Atypical antidepressant
An atypical antidepressant is any antidepressant medication that acts in an manner that is different from that of most other antidepressants. Atypical antidepressants include agomelatine, bupropion, mianserin, mirtazapine, nefazodone, opipramol, tianeptine, and trazodone.[1][2][3] The agents vilazodone and vortioxetine are partly atypical. Typical antidepressants include the SSRIs, SNRIs, TCAs, and MAOIs, which act mainly by increasing the levels of the monoamine neurotransmitters serotonin and/or norepinephrine.[1][2][3] Among TCAs, trimipramine is an atypical agent in that it appears not to do this.[3]
Esketamine (JNJ-54135419) and buprenorphine/samidorphan (ALKS-5461) are antidepressants with novel mechanisms of action which are under development and are considered atypical antidepressants.[4] They act faster than available antidepressants.[4]
