Antidepressants / Bipolar drugs Flashcards

1

Q

MOA/Neurochemical Effects: Blocks reuptake of 5HT from synapse (5HT2A R)  can trigger actions postsynaptically or bind to autoreceptors & inhibit more 5HT release

A

Selective Serotonin Reuptake Inhibitors
Fluoxetine (Prozac),

Q

MOA/Neurochemical Effects: SNRI – blocks 5HT + NE reuptake

Efficacy improves with increasing dose (increase dose: only 5HTalso NEalso DA)
