Allopregnanolone targets which receptor?

Explanation:
Allopregnanolone acts as a neurosteroid that potentiates GABA-A receptor activity. It binds to an allosteric site on the GABA-A receptor and enhances the effect of GABA, increasing chloride influx, which hyperpolarizes neurons and strengthens inhibitory signaling. This mechanism produces sedative, anxiolytic, and anticonvulsant effects. It does not target NMDA receptors, dopamine D2 receptors, or serotonin 5-HT2A receptors, which belong to different neurotransmitter systems. The take-home is that allopregnanolone’s main action is to boost GABA-A–mediated inhibition.
