What is MOA of first generation antipsycotics?
Block dopamine type 2(D2) post synaptic receptors more than 5HT2
- a lot end in -azine
29
- Muscarinic receptors
- Histaminic receptors (H1)
- Alpha-adrenergic receptors (a1)
- D2 receptors
are blocked by what antipsychotic?
First generation antipsychotics
-D2 receptors are involved in the nigrostriatal pathways and tuberoinfundibulnar pathways creating side effects of EPS movements and prolactin increase respectively
30
hyperprolactemia --> (amenorrhea/galactorrhea/gynecomastia/decreased libido)
And Extrapyramidal sx/ tardive dyskinesia are side effects of what?
Dopamine associated SE of first generation antipsychotics
31
What receptors are blocked by first generation antipsychotics
- Muscarinic receptors--> dry mouth, constipation, urinary retention, blurred vision
- Histaminic receptors (H1)--> sedation
- Alpha-adrenergic receptors (a1)--> orthostatic hypotension, dizziness/syncope
- D2 receptors
also rish of QT prolongation and seizure activity
32
What is the MOA of Second generation antipsychotics? (2)
1. Block D2 dopamine post synaptic receptors
2. Block 5HT(2A)
***SGAs are stronger 5HT(2A) receptor blockers than D2 receptors****
33
What does suffix -idone indicate?
A second generation antipsychotic that is a
1. 5HT-2A antagonist
2. DA antagonist
```
Iloperidone
Lurasidone
Paliperidone
Risperidone
Ziprasidone
```
(Lurasidone is also partial 5HT-1A agonist
34
What does suffix -piprazole indicate?
a second generation antipsychotic that is a
1. Partial DA receptor agonist
2. 5HT-1A agonist
Aripiprazole
Brexpiprazole
35
What does suffix -apine mean?
Multi-Acting receptor- target Agent second generation antipsychotic
```
Asenapine
Clozapine
Olanzapine
Quetiapine
Lumateperone
```
36
What second generation antipsychotic is an inverse serotonin agonist/antagonist?
Pimavanserin --> to treat Parkinson psychosis
37
What are second generation antipsychotic side effects?
1. weight gain
2. Metabolic effects--> hyper glycemic and hyperlipidemia
3. QT prolongation and ECG changes--> greater risk for women, elderly and those on antiarrhythmics
4. Stroke--> greater risk in elderly with dementia
38
What FGA have high risk of Tardive Dyskinesia?(3)
1. Clorpromazine
2. Fluphenazine
3. Haloperidol
39
What FGA have a high risk of prolactin elevation (amenorrhea, galactorrhea) and extrapyramidal sx? (2)
1. Fluephenazine
| 2. Haloperidol
40
What FGA has the most adverse side effects including:
- Tardive dyskinesia
- Sedation
- Anticholinergic Side effects
- Orthostatic hypertension
- QTc prolongation
Chlorpromazine
41
What FGA has a low risk of EPS and tardice dyskinesia but a high risk of anticholinergic side effects and orthostatic hypotension?
Thioridazine
42
What second generation antipsychotic agent has the lowest risk of all adverse side effects?
Aripiprazole
43
What second generation antipsychotic agents has a high risk of:
- weight gain
- Hyperglycemia
- hyperlipidemia
- sedation
- anticholinergic side effects*
Clozapine
| Olanzapine is high risk in all of these except cholinergic side effects
44
What second generation antipsychotic is mostly low risk of side effects?
Lurasidone
45
What second generation antipsychotic agents has a high risk of (1):
- weight gain
- Hyperglycemia
- hyperlipidemia
- sedation
Olanzapine (no cholinergic effects is only difference from clozapine)
46
What SGA has a high risk of hyperlipidemia and sedation?
Quetiapine
47
What SGA has an increased risk of prolactin elevation but not really any other side effects?
Risperidone
48
What 2 SGAs have the highest risk of metabolic effects such as weight gain, hyperglycemia, and hyperlipidemia?
Cariprazone

Ziprasidone
50
What needs to be consistently monitored in patients on second generation antipsychotics?
- Medical and family hx including CV disease
- Weight
- Waist circumference
- blood pressure
- fasting glucose level
fasting lipid profile
51
Agranulocytosis can be seen in what second generation antipsychotic?

52
What Second generation antipsychotic increases the risk of Drug Reaction w/ Eosinophilia and Systemic Symptoms(DRESS)?

dehydration
54

Dantrolene

Clozapine
56
