Summary

The overall purpose of this research study is to investigate the safety of pharmacological therapies that may potentially improve pediatric outcomes after traumatic brain injury. Traumatic brain injuries are the leading cause of death and disability among children and young adults.

Hypothesis: Combinational therapy with a membrane transporter and antioxidant are safe after TBI and can overcome barriers to the brain and synergistically improve bioavailability and efficacy the antioxidant content of the body and CNS after TBI.

Conditions

  • Pediatric Traumatic Brain Injury

Interventions

DRUG

Probenecid and N-acetyl cysteine

After obtaining written parental consent, patients will be randomized by the use of a blind envelope system to one of the following: to receive probenecid (initial: 25 mg/kg/dose; maintenance: 10mg/kg/dose 4 x per day for 11 doses) and NAC (initial: 140mg/kg/dose; maintenance: 70mg/kg/dose 6 x per day for 17 doses) or the placebo via nasogastric (NG) or orogastric (OG) tube for 3 days or to receive placebos.

DRUG

Placebo

After obtaining written parental consent, patients will be randomized by the use of a blind envelope system to one of the following: to receive probenecid (initial: 25 mg/kg/dose; maintenance: 10mg/kg/dose 4 x per day for 11 doses) and NAC (initial: 140mg/kg/dose; maintenance: 70mg/kg/dose 6 x per day for 17 doses) or the placebo via nasogastric (NG) or orogastric (OG) tube for 3 days. Placebo contents include equal volumes and dosing regimens of lactose powder (for opacity) suspended in Ora-Plus and normal saline.
