25
Which generation of antipsychotics blocks both dopamine (positive symptoms) and serotonin (negative symptoms) receptors
Second generation (atypical)
26
Which generation of antipsychotics is used for long term treatment of schizophrenia
Second generation (atypical)
27

30
degrades biogenic amine neurotransmitters (eg, serotonin, dopamine, norepinephrine, epinephrine)
Monoamine oxidase
31
inhibit the enzymatic activity of monoamine oxidase and thereby increase the synaptic concentrations of these neurotransmitters
Monoamine oxidase inhibitors (MAOIs)
32
MAOIs are effective for depression and anxiety but are typically used only after other agents have failed because of the risk for what serious adverse effects?
1. Hypertensive crisis - MAOIs decrease peripheral degradation of tyramine (which normally gets degraded by MAO) --> hypertensive crisis can result from tyramine displacing stored monoamines such as dopamine, norepinephrine, and epinephrine from synaptic vesicles 2. Serotonin syndrome - Combining MAOIs with other serotonergic agents increases the risk for serotonin syndrome
