Objective To observe the safety and efficacy of metformin in the long-term treatment of elderly T2DM patients. Methods Of the elderly T2DM cases, 18 were taking metforrnin and 18 were not taking metformin during the 9-year treatment. The blood glucose, HbA1 c, liver and renal functions of all of the cases were regularly determined for comparison. Results At the end of the 9th year, the success rate of 7. 0 HbA1 c was 77. 78% and 50% respectively in treatment and control groups, with a statistical difference （P〈0. 05）. The differences of liver and kidney function as well as the body weight between the two groups were not significant, and the GFR of both groups was within the normal range of fluctuation. Conclusion Elderly T2DM patients taking metformin for long-term treatment can achieve a good result in controlling blood glucose without safety hazards.
