Antidepressants
Tricyclic and heterocyclins SSRI/SSNRI/MAOI
Tricyclics and Heterocyclics
MOA Increase the level of monoamines in the synapse by reducing the reuptake of norepineprine and serotonin. Warning narrow therapeutic window, overdose causes fatal arrhytmias
SSRI and SSNRI
Most commonly used antidepressants today. Major side effects: GI disturbances and sexual dysfunction
MAOI
More helpful in depression with atypical features. Not commmonly used bc a tyramine-free diet (no red wine or aged cheese) must be followed or a hypertensive crisis can results
Lithium (side Effects)
Tremor, polyuria/diabetes insipidus, acne, hypothyroidism, cardia dysrhythmias, weight gain, edema, leukocytosis. * cleared through kidney*
Valproic acid (warning
Teratogenic
1st generation antipsychotics (typical)
MOA: block central dopamine receptors. Most effective in reducing the positive symptoms of schizophrenia (ex. Hallucinations and delusions)
Tricyclics and Tetracyclics (side effects)
Anticholinergic: dry mouth, blurry vision, urinary retention, constipation, sedation, orthostatic hypotension (alpha blocaked), tachycardia, prolonged QT, weight gain. Fall risk in elederly. Half life: 6-30 h.
Amitriptyline
Tertiary amine. Highly anticholinergic, very sedating. Half life 20 h
Doxepin
Tertiary amine. Highly anticholinergic, very sedating. Half life 16 h
imipramine
tertiary amine. Highly anticholinergic. Half life 20 h
Clomipramine
Tertiary amine. Anticholinergic, sedating, OCD responds well, useful in patients with depression w/marked obsessive features. Half life 21 h
Trimipramine
tertiary amine. Highly anticholinergic, very sedating. Half life 22 h
Desipramine
secondary amine. Least anticholinergic, not sedating. Half life 24 h
Nortriptyline
secondary amine less anticholinergic, half life 12 h
Protriptyline
secondary amine less anticholinergic, not sedating. half life 6 h
Amoxapine
tetracyclic. May cause EPS and NMS. (metabolite of loxapine). Less anticholinergic. Half life 30 h
SSRI and SSNRI (side effects)
Agitation, akathisia, anxiety, panic, insomnia, diarrhea, GI distress, headache, sexual dysfunction. To avoid fata serotonin syndrome no SSRI or SSNRI should be combined with a MAOI and an SSRI should be stopped at least 5 weeks before starting an MAOI
Fluoxetine
SSRI. Used in OCD. Half life 1-3 days
Sertraline
SSRI, causes diarrhea more than others. Used in OCD. Half life 25 h
Paroxetine
SSRI. Mildly anticholinergic. Used in treatment of OCD. Half life 24 h
Fluvoxamine
SSRI. Naused and vomiting more common. Used in OCD. Half life 15 h
Citalopram
SSRI. Possibly fewer sexual side effects. Half life 35 h
