How Buspar Affects Neurotransmitters
How Buspar Works
Buspirone is a partial agonist at serotonin 5-HT1A receptors — both presynaptic (reducing serotonin release initially) and postsynaptic (stimulating serotonin signaling). This mechanism produces anxiolytic effects without sedation, cognitive impairment, or addiction potential.
