Exclusion Criteria: * Alanine aminotransferase (ALT), aspartate aminotransferase (AST), or alkaline phosphatase (ALP) above 1.1x upper limit of normal (ULN) * Bilirubin \>ULN (isolated bilirubin \<1.5xULN is acceptable if bilirubin is fractionated and direct bilirubin \<35%) * Participant has clinically significant current or past history of cardiovascular or cerebrovascular disease, such as valvular heart disease, and/or pulmonary hypertension.

Note: Patent foramen ovale or a bicuspid aortic valve is not considered exclusionary * Clinically significant abnormal blood pressure (as determined by the investigator) * Participant has a current or past history of glaucoma * Participant has used hepatic enzyme-inducing drugs (eg, glucocorticoids, phenobarbital, isoniazid, phenytoin, rifampicin) within 30 days before the first administration of the cocktail of 3 probe drugs (metformin, midazolam, bupropion) and through the day of discharge from the site * Participant has used other prescription drugs, including vaccinations, over-the-counter medications, herbal/traditional medicines, or dietary supplements within 14 days before the first administration of the cocktail of probe drugs (excluding medicines for external use), with the exception of acetaminophen (up to 2 g/day) * Consent to genotyping is required for participation in the study. Poor metabolizers of CYP (cytochrome P450) 3A4 or CYP2B6 based on genotyping and as categorized by the testing laboratory will be excluded from the study * Positive test for alcohol and/or prohibited concomitant drugs (including cotinine) at Screening Visit and on Day -1 * Participant has donated blood or plasma or has experienced blood loss ≥500 mL within 90 days, ≥200 mL within 30 days, or has donated any blood or plasma within 14 days before first administration of study treatments * Any consumption of food products with a known Drug-drug interaction (DDI) impact (eg, grapefruit, grapefruit juice, Seville oranges, or products containing them) for at least 1 week before Day 1 and through day of discharge from the site * Consumption of more than 600 mg of caffeine/day (1 cup of coffee contains approximately 100 mg of caffeine, 1 cup of tea approximately 30 mg, and 1 glass of cola approximately 20 mg) within 30 days before Day 1 and through day of discharge from the site * Participant is a current smoker or has used nicotine-containing products (eg, tobacco, patches, gum, vapes, or e-cigarettes) within 35 days before Day 1 and through day of discharge from the site
