First-generation antipsychotic medications (FGAs), also known as neuroleptics or conventional antipsychotics, cause
High rates of extrapyramidal side effects (EPS), including rigidity, bradykinesia, tremor, and akathisia (restlessness).
They also frequently lead to tardive dyskinesia—hyperkinetic, involuntary movements most readily observed in the face and extremities.
38
MOA of SNRI's
The serotonin-norepinephrine reuptake inhibitors (SNRIs) appear to treat depression by initially blocking presynaptic serotonin and norepinephrine transporter proteins.
This inhibits reuptake of these neurotransmitters and leads to increased stimulation of post-synaptic receptors.
Side effects include nausea, dizziness, dry mouth, constipation, insomnia, and diaphoresis.
Watch out for patients with HTN!!

Lithium General info
First med specifically for Bipolar disorder (1940's)
Unknown why it works for mania
Levels should be measured
(watch for lithium toxicity)
Lithium levels are closely related to renal function, salt balance, and water balance.
Dehydration causes higher lithium levels,
increasing sodium intake causes lower lithium levels, and
decreased sodium intake causes an increase in serum lithium levels.
Lithium is contraindicated in patients with significant renal impairment, sodium depletion, dehydration, significant cardiovascular disease.
Excessive lithium levels can lead to toxicity with severe side effects and multisystem dysfunction which can be fatal if not recognized.
Side effects included Nausea, tremor, polyuria and thirst, weight gain, loose stools, and cognitive impairment

62
Bottom Line for Schizophrenia disorders
Patients treated with an antipsychotic for schizophrenia should be assessed prior to treatment if possible and at regular intervals for:
Signs of a movement disorder including extrapyramidal symptoms and tardive dyskinesia.
Symptoms of metabolic syndrome including measurements of body mass index, waist circumference, hemoglobin A1c, serum lipids, and blood pressure
ECG for patients with a history of cardiac disease or when starting an antipsychotic that prolongs the QT interval.
We recommend antipsychotic medication as first-line medication treatment for acute and maintenance phase treatment for schizophrenia.
For patients with schizophrenia who have recovered from an acute psychotic episode, we suggest that antipsychotic medication should be continued indefinitely at the lowest effective dose that achieves therapeutic goals. This approach is suggested even for patients who have achieved remission from a first psychotic episode.

95
Hallucinogen Therapy
We suggest that acute agitation and dysphoria from acute hallucinogen intoxication be managed with benzodiazepines.
Treatment options include midazolam, lorazepam, or diazepam
If psychotic features persist aggressive benzos and suggest haloperidol if persistent
Gastrointestinal (GI) decontamination via Charcoal is not necessary in the vast majority of cases.
96
Bipolar (maintenance)
The goals for maintenance therapy are to reduce subsyndromal symptoms, delay or prevent recurrence of new mood episodes, reduce the risk of suicide, and promote psychosocial functioning.
For most patients who respond to acute pharmacotherapy, we suggest maintenance treatment with the same regimen, rather than switching medications.
For patients who do not respond to or tolerate lithium, we suggest valproate, quetiapine, or lamotrigine rather than other medications.
For patients who do not respond to or cannot tolerate these drugs, aripiprazole, olanzapine, or risperidone are reasonable alternatives.
97
Children and adolescents with ADHD have an increased risk of
increased risk of substance use,
oppositional defiant disorder or conduct disorder,
intentional and unintentional injuries
increased risk of motor vehicle accidents
98
Benzodiazepines
Benzodiazepines exert their principal pharmacodynamic effect via CNS GABA receptors, potentiating the effects of endogenous GABA, the main inhibitory neurotransmitter.
Side effects of benzodiazepines include:
impairment of psychomotor performance, amnesia, dependence and withdrawal symptoms after long-term treatment, and rebound anxiety after short-term treatment.
Withdrawal and cognitive or learning impairment are more likely for persons taking higher doses.
99

103
Personality disorders (3 clusters)
Cluster A: Social detachment w/ unusual behavior
Cluster B Drama
Cluster C Anxious and fearful
104
Benzo MOA
Benzos potentiate GABA
at
GABA A receptors (benzodiazepine receptors)
Benzos bind at the GABA receptor separate from the GABA binding site and create an allosteric effect increasing action at the GABA receptor
This increases the length of time the that GABA activates the receptor
This allows Chloride to enter the neuron
This hyperpolarizes the neuron and makes it less likely the neuron will fire
(i.e. inhibits the firing of neurons through GABA)
105
Stimulants Methamphetamine
Methamphetamine —
The reinforcing effects of methamphetamine are mediated both by blockade of the dopamine transporter and by stimulating the presynaptic release of dopamine.
