Trial Title: Effect of Weight and/or Obesity on Sulfamethoxazole and Trimethoprim Concentrations

Study Design Characteristics:
- Allocation: None
- Intervention Model: SINGLE_GROUP
- Observational Model: None
- Primary Purpose: TREATMENT
- Time Perspective: None
- Masking: NONE
- Phase: PHASE4
- Number of Arms: 1.0

Eligibility Criteria:
Inclusion Criteria:~* Male and female subjects, age \>18 years, of all racial and ethnic origins.~* We are recruiting 12 normal or underweight (BMI \<25kg/m2), 12 overweight or obese (BMI 25-40 kg/m2), and 12 extremely obese (BMI \> 40 kg/m2) for this study. This index is calculated using the volunteer's height and weight (Formula: weight (lb) / \[height (in)\]2 x 703). Half of each group will be male; the other half will be female.~Exclusion Criteria:~* Pregnant or nursing or unwilling to use a reliable contraception method during the study. The effects of sulfamethoxazole and trimethoprim on pregnancy are unknown. In addition, the metabolic changes that accompany pregnancy may alter the concentration-time profile of sulfamethoxazole and trimethoprim, so that the pregnancy and post-partum state would be a confounding variable.~* Abnormal liver function tests: transaminases\>10 times upper limit of normal, Alkaline phosphatase\>5 times upper limit of normal, total bilirubin\>5 times upper limit of normal.~* History of allergies to sulfones, sulfonamides or trimethoprim.~* Sulfones, sulfonamides or trimethoprim are contraindicated for any reason.~* Volunteers unwilling to comply with study procedures.~* Current suspected or documented ear infection, urinary tract infection, bronchitis, traveler's diarrhea, Pneumocystis carinii pneumonia, or any other bacterial infection.~* Volunteers with colon resection, gastric bypass, lap band, or any other conditions inhibiting gastric absorption of drug.~* Current or previous participation within 28 days of enrollment in another research study that involves the use of medication, contrast, or any other compound that may alter blood count and/or blood chemistry (liver function, kidney function or electrolyte balance), unless waved by PI.~* Donation of 450mL (one unit) of blood or more within 8 weeks (56 days) prior to study enrollment, unless waved by PI.~* Current use of medications contraindication with sulfamethoxazole/trimethoprim use: Bepridil, Cisapride, Dofetilide, Levomethadyl, Mesoridazine, Pimozide, Terfenadine, and Thioridazine. Other medications will be screened by study investigators to ensure the safety of research participants and maintain the quality of the study.
