Antidepressants Quick Deck Flashcards
Block reuptake of NE and/or 5HT
Desipramine = NE-selective
Imipramine = NE and 5HT
Higher concentration of NT at their receptors
Tricyclic Antidepressants
Desipramine (Norpramin)
Imipramine (Tofranil)
Irreversibly blocks MAO-A (NE and 5HT) and MAO-B (DA)
Increased NT in vesicles/released/action at R
Monoamine Oxidase Inhibitors
Phenelzine (Nardil)
Blocks reuptake of 5HT from synapse (5HT2A R) can trigger actions postsynaptically or bind to autoreceptors & inhibit more 5HT release
Selective Serotonin Reuptake Inhibitors
Fluoxetine (Prozac),
Sertraline (Zoloft), Escitalopram (Lexapro)
SNRI – blocks 5HT + NE reuptake
Efficacy improves with increasing dose (increase dose: only 5HTalso NEalso DA)
Venlafaxine (Effexor)
Blocks presynaptic α2 R on NE neurons (autoR) and 5HT neurons (heteroR) increases NE and 5HT levels
Mirtazapine (Remeron)
Injectable anesthetic, NMDA antagonist (glutamate)
Ketamine
Effects postsynaptic neuron – alters gene expression implicated in long-term neuroplastic events long-term mood stabilization
Lithium Carbonate
Lithobid, Eskalith
