Primary purpose: BASIC_SCIENCE

Brief summary: This study is to assess the bioequivalence between fluconazole 50mg capsules from two different manufacturers. This is a open-label, randomized, single dose, 2-treatment, 2-period crossover study in healthy Korean male and female subjects aged 19-55, to assess the bioequivalence after taking study drugs.

Detailed description: Twenty-eight (28) healthy subjects will be enrolled into the study. Screening evaluation will occur within 28 days prior to the first dose of study medication.

Subjects will be randomized to the following treatments:

* Treatment A: Fluconazole capsule, 1 x 50 mg, Diflucan, West Ryde (REFERENCE)
* Treatment B: Fluconazole capsule, 1 x 50 mg, Diflucan, Amboise (TEST)

Eligibility criteria: Inclusion Criteria

* Healthy male and subjects who are between the ages of 19 and 55 years.
* Female subjects who are found not to be pregnant in physical examinations
* BMI of 17.5 to 30.5 kg/m2; and a total body weight \>50 kg (110 lb).
* Evidence of a personally signed and dated informed consent document indicating that the subject has been informed of all pertinent aspects of the study.
* Subjects who are willing and able to comply with all study procedures.

Exclusion Criteria

* Evidence or history of clinically significant disease
* Any condition possibly affecting drug absorption (eg, gastrectomy).
* A positive urine drug test.
* History of regular alcohol consumption exceeding standard for the study
* Treatment with an investigational drug within 3 months or 5 half-lives preceding the first dose of investigational product (whichever is longer).
* Screening seated BP 140 mm Hg (systolic) or 90 mm Hg (diastolic) and over
* Screening supine 12-lead ECG demonstrating a corrected QT (QTc) interval over 450 msec or a QRS interval over 120 msec.
* Subjects with ANY of the following abnormalities in clinical laboratory tests at screening, when assessed by the study-specific laboratory and confirmed by a single repeat test:

  • Aspartate aminotransferase (AST) or alanine aminotransferase (ALT) level over 2 upper limit of normal (ULN); Total bilirubin level 2.0 mg/mL and over; subjects with a history of Gilbert's syndrome may have direct bilirubin measured and would be eligible for this study provided the direct bilirubin level is same or under ULN.
* Pregnant female subjects, breastfeeding female subjects, male subjects, who are fertile enough and female subjects of childbearing potential for at least 28 days after the last dose of investigational product.
* Use of prescription or nonprescription drugs and dietary supplements within 10 days or 5 half-lives (whichever is longer) prior to the first dose of investigational product.
* Use of any drugs known to significantly induce (e.g., barbiturates) or inhibit drug- metabolizing enzymes or excessive alcohol consumption within one month prior to the time of screening.
* Blood donation (excluding plasma donations) of approximately 1 pint (500 mL) or more within 60 days prior to dosing.
* History of sensitivity to heparin or heparin-induced thrombocytopenia.
* History of hepatitis B surface antigen (HBsAg), hepatitis C antibody (anti-HCV), human immunodeficiency virus (HIV) antigen or antibody, and/or syphilis (RPR, Rapid Plasma Reagin test).
* Unwilling or unable to comply with the criteria in the Lifestyle Requirements section of this protocol.
* 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 subjects who are Pfizer employees, including their family members, directly involved in the conduct of the study.
* Other acute or chronic medical or psychiatric condition
* Subjects with known sensitivity to the drug or any of the insert ingredients or to related azole compounds.
* Subjects with hereditary problems of galactose intolerance, Lapp lactase deficiency or glucose-galactose malabsorption.
