On progesterone treatment
The group assigned to progesterone treatment.
group assigned to placebo
The group that will not be receiving progesterone treatment
Blood samples will be drawn on traumatic brain injury patients who are participating in the ProTECT III study just prior to the initiation of the study drug infusion and 24 and 48 hours from the time they are enrolled in the study to test for biomarkers that may help predict how severe the injury is and how well they improve. The investigators will also test to see if the study medication is being absorbed and is staying at a consistent level in the blood stream.
|Ages Eligible for Study:
||18 Years and older
|Genders Eligible for Study:
