This study is a randomized, open-label, single dose, 2-way crossover study to compare the pharmacokinetic characteristics of CKD-395 0.25/500 mg in healthy male volunteers.

To healthy male subjects of twenty six(26), following treatments are administered dosing in each period fed condition(high fat meals) and wash-out period is a minimum of 7 days.

Treatment A(Reference Drug): DuvieTM Tab. 0.5mg 1T + Glucophage XR Tab. 500mg 2T Treatment B(Test Drug): CKD-395 0.25/750mg Tab. 2T

Pharmacokinetic blood samples are collected up to 48hrs. Safety and pharmacokinetic are assessed.

3. Who had following results after examination

   a. ALT or AST > twice higher than normal value

4. Who constantly intake 210 g/week of alcohol within 6 months of the screening. (a cup of beer (5%) (250mL) = 10 g, a shot of soju (20%) (50mL) = 8 g, a glass of wine (12%) (125 mL) = 12 g)

5. Who participated other clinical test or took testing bioequivalence drugs in 3 months before the first clinical drug trial

6. Whose blood pressure > 140 mmHg (systolic blood pressure) or > 90 mmHg (diastolic pressure)

7. Who had a medical history of alcohol and drug abuses.

8. Who had taken a drug that has a control of metabolic rate (activation or inhibition) in 30 days before the first taking of clinical testing drug

9. Who smokes more than 20 cigarettes per day

10. Who took prescribed drugs or over-the-counter drugs in 10 days before taking of very first clinical testing drug

11. Who participated in whole blood donation in 2 months before the first taking of clinical testing drugs or platelet donations in 1 month before the first taking to clinical testing drugs.

12. Who has a potent to increase a danger by participating in the clinical trials or who can interrupt interpreting test results by having serious or chronic medical and mental status or having issues in results of the screening examination.

13. Who has a history of an extreme sensitivity of drugs that contain Rosiglitazone or drugs that have similar effect as Rosiglitazone (Pioglitazone), or drugs that contain the ingredients of Metformin or biguanidine drugs

14. Who has a serious heart failure or a congestive heart failure that must be drug-treated

20. A patient who has kidney disease or renal insufficient that are caused by cardiovascular collapse (shock) and acute myocardial infarction (a male with higher serum creatinine of 1.5mg / dL, or less creatinine clearance of 80 mL / min)

21. A patient who is being tested to inject radiological iodine contrast agent into blood vessels (ex: intravenous urography, intravenous cholangiography, angiography, using contrast medium computer tomography, etc.)
