AP PSYCHOLOGY

Detailed explanation-1: -Typical antipsychotics exert their action predominantly through dopamine D2 receptor antagonism.

Detailed explanation-2: -Most antipsychotic drugs are known to block some of the dopamine receptors in the brain. This reduces the flow of these messages, which can help to reduce your psychotic symptoms. Affecting other brain chemicals. Most antipsychotics are known to affect other brain chemicals too.

Detailed explanation-3: -The neurotransmitters affected include dopamine, noradrenaline, and serotonin. Dopamine is the primary neurotransmitter affected by taking antipsychotics; an overactive dopamine system may be one cause of the hallucinations and delusions commonly experienced during psychosis.

Detailed explanation-4: -Dopamine Receptor Antagonists: Typical Antipsychotics The antipsychotic effects of these medications are thought to be mediated through the inhibition of dopamine binding at dopamine D2 receptors, resulting in the reduction of dopaminergic neurotransmission in the central nervous system (CNS).

Detailed explanation-5: -Second-generation antipsychotics such as Risperdal (risperidone), Geodon (ziprasidone), and Invega (paliperidone) are all potent antagonists of dopamine D2 receptors, while Clozaril (clozapine) and Seroquel (quetiapine) are weak D2 antagonists.
