Detailed Description:

The purpose of this study is to evaluate and compare the relative bioavailability of Quinine Sulfate 324 mg capsules, manufactured by the Mutual Pharmaceutical Company, to Quinine Sulphate 300 mg tablets, manufactured by the Government Pharmaceutical Organization, Bangkok Metropolis, Thailand, after single oral dose administration under fasting conditions. An additional purpose of this study is to evaluate the effect of food on the Mutual Pharmaceutical Company product.

Twenty-seven healthy, non-smoking, non-obese, male and female volunteers at least 18 years of age will be randomly assigned in crossover fashion to receive each of three dosing regimens in sequence with a 7 day washout period between dosing periods. In each of the three dosing periods, after a fast of at least 10 hours, subjects will receive one dose of one of the three test products (treatment A - quinine sulfate capsules 324 mg, treatment B - quinine sulphate tablets 300 mg, treatment C - quinine sulfate capsules 324 mg administered thirty minutes after the initiation of a standardized, high-fat breakfast). Subjects will fast for 4 hours after dosing. Blood samples will be drawn from all participants before dosing and for 48 hours post-dose at times sufficient to adequately define the pharmacokinetics of quinine sulfate under fed and fasting conditions and quinine sulphate under fasting conditions. Sitting blood pressure and heart rate will be obtained prior to dosing and at 1, 2, 4 and 12 hours post-dose and upon completion of the study. An electrocardiogram will be recorded at check-in and at 2, 4, 6, 12, and 24 hours post-dose. Subjects will be monitored throughout their participation in the study for adverse reactions.

  Eligibility

Ages Eligible for Study:   18 Years and older
Genders Eligible for Study:   Both
Accepts Healthy Volunteers:   Yes
Criteria

Inclusion Criteria:

  • Screening Demographics: All volunteers selected for this study will be healthy men or women at least 18 years of age, inclusive, at the the time of dosing. The weight range will not exceed ± 20% for height and body frame as per Desirable Weights for Adults - 1983 Metropolitan Height and Weight Table
  • Screening procedures: Each volunteer will complete the screening process within 28 days prior to Period I dosing. Consent documents for both the screening evaluation and HIV antibody determination will be reviewed, discussed, and signed by each potential participant before full implementation of screening procedures.
  • Screening will include general observations, physical examination, demographics, medical and medication history, an electrocardiogram, sitting blood pressure and heart rate, respiratory rate and temperature. The physical examination will include an evaluation of the cardiovascular, gastrointestinal, respiratory and central nervous systems.
  • The screening clinical laboratory procedures will include:
  • HEMATOLOGY: hematocrit, hemoglobin, WBC count with differential, RBC count, platelet count
  • CLINICAL CHEMISTRY:serum creatinine, BUN, glucose, AST(GOT), ALT(GPT), albumin, total bilirubin, total protein, and alkaline phosphatase
  • HIV antibody and hepatitis B surface antigen screens
  • URINALYSIS: by dipstick; full microscopic examination if dipstick positive; and
  • URINE DRUG SCREEN: ethyl alcohol, amphetamines, barbiturates, benzodiazepines, cannabinoids, cocaine metabolites, opiates and phencyclidine
  • SERUM PREGNANCY SCREEN (female volunteers only)

If female and:

  • of childbearing potential, is practicing an acceptable method of birth control for the duration of the study as judged by the investigator(s), such as condom with spermicide, diaphragm, intrauterine device (IUD), or abstinence; or
  • is postmenopausal for at least 2 years; or
  • is surgically sterile (bilateral tubal ligation, bilateral oophorectomy, or hysterectomy)

Exclusion Criteria:

  • Volunteers with a recent history of drug or alcohol addiction or abuse
  • Volunteers with the presence of a clinically significant disorder involving the cardiovascular, respiratory, renal, gastrointestinal, immunologic, hematologic, endocrine, or neurologic system(s) or psychiatric disease (as determined by the clinical investigators)
  • Volunteers whose clinical laboratory test values are outside the accepted reference range and when confirmed on re-examination are deemed to be clinically significant
  • Volunteers demonstrating a positive hepatitis B surface antigen screen or a reactive HIV antibody screen
  • Volunteers demonstrating a positive drug screen when screened for this study
  • Female volunteers demonstrating a positive pregnancy screen
  • Female volunteers who are currently breastfeeding
  • Volunteers with a history of allergic response(s) to quinine or related drugs
  • Volunteers with a history of clinically significant allergies including drug allergies
  • Volunteers with a history of clinically significant illness during the 4 weeks prior to Period I dosing (as determined by the clinical investigators)
  • Volunteers who currently use tobacco products
  • Volunteers who have taken any drug known to induce or inhibit hepatic drug metabolism in the 28 days prior to Period I dosing
  • Volunteers who report donating greater than 150mL of blood within 28 days prior to Period I dosing. All subjects will be advised not to donate blood for four weeks after completing the study
  • Volunteers who have donated plasma (e.g. plasmapheresis) within 14 days prior to Period I dosing. All subjects will be advised not to donate plasma for four weeks after completing the study
  • Volunteers who report receiving any investigational drug within 28 days prior to Period I dosing
  • Volunteers who report taking any systemic prescription medication in the 14 days prior to Period I dosing
  • Volunteers with QTc >480 msec on the screening electrocardiogram (ECG) or with clinically significant findings
  • Volunteers who have a glucose-6-phosphate dehydrogenese deficiency (G6PD)
