Brief Summary:
Traumatic brain injury (TBI) is an important public health problem with an estimated 1.7 million new cases in the United States each year. Although the vast majority of these victims sustain mild TBI, many still develop headache, difficulty concentrating, and decreased memory with potential for serious long-term consequences. In particular, mild TBI is an important consequence of combat-related injuries sustained by military personnel and sports-related injuries in young adults. Unfortunately, treatment of mild TBI is usually limited to oral analgesics for headache pain such as acetaminophen (Tylenol) or ibuprofen (Motrin or Advil). Since there are no previous randomized trials of these medications for mild TBI, their comparative effectiveness is not known. Increasing animal based evidence suggests that mild TBI is related to brain cell injury caused by overexpression of a cellular enzyme (COX-2) that causes neuroinflammation. Fortunately, inhibition of COX-2 is easily achieved using ibuprofen. We hypothesize that head injured patients treated with ibuprofen will have a lower incidence of mild TBI symptoms than patients treated with acetaminophen. We will conduct a randomized clinical trial to measure the comparative effects of ibuprofen versus acetaminophen on the incidence of specific symptoms of mild TBI in emergency department patients with head injury.

Arm Intervention/treatment
Experimental: Ibuprofen
Ibuprofen is a nonselective NSAID that inhibits both COX-1 and COX-2 isoenzymes. COX-2 inhibition prevents arachidonic acid from converting to vasoactive prostaglandins and reactive oxygen species in brain cell. The analgesic, antipyretic, and antiinflammatory activity of ibuprofen operates mainly through inhibition of COX-2. The experimental treatment oral doses of either ibuprofen (800 mg three times per day). Subjects will receive the first medication dose in the emergency department and will be given the remaining 5 doses to take over 48 hours as outpatients.
Drug: Ibuprofen
Ibuprofen 800 mg orally three times per day for two days for study subjects who are randomized to the ibuprofen arm.
Other Name: motrin

Active Comparator: Acetaminophen
Acetaminophen is a poor inhibitor of both COX isoenzymes in the CNS and has significantly weaker antiinflammatory effects than NSAIDs. Acetaminophen does not inhibit COX in peripheral tissues and is less effective in the presence of peroxides. The active comparator treatment is oral doses of acetaminophen (1000 mg three times per day). Subjects will receive the first medication dose in the emergency department and will be given the remaining 5 doses to take over 48 hours as outpatients.
Drug: Acetaminophen
Acetaminophen 1000 mg orrally three times per day for two days for subjects who are randomized to the acetaminophen arm.
Other Name: tylenol

Primary Outcome Measures :
  1. Post-concussion symptoms [ Time Frame: 7 to 14 days after enrollment. ]
    The main outcome variables will be the incidence of post-concussion symptoms that will be measured using NIH Common Data Elements and Neuro-QOL instruments. The Neuro-QOL instruments were developed for the NIH by the Northwestern University Department of Medical Social Sciences to provide clinically relevant and psychometrically robust health-related quality of life assessment tools for patients with common neurological disorders. In addition, the Neuro-QOL measurement system provides item banks and short forms that enable patient reported outcome measurement in neurological research which minimizes patient burden.41-44 This information will be collected at 7 to 14 days after initial ED evaluation. Emphasis will be placed on the Neuro-QOL instruments that measure headache pain and cognitive function as these are the most common and concerning symptoms of mild TBI.

Secondary Outcome Measures :
  1. Adverse drug reactions [ Time Frame: 7 to 14 days after enrollment ]
    Information regarding adverse drug reactions (ADRs) will also be obtained during the follow up interview of the study subjects. This assessment will include questions regarding abdominal pain or discomfort and any allergic reaction (e.g., rash, swelling, or difficulty breathing).
