Antipsychotics Flashcards
typical antipsychotic
blocks D2 receptors
SE: failure of ejaculation, marked sedation, CORNEAL & LENS DEPOSITS, neuroleptic malignant syndrome, contact dermatitis, decreased seizure threshold
chlorpromazine
thiothexene
brand name: thorazene
typical antipsychotic blocks D2 receptors for anti-emesis SE: failure of ejaculation, retinal deposits, cardiotoxicity (QT prolongation - arrythmias in prototype) STRONGEST AUTONOMIC EFFECTS ONLY ANTIPSYCHOTIC WITH FATAL OVERDOSE
thioridazine
fluphenazine, perphenazine, prochlorperazine, trifluoroperazine
typical antipsychotic blocks D2 receptors SE: EPS, NEUROLEPTIC MALGINANT SYNDROME WEAKEST AUTONOMIC EFFECTS LEAST SEDATING among typical antipsychotics
haloperidol
droperidol
atypical antipsychotic blocks 5-HT receptors for REFRACTORY, SUICIDAL schizophrenia SE: weight gain, hyperglycemia, hyperlipidemia, myocarditis, AGRANULOCYTOSIS, seizures, ileus, hypersalivation (sialorrhea) REDUCES RISK OF SUICIDE
