Exclusion Criteria

1) A subject who has or has a history of clinically significant hepatobiliary system, kidney, nervous system, respiratory system, blood and tumor, endocrine system, urinary system, mental disease, musculoskeletal system, immune system, otolaryngology, cardiovascular system
2) A subject who has a past history of gastrointestinal diseases (e.g., dysphagia, esophageal disease, gastritis, duodenitis, ulcer, Crohn's disease, acute or chronic pancreatitis), and gastrointestinal operation (excluding simple appendicitis surgery or hernia surgery) that can affect the absorption of clinical medicine
3) Patients with esophageal disorders that delay esophageal transit, such as esophageal stenosis or achalasia
4) Patients who are unable to sit up or stand upright for more than 30 minutes or who are in long-term immobilization (recovery period after surgery, organ stabilizers, etc)
5) A subject with hypersensitivity or has a clinically significant history of hypersensitivity to drugs and other drugs (aspirin, antibiotics, etc) including vitamin D components
