Comprehensive Clinical Pharmacology and Mechanistic Guide to Antipsychotic Medications, Dopamine Pathways, Adverse Effects, EPS, Metabolic Risks, and Schizophrenia Management Strategies Complete Questions Provided with Verified A+ Graded Rationales Latest Updated 2026 Mesolimbic Pathway Which Dopamine Pathway: -DA travels from midbrain tegmental area to nucleus accumbens • Increased DA activity in this pathway may cause delusions, hallucinations, and other “positive symptoms” Mesocortical Pathway Which Dopamine Pathway: • Decreased DA activity in the pathway that goes from midbrain to prefrontal lobe cortex can cause apathy, withdrawal, lack of motivation, and other “negative symptoms” Nigrostriatal Pathway Which Dopamine Pathway: -This pathway from the substantia nigra to the striatum coordinates body movements • Inhibition of DA in this area causes extrapyramidal side effects (EPS) side effects of antipsychotics NMDA __________ receptor inhibitors result in cognitive impairment and psychosis (e.g. pcp and ketamine) Schizophrenia primary use of antipsychotics Positive Antipsychotics primarily reduce ________________ symptoms Use of antipsychotics for dementia-related psychosis is associated with an increased risk for death (cardiovascular or infectious) in elderly patients BW for Antipsychotics Dopamine (D2) Receptor Antagonists General MOA for all 1st gen and most of 2nd gen antipsychotics Alpha 1 Adrenoceptors Blockade of _________________________________: AEs: -Dizziness -Orthostatic hypotension -Reflex tachycardia D2 Receptors Blockade of _________________________________: -alleves positive symptoms of schizophrenia AEs: -Extrapyramidal effects -Elevated serum prolactin levels D4 Receptors Blockade of _________________________________: -Alleves negative symptoms of schizophrenia and decreases incidence of extrapyramidal side effects H1 Receptors Blockade of _________________________________: -sedation AEs: -Drowsiness -Increase in appetite and weight Muscarinic Receptors Blockade of _________________________________: AEs: -Blurred vision -Constipation -Dry mouth -Urinary retention Serotonin 5-HT2 Receptors Blockade of _________________________________: -Alleves negative symptoms of schizophrenia and decreases the incidence of extrapyramidal side effects AEs: -anxiety -Insomnia First Gen Antipsychotics -Chlorpromazine -Haloperidol -Perphenazine Second Gen Antipsychotics -Aripiprazole -Asenapine Second Gen Antipsychotics -Brexpiprazole -Cariprazine Second Gen Antipsychotics -Clozapine -Iloperidone -Lurasidone -Olanzapine -Paliperidone ER Second Gen Antipsychotics -Quetiapine
