Abstract
OBJECTIVE: To evaluate the safety of metformin in the treatment of elderly type 2 diabetes mellitus (T2DM). METHODS: Two hundred and forty-three cases of elderly T2DM hospitalized from Jan. 1996 to Dec. 2006 were reviewed; the changes of fasting blood glucose(FBG), postprandial blood glucose (PBG), glycosylated hemoglobin (HbA1c), liver and renal function and blood lactic acid were evaluate before and after treatment. RESULTS: The mean time of treatment with metformin was (6.6 +/- 3.9) years (3 months - 21 years) in these 243 cases. The levels of FBG, PBG and HbA1c significantly reduced after treatment with metformin only in 43 cases (17.7%), metformin combined with other oral hypoglycemic drugs in 124 cases (51.0%) and metformin combined with insulin in 76 cases (31.3%). There was only 18.1% of the cases with normal range (> 80 ml/min) of creatinine clearance rate (Ccr), and 25.8% of the cases with Ccr
