- • 3. Normal laboratory values, including vital signs and physical examination, for all parameters in clinical laboratory tests at screening.
- • Any abnormalities from the normal or reference range will be carefully considered clinically relevant by the physician as individual cases, documented in study files prior to enrolling the subject in this study
- • 4. Male subjects who are not wishing to be a father of a child during the study or who are willing or able to use effective contraceptive e.g. condom or abstinence after check-in until 30 days after investigational product administration.

- • 2. History of allergic reaction or hypersensitivity to cholestyramine
- • 3. History or evidence of clinically significant renal, hepatic, gastrointestinal, hematological (e.g. anemia), endocrine (e.g. hyper-/hypothyroid, diabetes), pulmonary or respiratory (e.g. asthma, COPD), cardiovascular (e.g. hyper-/hypotension), psychiatric, neurologic (e.g. convulsant), allergic disease (including drug allergies, but excluding untreated, asymptomatic, seasonal allergies at time of dosing) or any significant ongoing chronic medical illness

- • 8. History or evidence of moderate to severe renal insuffici
- • 9. History or evidence of severe hypoproteinaemia or nephrotic syndrome
- • 10. Investigation with blood sample shows albumin level less than 3.5 g/dl or more than 5.2 g/dl at screening

- • 14. Have sitting systolic blood pressure of less than 90 mmHg or more than 139 mmHg and diastolic blood pressure of less than 60 mmHg or more than 89 mmHg on screening day and check-in day. If abnormal blood pressure detects, the measurement should be repeated two more times after take a rest for at least 5 mins each. The last measurement value should be used to determine the subject's eligibility

If QTc exceeds 450 msec, or QRS exceeds 120 msec, the ECG will be repeated two more times and the average of the three QTc or QRS values will be used to determine the subject's eligibility.
