Schizophrenia Flashcards
(72 cards)
What is the sx of schizophrenia
Hallucinations
Delusions
Disorganized thinking/behaviors
Neurotransmitters involved with schizophrenia
Dopamine, Serotonin, Glutamine
What are the negative sx of schizophrenia?
Lack of emotion (apathy)
Social withdrawal
Loss of motivation (avolition)
Lack of speech (alogia)
What are the positive sx of schizophrenia
Hallucination
Delusions
Disorganized thinking/behaviors
Drugs that cause psychotic sx?
Illicit/recreational drugs
First line for schizophrenia
2nd Antipsychotics > 1st gen → lower risk for EPS
EPS sx
Dystonia (muscle contractions)
Dyskinesias (abnormal movements)
Tardive dyskinesia (repetitive, involuntary movements)
Akathisia (restlessness, inability to remain still)
Due to adherence being low, what are formulations that a good for schizophrenics?
Long-acting injections
ODT
Oral solutions/suspensions
Acute IM injections
What is the BBW of all antipsychotics
Not indicated for agitation control in elderly patients with dementia-related psychosis → ↑ mortality
What is blocked by 1st gen antipsychotics
D2 receptors →with minimal serotonin receptor blockade
1st gen that causes QTc prolongation
Thioridazine, haloperidol, chlorpromazine
ADR of 1st gen antipsychotics
QTc prolongation, orthostasis/falls
CNS depression
EPS
Hyperprolactinemia → infertility, ED, galactorrhea
NMS
Sedation, Dz, anticholinergics
How to mitigate EPS sx and dystonic reactions?
Give anticholinergic (benzotropine, benadryl)
Difference between lower and higher potency 1st gen
Lower: ↓ EPS and ↑ sedation
Higher: ↓ sedation and ↑ EPS
Low potency 1st gen
Chlorpromazine
Thioridazine
Medium potency 1st gen
Loxapine
Perphenazine
High potency 1st gen
Haloperidol
Fluphenazine
Thiothixine
Trifluoperazine
Activity of 2nd gen
Blocks D2 and 5-HT2A receptors
Aripiprazole
Abilify
ADR of Abilify
Akathesia, activating
Dosing form of Aripiprazole
IM, ODT, tablet
BBW of clozapine
Neutropenia/agranulocytosis
Myocarditis, cardiomyopathy
Seizures
No longer in REMs
ADR of clozapine
Agranulocytosis, seizures, constipation, weight gain, hyper salivation
Start at ANC ≥1500 → Check Q6W
Stop if ANC <1000
Despite being effective why is clozapine last line
Severe ADR profile bu low EPS/TD
