1 Inhibition of dipeptidyl peptidase IV activity by oral metformin in Type 2 diabetes. Metformin dipeptidyl peptidase 4 Homo sapiens
2 We investigated the acute effects of metformin on DPP IV activity in Type 2 diabetes to elucidate inhibition of DPP IV as a possible mechanism of action. Metformin dipeptidyl peptidase 4 Homo sapiens
3 RESULTS: Following metformin, DPP IV activity was suppressed compared with placebo (AUC0-6 h 3230+/-373 vs. 5764+/-504 nmol ml/l, respectively, P=0.001). Metformin dipeptidyl peptidase 4 Homo sapiens
4 Metformin also concentration-dependently inhibited endogenous DPP IV activity in vitro in plasma from Type 2 diabetic subjects. Metformin dipeptidyl peptidase 4 Homo sapiens
5 CONCLUSION: Oral metformin effectively inhibits DPP IV activity in Type 2 diabetic patients, suggesting that the drug may have potential for future combination therapy with incretin hormones. Metformin dipeptidyl peptidase 4 Homo sapiens
