Allopregnanolone is a selective activator of GABA-A receptor with the concentration of 10 nM . GABA-A receptor is a pentameric transmembrane receptor and sits in the membrane of neuron. As a subtype of receptor for the neurotransmitter GABA, GABA-A receptor mediates the bulk of synaptic inhibition in the central nervous system and prevents action potential generation by short-circuiting the depolarization produced by excitatory neurotransmission. It has been shown that allopregnanolone can directly activate GABA-A receptor and it also can allosteric enhance GABA-evoked currents to function . Allopregnanolone is an agonist for GABA-A receptor. When tested with rat retinas exposed to hydrostatic pressure (75 mm Hg) for 24 hours, administration of alloprenanolone significantly suppressed pressure-induced axonal swelling via functioning on GABA-A R in a dose-dependent manner . In spinal cord slides from naïve rats, pre-incubation with TGOT significantly lower the following allopregnanolone (0.11 ± 0.04 ng/mg) treatment thus decayed GABA-A R which resulted in the spinal neurosteroidogenesis . It is also reported that subcutaneously injected allopregnanolone to male Wistar rats once daily over five consecutive days resulted in energy intake and weight gain increasement .
