Anti-Depressants and Mood Stabilizers -- Segars Flashcards
TCAs - drugs (2 classes) - 6 total
Despiramine, Nortriptyline, Imipramine, Amitriptyline, Doxepin
Amoxapine
TCAs - MoA
Like what other class?
Block reuptake of NE and 5-HT from synaptic cleft
SNRI’s
***TCAs - side effects
Anti-alpha: tachy, ortho hypotension, dysrhythmias
Anti-muscarinic: dry mouth, urinary retention, blurred vision
Anti-histamine: sedation
TCAs - overdose
3 Cs – coma, cardiotoxicity, convulsions
How does TCA overdose cause cardiotoxicity?
Like what?
Sodium channel blockade (like Quinidine or Class 1A antiarrhythmics) –> slows conduction –> sloped phase 0, prolonged repolarization
SSRIs - drugs (7)
Citalopram Escitalopram Fluoxetine Paroxetine Sertraline Vilazodone Vortioxetine
FLashbacks PARalyze SEnior CITizens
SSRIs - MoA
Selective inhibition of SEROTONIN reuptake by SERT –> enhanced, prolonged serotonin neurotransmission
Why are SSRIs better than TCAs?
MUCH less side effects
Mental status changes, muscle stiffness and hyperreflexia, autonomic instability (sweating, shivering, tremors), hyperthermia
What can cause it?
How to remember?
Serotonin syndrome
ANYTHING that increases serotonin (SSRIs, TCAs, MAOIs)
3 A’s
- Activity of neuromuscular (clonus, hyperreflexia, hypertonia, tremor, seizure)
- Autonomic instability (hyperthermia, diaphoresis, diarrhea)
- Agitation (mental)
CYP450 inhibitor (SSRI)
LEAST inhibition of CYP450 (SSRI)
Fluoxetine
Citalopram/Sertraline
SSRIs - side effects
SNRIs (non-TCAs) - side effects
SARAs - side effects
Serotonin syndrome Sedation Insomnia Weight gain GI distress
SAME
SAME
SNRIs (non-TCAs) - drugs (4)
Venlafaxine/Desvenlafaxine
Duloxetine
Levomilnacipran
SARAs - drugs (3)
MoAs of each
Mirtazapine - block pre-synaptic alpha-2 receptors, 5-HT2 receptors, 5-HT3 receptors, and H1 receptors
Nefazodone, Trazodone - block receptors: 5-HT (SSRI), 5-HT2a, and alpha-1 (post-synaptic)
Specific SARA side effect that may be used purposefully?
Sedation (Mirtazapine) - for insomnia + depression
Bupropion - MoA
Use?
Major side effect?
NDRI – inhibits re-uptake of NE (NET) and dopamine (DAT)
Smoking cessation
Agitation/insomnia (stimulation)
