In Brazil, sertraline is currently available as film coated tablets for oral administration containing sertraline hydrochloride equivalent to 50 mg or 100 mg sertraline.

The sponsor has developed an oral solution formulation containing 20 mg/mL of sertraline, which must be diluted with 120 mL of water, ginger ale, lime/lemon soda or orange juice to be palatable before use. The purpose of this study is to evaluate the relative bioavailability of Zoloft oral solution compared to Zoloft tablets in healthy participants under fasted conditions.

• Any condition possibly affecting drug absorption (eg, gastrectomy, colon resection, etc.).
• Research subjects with a history of, or current evidence for, severe gastrointestinal narrowing (pathologic or iatrogenic).
• History of or current positive results for any of the following serological tests: hepatitis B surface antigen (HBsAg), hepatitis B core antibody (HBcAb), anti hepatitis C core antibody (HCV Ab), or human immunodeficiency virus (HIV) 1 and 2.

• History of regular alcohol consumption exceeding 14 drinks/week for female research subjects or 21 drinks/week for male research subjects [1 drink = 5 ounces (150 mL) of wine or 12 ounces (360 mL) of beer or 1.5 ounces (45 mL) of hard liquor] within 6 months before screening.
• Use of tobacco or nicotine containing products in excess of the equivalent of 5 cigarettes per day. For chewing tobacco, one chew is equivalent to approximately 2 3 cigarettes, so research subjects would be limited to 2 or less chews per day.
• Treatment with an investigational drug within 6 months or 5 half lives preceding the first dose of investigational product (whichever is longer).
• Pregnant female research subjects, breastfeeding female research subjects, fertile male research subjects and female research subjects of childbearing potential who are unwilling or unable to use a highly effective method of contraception as outlined in this protocol from at least 14 days prior to the first dose of investigational product until at least 28 days after the last dose of investigational product.
• A positive beta human chorionic gonadotropin test for women of childbearing potential.
• Use of prescription or nonprescription drugs and dietary supplements within 14 days or 5 half lives (whichever is longer) prior to the first dose of investigational product.
• Herbal supplements, hormonal methods of contraception (including oral and transdermal contraceptives, injectable progesterone, progestin subdermal implants, progesterone releasing intrauterine devices [IUDs], vaginal ring, and postcoital contraceptive methods), and hormone replacement therapy must have been discontinued at least 28 days prior to the first dose of investigational product.

• Unwilling or unable to comply with the criteria in the Lifestyle Requirements section of this protocol.
• Other acute or chronic medical or psychiatric condition including recent (within the past year) or active suicidal ideation or behavior or laboratory abnormality that may increase the risk associated with study participation or investigational product administration or may interfere with the interpretation of study results and, in the judgment of the investigator, would make the research subject inappropriate for entry into this study.
• Research subjects who are investigator site staff members directly involved in the conduct of the study and their family members, site staff members otherwise supervised by the investigator, or research subjects who are the sponsor's employees, including their family members, directly involved in the conduct of the study.
