Clinical Trial Summary

This study will find how weight affects the dosing of a drug called sulfamethoxazole and trimethoprim. Currently, the amount of sulfamethoxazole and trimethoprim a patient receives is the same regardless of the patient's weight. The entire cohort was analyzed for the study outcomes. BMI groups were for recruitment purposes only and were not used for ordinal data analysis.

All sulfamethoxazole and trimethoprim (Trade name is Bactrim or Septra) medication that you will receive in this study will be referred to as study medication within this informed consent form. This drug is a combination of two antibiotics, sulfamethoxazole and trimethoprim, which belongs to a class of medication known as "sulfones" and is approved by the US Food and Drug Administration (FDA) for the treatment of a wide variety of bacterial infections such as ear infections, urinary tract infections, bronchitis, traveler's diarrhea, and Pneumocystis carinii pneumonia. Sulfamethoxazole and trimethoprim is given orally.


Clinical Trial Description

This study is designed to measure drug concentrations in the blood of volunteers administered a single oral dose of sulfamethoxazole and trimethoprim. The volunteers to be enrolled will not have ear infections, urinary tract infections, bronchitis, traveler's diarrhea, Pneumocystis carinii pneumonia, or any other bacterial infection. This is a single center study. A total of 36 adult volunteers will be consented for the study at the Clinical and Translational Research Center (CTRC). Volunteers will be recruited using IRB approved fliers. Volunteers will be admitted to the CTRC for an overnight stay. Half will be female and half male. Twelve volunteers will have a body mass index (BMI) less than 25 kg/m2, twelve will have a BMI 25-40 kg/m2, and twelve will have a BMI greater than 40 kg/m2. Volunteers will have height and weight measured after they have consented to participate. All volunteers will receive a single oral dose of sulfamethoxazole and trimethoprim of 1600 mg/320 mg. The volunteers will have blood drawn via an intravenous catheter just prior to the dose, and then at 1, 2, 4, 8, 12, and 24h after the drug dose. The intravenous catheter is then removed after the 24h blood draw, and the volunteer is discharged from the study. ;
