Study to Compare Safety and Pharmacokinetics of "CG1801" and "CGL1802" in Healthy Volunteers

Healthy volunteers are administrated single-dose over the period I and II (crossover) of CGL1802(Polmacoxib 2mg Tablet) and CG1801(Polmacoxib 2mg capsule) Every time before and after each medication, pharmacokinetic (PK) parameters and safety of CGL1802 and CG1801 is performed using a blood sample and conducting some tests (vital signs, physical exam, ECG, laboratory test, etc.) respectively.
