Tirzepatide attenuates alcohol-induced dopamine release in the nucleus accumbens and induces sustained synaptic depression in the lateral septum.
Tirzepatide's effect on alcohol reward involves reducing dopamine release in the nucleus accumbens and altering synaptic plasticity in the lateral septum.
GoodSupportsHIGH confidence
Tirzepatide pretreatment substantially reduced this alcohol-induced dopamine response... Tirzepatide exposure 24 hours earlier produced a sustained suppression of evoked field potentials... indicative of a decreased probability of neurotransmitter release.
Why this rating
Strong preclinical evidence using microdialysis and electrophysiology.
