Exclusion criteria
Exclusion criteria: 1. History of any illness or condition that, in the opinion of the investigator, might confound the results of the study or pose an additional risk in administering study drug to the subject. 2. Cholecystectomy and/or surgery of the gastrointestinal tract that could interfere with pharmacokinetics of the trial medication (except appendectomy and simple hernia repair). 3. Regular treatment with prescription medications. Subjects should have ended any prescription medications at least 14 days before the first dosing of the study drug. Potential subjects should only stop any prescribed medication at the direction of a physician. 4. Regular treatment with nonprescription medications.

Potential subjects should consult a physician before stopping any regular treatment with nonprescription medication. 5.

History of drug or alcohol abuse or addiction within 2 years before the start of study drug dosing, or a positive test for alcohol or drugs of abuse, such as cotinine, amphetamines, barbiturates, benzodiazepines, cannabinoids, cocaine, or opioids at screening. 7. Regular consumption of more than 2 units of alcoholic beverages per day or more than 14 units per week (1 unit of alcohol equals 1 pint [473 mL] of beer or lager, 1 glass [125 mL] of wine, 25 mL shot of 40% spirit) before screening. Subjects may not consume any alcohol from 72 hours before the first dosing of study drug through the completion of the study (last visit). 8. Consumption of an average of more than 5 servings (8 ounces per serving) per day of coffee, cola, or other caffeinated beverage before screening. Subjects may not consume any caffeinated beverages from 48 hours prior to dosing until the collection of the last PK sample. 9. Participation in a clinical study involving administration of either an investigational or a marketed drug within 3 months before screening. 10. Blood donation or a significant loss of blood within 60 days of the start of study drug dosing or donation of more than 1 unit of plasma within 7 days before screening. 11. Positive result at screening for any of the following infectious disease tests: hepatitis B surface antigen (HBsAg), hepatitis C virus antibody (HCV Ab), or human immunodeficiency virus antigen, antibody (HIV Ag, Ab). 12. Illness within 5 days before the start of study drug dosing (“illness” is defined as an acute [serious or non-serious] condition [e.g., the flu or the common cold]). 13. Subjects with rare hereditary problems of galactose intolerance, the Lapp lactose deficiency or glucose-galactose malabsorption. 14.
