NCT02549716

Brief Summary

This study compares the bioavailability of IV and PO acetaminophen in both blood and the cerebrospinal fluid (CSF) of patients following subarachnoid hemorrhage. The study will also compare the temperature and levels of inflammatory cytokines in both blood and CSF of patients treated with IV and PO acetaminophen.

Outcome Measures

Primary Outcomes (1)

  • Bioavailability of Acetaminophen in Cerebral Spinal Fluid (CSF) and Blood

    Patients in both IV and PO groups will have samples taken from their Cerebral Spinal Fluid (CSF) and blood at the above times after acetaminophen is administered for the first time. They will then have additional samples taken every 24 hours following the time of first drug administration for 14 days. Patients will also have a sample collected every 35 hours (1 hour before the 6th loading dose) to determine the steady state level of acetaminophen.

    Time = 0, 5, 15, 30, 45, 60, 90, 120, 180, 240, and 360 minutes after first drug administration

Secondary Outcomes (3)

  • Concentrations of Interleukin-1 (IL-1), Interleukin-6 (IL-6), and Thromboxane A-2 (TXA-2) in Cerebral Spinal Fluid (CSF) and Blood

    Time = 0, 5, 15, 30, 45, 60, 90, 120, 180, 240, and 360 minutes after first drug administration. Additionally, every 24 hours after time t=0 for 14 days (14 additional samples from both blood and CSF).

  • Number of Febrile Periods

    Time = 0, 5, 15, 30, 45, 60, 90, 120, 180, 240, and 360 minutes after first drug administration. Additionally, every 24 hours after time t=0 for 14 days (14 additional samples from both blood and CSF).

  • Incidence of Vasospasm

    Days 0-14 following diagnosis with subarachnoid hemorrhage.

Study Arms (2)

IV acetaminophen + oral placebo

EXPERIMENTAL

Patients in this group will receive IV acetaminophen and an oral placebo. The IV formulation will be given using the FDA approved OFIRMEV which comes in a single glass bottle at a concentration of 1000mg/100ml (10mg/ml) containing a total of 1 gram of acetaminophen.

Drug: IV acetaminophenDrug: Oral placebo

Oral acetaminophen + IV placebo

EXPERIMENTAL

Patients in this group will receive oral acetaminophen and a saline solution placebo through their IV. The enteral formulation will be in the standard tablet form of 500mg per pill. Patients will receive two pills, or 1 gram of acetaminophen.

Drug: Oral acetaminophenDrug: IV placebo

Interventions

Patients in this group will receive IV acetaminophen and an oral placebo every 6 hours for a 14 day period. Blood and CSF samples will be collected from patients throughout the 14 day period.

Also known as: Ofirmev, IV paracetamol
IV acetaminophen + oral placebo

Patients in this group will receive oral acetaminophen and an IV saline solution placebo every 6 hours for a 14 day period. Blood and CSF samples will be collected from patients throughout the 14 day period.

Also known as: Tylenol, paracetamol
Oral acetaminophen + IV placebo

Patients who receive IV acetaminophen will also receive an oral placebo with their IV treatments (every 6 hours for a 14 day period).

Also known as: placebo
IV acetaminophen + oral placebo

Patients who receive oral acetaminophen will also receive a saline solution placebo at the same time that they receive the oral acetaminophen treatment (every 6 hours for 14 days).

Also known as: placebo, saline solution
Oral acetaminophen + IV placebo

Eligibility Criteria

Age18 Years+
Sexall
Healthy VolunteersNo
Age GroupsAdult (18-64), Older Adult (65+)

You may qualify if:

  • Diagnosis of subarachnoid hemorrhage (must be confirmed by CT, CT angiography, lumbar puncture, or MRI).
  • Fisher Grade between 1-3 (subarachnoid blood without signs of intraventricular hemorrhage or parenchymal extension).
  • Placement of an external ventricular drain.
  • Adults aged 18-100 years.

You may not qualify if:

  • Anyone under the age of 18 or over the age of 100.
  • Adult patients with subarachnoid hemorrhage with interventricular hemorrhage or parenchymal extension (Fisher Grade 4).
  • Contraindication to acetaminophen such as a known hypersensitivity, severe hepatic impairment, or severe active liver disease.
  • Severe renal impairment (creatinine clearance ≤ 30 mL/min).
