Antipsychosis Flashcards
Effects of low in dopamine
EPS
Weight gain
Major tranquilizers or neuroleptic drugs
Antipsychotic drugs
Class of antipsychotics that blocks d2 receptor only
Traditional
Class of antipsychotic drugs that blockes d2 and serotonin receptors
Non traditional
Arrange potency of antipsychotics
Butyrophenones = piperazine derivatives > piperidine > thioxanthenes»_space; aliphatics
About equally potent in d2 and serotonin blocking
Risperidone
Active metabolite of risperidone
Paliperidone
More potent as an antagonist of serotonin
Olanzapine
Partial agonist effect at d2 and 5ht1a receptors
Aripiprazole
Adverse effect of alpha adrenergic block
Orthostatic hypotention, failure to ejaculate, i potence
Dopamine receptor block
Extrapyramidal effects
Extrapyramidal side effects
Akathisia (uncontrolled restless ness)
Acute dystonia (spastic retrocollis/torticollis)
Parkinson’s syndrome
Dopamine receptor hypersensitivity
Tardive dyskinesia (abnormal choreoathetoid movements)
Prototype atypucal antipsychotic drug
Clozapine
The only atypical agent that is EPS free and TD (tardive dyskinesia free)
Clozapine
Reserved as last line due to risk of fatal and need for frequent laboratory testing
Clozapine
Long acting, depot antipsychotics (IM)
Fluphenazine, haloperidol decanoate
Theraphy for non compliant antipsychosis
Give long acting, depot antipsychosis if NR
Give clozapine if NR
Give addition of mood stab
Proven effective for refractory patients (antipsychotic)
Clozapine
Augmentation therapy of antipsychosis
Addition of mood stabilizing agents
General adverse effects of antipsychotics
Alpha adrenergic block
Dopaminergic block
Muscarinic block
Uncontrolled restlessness
Akathisia
