Neuroleptics (decrease DA) - for Schizophrenia Flashcards
1st generation (typical or atypical?)
“Typical”
Chlorpromazine
1st gen antipsychotic, antagonize D2 receptors. Low potency, also H1 antagonist (dry mouth, constipation)
Fluphenazine
1st gen antipsychotic, D2 antagonist - high potency (Schizophrenia)
Trifluoperazine
1st gen antipsychotic, D2 antagonist - high potency (Schizophrenia)
Perphenazine
1st gen antipsychotic, D2 antagonist - high potency (Schizophrenia)
Thiothixene
1st gen antipsychotic, D2 antagonist - high potency (Schizophrenia)
Haloperidol
1st gen antipsychotic, D2 antagonist - high potency (Schizophrenia)
Tetrabenazine
VMAT2 inhibitor = Domamine-depleting in synapse (for huntington’s and tardive dyskinesia. occasionally used for schizophrenia)
Dantrolene
Direct muscle relaxant (for malignant hyperthermia associated with NMS) - NMS (neuroleptic malignant syndrome is side effect of neuroleptics)
2nd generation neuroleptics (typical or atypical?)
“Atypicals”. Pines, Dones, and Rips
Pines: more sedating b/c more antihistamine activity and more metabolic syndrome inducing
Drones: more EPS
Rips: only one (Aripiprazole), less weight side effects
Clozapine
D2 (& D1 & D4) receptor antagonist, and 5-HT receptor antagonist, and NMDA antagonist. For schizophrenia when other drugs don’t work, must monitor WBC. 2nd gen neuroleptic
Olanzapine
D2 antagonist, 5-HT antagonist (lessens EPS risks). For schizophrenia. halts mania. 2nd gen neuroleptic
Quetiapine
D2 antagonist, 5-HT antagonist (lessens EPS risks). For schizophrenia. halts mania. 2nd gen neuroleptic
EPS
Extrapyramidal syndrome: when DA forced too low => Akathesia, Dystonia, Parkinsonism, NMS (neuroleptic malignant syndrome = hyperthermia, muscle rigidity, vital sign instability, and Rhabdomyolysis)
NMS
Neuroleptic Malignant Syndrome: When DA forced too low => hyperthermia, muscle rigidity, vital sign instability, and Rhabdomyolysis (also EPS)
