Results The highest drug use frequency was biguanide. There was 50.9% in the oral antidiabetic drug combination. Leading the first 3 places on the list of drug combination were sulfonylureas in combination with biguanide, sulfonylureas in combination with α-Glycosidace inhibitor, biguanide in combination with α-Glycosidace inhibitor, while there was 16.1% in 3 kinds combination. When oral antidiabetic drugs were combined with other drugs, combination with antihypertensives drugs led the fist, while with antihypertensives drugs led the second.

结果 二甲双胍使用频率最高，口服降糖药联合用药的比例高达50.9%，居前3位的依次是磺脲类＋双胍类、磺脲类＋α-葡萄糖苷酶抑制剂和双胍类＋α-葡萄糖苷酶抑制剂，而3种以上口服降糖药联合用药的比例也达16.1%；口服降糖药与其他药物联合使用情况看，配合使用抗高血压药的频率最高，其次是降脂药。
