Wolters Summary - Antipsychotics Flashcards
BBW antipsychotics
elderly patients w/dementia psychosis have increased risk of death
FGA summary
more likely to have EPS, TD
ONLY positive
SGA summary
less likely to have EPS, TD
negative AND positive
antipsychotics S.E.
sedation anticholinergics orthostatic hypOtension E.P.S. T.D. QT prolongation Seizure Agranulocytosis Endocrine weight gain sexual dysfunciton
Tardive dyskinesia
abnormal, involuntary orofacial movements
DON’T give anticholinergics
EPS symptoms
parkinsonism
dystonia
akathisia
tardive duskinesia
parkinsonism
bradykinesia, rigidity, tremor, akinesia
responses to anticholinergics (diphenhydramine, trihexyphenidyl,bentropine)
dystonia
torticollis, larynogospasm
give anticholinergics
akathisia
somatic restlessness, inability to stay calm
esp. in legs
responds poorly to anticholinergics – B-blockers instead
endocrine S.e. of antipsychotics
prolactin secretion
galactorrhea, menstrual changes
NMS
any drug causing dopamine antagonism
hyperthermia, muscle rigidity, encephalopathy, autonomic instability
elevated CK from muscle rigidity
dantrolene given to decrease muscle rigidity (hepatotoxic)
TOP FGA (5)
- Chlorpromazine
- Fluphenazine (Prolixin)
- Haloperidol (Haldol)
- Loxapine
- Thiothixene
IM FGA
- Chlorpromazine
- Fluphenazine (Prolixin)
- Haloperidol (Haldol)
LAI FGA
Fluphenazine (Prolixin)
Haloperidol (Haldol)
oral FGA
loxapine
t or f IV Haldol is common practice
FALSE
although seen, not FDA approved
QTc prolongation S.e.
FGA s.e. trends
most of the FGAs cause weight gain
more EPS and prolactin elevation
chlorpromazine s.e.
hypercholesterolemia (highest of FGA)
anticholinergics s.e.
othrostatic hypotension
therefore least likely to be used
highest cause of anticholinergic s.e. and othrostatic hypotension of FGA
thiothixene
Haloperidol
(Fluphenazine)
brand
Haldol
Prolixin
SGA main
- Aripiprazole (abilify)
- Lurasidone (Latuda)
- Olanzapine (Zyprexa)
- Paliperidone (invega)
- Quetiapine (Seroquel)
- Risperidone (Risperidal)
- Ziprasidone (Geodon)
- Clozapine

Paliperidone (invega)
IM SGA
Olanzapine (Zyprexa)
Aripiprazole (abilify)
Ziprasidone (Geodon)
SGA most likely to cause EPS/Prolactin elevation
paliperidone
risperidone
SGA with highest weight gain/hypercholesteremia
clozapine
olanzapine (Zyprexa)
antipsychotics and QTc prolongation
IV Haldol
Ziprasidone
Aripiprazole
(abilify)
Lurasidone
(Latuda)
Olanzapine
(Zyprexa)
Paliperidone
(invega)
Quetiapine
Seroquel
Risperidone
(Risperidal)
Ziprasidone
(Geodon)
aripiprazole MOA
dopamine D1 and 5HT1 agonist
5HT2 antagonist
serotonin activity and dopamine activity
lurasidone/latuda beneficial efects
theorized to have beneficial cognitive and anxiolytic effects
acute agitation
FGA and SGA are of equal efficacy
use with benzos
CATIE trial
difference in effectiveness between FGA and SGA are not as much as we thought
PORT recommendations
for first episode of schizophrenia
use any other agent but clozapine
pregnancy and antipsych
clozapine/olanzapine can cross into the breast milk
geriatric and antipsych
avoid sedation and othrostatic hypotension
more prone to QTc
