-Dual-action antidepressants, similar to TCAs
-Highly selective for NT and 5-HT
-Analgesic; can relieve pain
What is nefazodone?

What is mirtazepine?
-Mirtazepine is a tetracyclic
-It’s brand name is Remeron
-It has a half life of 10-20 hours

What is maprotiline?
-Maprotiline is a second generation antidepressant that is a modified TCA

What is amozapine?
-Amozapine is a second generation antidepressant who is a NET antagonist
-It’s brand name is Ascendin

-Trazodone is a second generation antidepressant
-It’s brand name is Desyrel
-Trazodone is a weak NET, SERT antagonist and blocks 5-HT2A
