A Clinical Study to Compare the Pharmacokinetic Characteristics of CKD-395 0.25/500mg in Healthy Male Volunteers

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.

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.)
