Allopregnanolone, a natural metabolite of the gondal steroid progesterone, is a neurosteroid that acts as a positive modulator of synaptic and extrasynaptic GABA-A receptors and exerts effects without the development of tolerance.

Researcher Mike Rogawski at the University of California, Davis developed an intravenous formulation of allopregnanolone that is being studied as a treatment for traumatic brain injury.  The formulation was provided on an emergency use basis to stop treatment-resistant status epilepticus (non-stop seizures) in patients in intensive care who had been unresponsive to all medications and were placed in a barbiturate coma. When barbiturates were stopped, their seizures returned. All four intensive care patients who were treated with allopregnanolone had their status epilepticus cease and were able to go home. This included a 23-year-old who had been hospitalized with refractory status epilepticus for over 90 days.
