KATP channels x HMG-CoA reductase x SUR

The aim of this 20 week study is to show that glimepiride/atorvastatin fixed dose combination tablet is safe and as effective as atorvastatin + glimepiride combination taken as separate tablets, in improving glycaemic control (glycated haemoglobin, HbA1c) and cholesterol levels (Low-density lipoprotein, LDL) in diabetic subjects, who are inadequately controlled on a stable dose of metformin. Eight dose combinations will be included.
