Estimated Enrollment: 28
Study Start Date: February 2009
Primary Completion Date: May 2010 (Final data collection date for primary outcome measure)
Arms Assigned Interventions
Experimental: combination
long acting Metformin/Glimepiride
Drug: metformin/glimepiride combination
long acting metformin/glimepiride 1g/2mg
Active Comparator: metformin
metformin hydrocloride
Drug: metformin
long acting metformin 1g once a day with fasting glucose 130-199mg/dL or long actin metformin 1g twice a day (before dinner and before breakfast) with fasting glucose 200-270mg/dL
Active Comparator: glimepiride
Drug: glimepiride

Detailed Description:
A randomized double-blind clinical trial, to determine the effect of combined therapy of oral prolonged-release metformin/glimepiride in a single dosage form on fasting glucose and HbA1c. Patients will be included in this study are patients with diabetes mellitus and secondary failure to monotherapy. Will also assess the effect of combined therapy on the oral lipid profile (total cholesterol, LDL, HDL, VLDL, Triglycerides) and on the sensitivity and insulin secretion. We evaluate the clinical measurements, laboratory and safety during 3 months, through the allocation of subjects to three study groups (metformin, glimepiride and metformin extended release / glimepiride)
