. Alogliptin and other gliptins are commonly used in combination with metformin in patients whose diabetes cannot adequately be controlled with metformin alone. In April 2016, the U.S. FDA added a warning about increased risk of heart failure.
