Exclusion Criteria: * Those who have taken drugs that induce and inhibit metabolizing enzymes such as barbiturate within 30 days before the first administration date or have taken drugs concerned about affecting this clinical trial within 10 days before the first administration date. (However, participation is possible considering pharmacokinetics and pharmacodynamics such as Interaction of investigational products, half-life of concomitant drugs, etc.) * Those who have a medical history of gastrointestinal resection or gastrointestinal diseases that may affect the absorption of drugs. (Except for simple appendectomy, hernia surgery) * Those who have participated in other clinical trials(including bioequivalence tests) and administered their investigational products within 6 months before the first administration date. (However, the termination for participation in other clinical trials are based on the last administration date of their investigational products) * Those who can't discontinue a diet (ex. raw grapefruit, grapefruit juice or food containing grapefruit, etc.) that may affect the absorption, distribution, metabolism, and excretion of the drug within 48 hours before the first administration date * In the case of a female subject, those suspected pregnancy or pregnant woman or lactating woman.
