- Allopregnanolone
Allopregnanolone (also known as ALLO, AlloP, brexanolone, or Zulresso) is a naturally occurring neurosteroid which is made in the body from the hormone progesterone. As a medication, allopregnanolone is used to treat postpartum depression in adult women. It is given by injection into a vein.
Allopregnanolone acts as a positive allosteric modulator of the GABA-A receptor, the major biological target of the inhibitory neurotransmitter γ-aminobutyric acid (GABA). It has a wide variety of effects, including antidepressant, anxiolytic, stress-reducing, rewarding, prosocial, antiaggressive, prosexual, sedative, pro-sleep, cognitive, memory-impairment, analgesic, anesthetic, anticonvulsant, neuroprotective, and neurogenic effects.
