Single Dose Pravastatin Pharmacokinetics in Pediatric Peritoneal Dialysis Patients

A Single-dose Pilot Study to Evaluate the Pharmacokinetics of Pravastatin Given as an Oral Dose in Pediatric and Adolescent Subjects 12 Months to 16 Years of Age Receiving Continuous Cycling Peritoneal Dialysis

Many children with end stage renal disease develop hyperlipidemia. HMG-CoA (3-hydroxy-3-methylglutaryl-coenzyme A) reductase inhibitors, such as pravastatin, are typical treatments for hyperlipidemia. However, we do not know how pravastatin is metabolized in patients on dialysis. This study is designed to provide preliminary pharmacokinetic data for pravastatin in pediatric patients on peritoneal dialysis.

This is a single-dose pilot study to evaluate the pharmacokinetic profile of pravastatin in 7 pediatric and adolescent subjects ranging from 12 months to 16 years of age who are on dialysis. The study group will be comprised of healthy children receiving continuous cycling peritoneal dialysis (CCPD). Pravastatin dosing will be 10 mg in all subjects. Blood, urine, and dialysate samples will be obtained over a 24-hour period post-dose for measurement of pravastatin concentrations. Safety evaluations will include adverse events (AEs), physical examination, vital signs, and clinical laboratory evaluations.

Inclusion Criteria:

1. Patients from 12 months to 18 years of age.

2. Patients with end stage renal disease who receive continuous cycling peritoneal dialysis.

3. signed informed consent

4. Physical exam demonstrates no abnormalities that would make this study medically hazardous to the subject.

6. Known hypersensitivity to pravastatin
7. Unwilling to have blood samples drawn
8. Has taken a HMG-CoA reductase inhibitor in the last week -
