D) activation of dopamine D₂ receptors.

Question

Quizplus · Accepted Answer

Alcohol shares several pharmacological mechanisms with inhalants, including positive modulation of GABAA receptors, antagonism of 5-HT₃ receptors, and antagonism of NMDA receptors. However, direct activation of dopamine D₂ receptors is not a common action shared with alcohol; alcohol's effects on dopamine levels are more indirect, primarily through modulation of other neurotransmitter systems.
