nocturnal enuresis
what is a specific clinical application of tricyclic antidepressant clomipramine
OCD
what is the mechanism of action of tricyclic antidepressants
inhibit reuptake of 5-HT and NE from the synaptic cleft by respectively block 5-HT and NE reuptake transporters, thereby causing enhancement of postsynaptic responses

what is serotonin syndrome characterized by
hyperthermia, muscle rigidity, myoclonus, and rapid fluctuations in mental status and vital signs
what GI distress is sertraline most often associated with
diarrhea
what GI distress is paroxetine most often associated with
constipation
what are SSRIs used as first line treatment for
depression, anxiety, OCD
what do TCAs with secondary amines preferentially affect
NE system
what do TCAs with tertiary amines preferentially affect
5-HT system
what is the clinical application of venlafaxine, duloxetine
depression, anxiety, panic disorder with or without agoraphobia
what is the clinical application of dexveniafaxine
major depressive disorder
what is the clinical application of milnacipran
fibromyalgia
what is the clinical application of atomoxetine
ADHD
what is the clinical application of bupropion
depression, smoking cessation
what are the SNRIs
venlafaxine and duloxetine; desvenlafaxine; milnacipran
how does venlafaxine act at low concentrations
SSRI by increasing serotonin levels
how does venlafaxine act at high concentrations
also increases NE levels
what does duloxetine inhibit
NE and 5-HT reuptake
what is the active metabolite of venlafaxine
desvenlafaxine
what does milnacipran inhibit
NE and 5-HT reuptake
what SNRI can cause increased serum cholesterol and triglycerides
desvenlafaxine
what is the mechanism of action of atomoxetine
selectively block NE transporter, leading to increased NE levels
what are some adverse effects seen with atomoxetine
dysmenorrhea, MI, prolonged QT interval, seizures
what is the mechanism of action of bupropion
aminoketone antidepressant that weakly inhibits neuronal uptake of 5-HT, dopamine and NE
what is the mechanism of action of mertazapine
blocks 5-HT2a, 5-HT2c, and the alpha2-adrenergic auto receptor and presumably decreases neurotransmission at 5-HT2 synapses while increasing NE neurotransmission.
what is the mechanism of action of nefazodone and trazodone
block postsynaptic 5-HT2 receptors
what are some contraindications for bupropion use
seizures; electrolyte abnormalities; bulimia/anorexia
what medication has the fewest sexual effects among antidepressant agents

what is trazodone used principally as
somnorific

what are some adverse rxns seen with ketanserin
orthostatic hypotension, ventricular tachycardia, flushing, fluid retention
what is the mechanism of action of ketanserin
5-HT2a/2c antagonist
what is ketanserin used primarily for
topically to reduce intraocular pressure in glaucoma
what is the mechanism of action of ondansetron
5-HT3 antagonist
what medication is a potent antiemetic that is frequently used as an adjunct to cancer chemotherapy or in cases of refractory nausea
ondansetron
what are some adverse reactions seen with ondansetron
