Population Pharmacokinetics and Pharmacogenomics of Oral Oxycodone in Pediatric Surgical Patients

Running, not enrolling · Phase 4

Conditions studied: Pediatric Surgical Patient

In brief

Oxycodone is an oral opioid analgesic that is most commonly prescribed for the management of pain in post-operative patients at Boston Children's Hospital. Oxycodone has been widely used in adults and children to relieve post-operative pain. However, its pharmacokinetics (what it does in the body) and pharmacodynamics (how it works) have not been well established in children. Some children, because of their specific genetic make-up, may metabolize the drug more quickly and therefore may be at risk for more side effects in the commonly prescribed dose. We would like to find out more about how this drug is absorbed, metabolized and excreted in children. In order to study these aspects, we would like to give oxycodone to surgical patients at Boston Children's Hospital then measure its metabolic activity and also perform a genetic analysis. The genetic testing is specifically to analyze the following genotypes only: cytochrome P450 2D6 (CYP2D6) and cytochrome P450 3A4 (CYP3A4), which represent the differences in cytochrome P450 metabolism of oxycodone.

Who can join

Age: any, up to 6. Sex: any. Healthy volunteers: not accepted.

You may qualify if…

• A total of 68 generally healthy, opioid-naive children, aged 0-6 years, scheduled as in-patient surgery for ventriculoperitoneal shunt placement/revision or Craniotomy (Neurosurgery service), Cleft lip/palate repair (plastic surgery service) and hypospadias repair or ureteral urethral reimplantation (genitourinary surgery service) will be enrolled in the study.

You may not qualify if…

• Children will be excluded if they are currently taking any medications which are CYP3A4 or CYP2D6 inhibitors/inducers or have a history of allergy or hypersensitivity to oxycodone, have any condition that might interfere with GI absorption, distribution, hepatic metabolism or renal excretion of r oxycodone, or a diagnosis of sleep apnea or impaired respiratory reserve.
