This study is a randomized, open-label, single dose, crossover study to evaluate the pharmacokinetics and safety of CKD-383 in healthy volunteers.

To 30 healthy subjects, following treatments, are administered dosing in each period and wash-out period is 7 days. Pharmacokinetic blood samples are collected up to 48hrs. The pharmacokinetic characteristics and safety are assessed.

3. Individuals who do not have clinically meaningful congenital or chronic diseases and who do not have medical examination results (such as electroencephalogram, electrocardiogram, chest and gastroscopy or gastrointestinal radiography, if necessary) during screening visits
4. Individuals determined by investigators to be suitable for testing as a result of diagnostic tests and electrocardiogram tests, such as hematology tests, blood chemistry tests, serum tests, urine tests, etc
