Mepiprazole

Mepiprazole (Psigodal) is a minor tranquilizer with a phenylpiperazine structure used in Spain for the treatment of anxiety neuroses. It acts as a 5-HT2 and α1-adrenergic receptor antagonist,  and has also been shown to inhibit the reuptake and induce the release of serotonin, dopamine, and norepinephrine to varying extents. Similarly to other phenylpiperazines like trazodone, nefazodone, and etoperidone, mepiprazole produces mCPP as an active metabolite.
