Biochem/physiol Actions: 5β-Pregnan-3α-ol-20-one or pregnanolone is a neurosteroid that acts as a positive allosteric modulator (PAMs) of γ-aminobutyric acid A receptors (GABAARs). It mediates anti-convulsive, anxiolytic and sedative effects. Pregnanolone inhibits γ-aminobutyric acid C receptor (GABAC) receptor-based response and favors GABAA receptor-mediated currents.
