CELECOXIB Plasma and Cerebral Spinal Fluid Pharmacokinetics in Children
Sponsor: Children's Hospital of Eastern Ontario
Summary
Celecoxib is effective for reducing postoperative pain in adults. Children use celecoxib more rapidly than adults and require higher doses. Celecoxib is partially metabolized in the liver by a certain enzyme. A person's genetic variation of this enzyme can influence how well their body uses Celecoxib. Furthermore, Celecoxib down-regulates P-glycoprotein (P-gp), a drug efflux transporter located at the blood brain barrier responsible for central nervous system (CNS) extrusion of ondansetron and possibly fentanyl; therefore celecoxib may augment the CNS effects of these drugs. Understanding the blood and cerebrospinal fluid (CSF) profile of celecoxib in children and the influence of genetics on metabolism would help to develop appropriate celecoxib dosing in children for various treatment options.

Interventions
Celecoxib
In Phase I twenty (20) children will receive either celecoxib 14 or 7 mg/kg 120-180 minutes prior to lumbar puncture (LP). In Phase II forty-five (45) children will receive celecoxib 14 mg/kg, 7 mg/kg or placebo in one of 5 time intervals, 1-24 hours prior to LP.
Placebo
In Phase II forty-five (45) children will receive celecoxib 14 mg/kg, 7 mg/kg or placebo in one of 5 time intervals, 1-24 hours prior to LP.
