NR 546 Week 3 Assignment-Antipsychotic Medications-comprehensive-2022-2023
Chamberlain college of nursing
Drug name Indication
Target symptoms: state if positive or negative effect Potency (if noted. receptor occupancy if noted ) Neurotransmitter(s) affected Half-life (T1/2), metabolism (CYP 450
enzyme) Notable side effects (associate to pathway or NT)
Typical antipsychotics (conventional)
Haloperidol Blocks dopamine 2 receptors, reducing positive symptoms of psychosis and possibly combative, explosive, and hyperactive behaviors Blocks dopamine 2 receptors in the nigrostriatal pathway, improving tics and other symptoms in Tourette’s syndrome. Decanoate half-life approximately 3 weeks Oral half-life approximately 12–38 hours Acute blockade of dopamine 2 receptors in the striatum can cause drug-induced parkinsonism, dystonia, or akathisia
Chronic blockade of dopamine 2 receptors in the striatum can cause tardive dyskinesia
By blocking dopamine 2 receptors in the pituitary, it can cause elevations in prolactin By blocking dopamine 2 receptors excessively in the mesocortical and mesolimbic dopamine
pathways, especially at high doses, it can cause worsening of negative and cognitive symptoms (neuroleptic-induced deficit syndrome).
Blocking alpha 1 adrenergic receptors can cause
dizziness, hypotension, and syncope
Thioridazine Blocks dopamine 2 receptors, reducing positive symptoms of psychosis Metabolized by CYP450 2D6 Acute blockade of dopamine 2 receptors in the striatum can cause drug-induced parkinsonism, dystonia, or akathisia.
Chronic blockade of dopamine 2 receptors in the striatum can cause tardive dyskinesia
By blocking dopamine 2 receptors in the pituitary, it can cause elevations in prolactin By blocking dopamine 2 receptors excessively in the mesocortical and mesolimbic dopamine
pathways, especially at high doses, it can cause worsening of negative and cognitive symptoms (neuroleptic-induced deficit syndrome) Blocking muscarinic cholinergic receptors can
