Fluperlapine (NB 106-689), also known as fluoroperlapine, is a morphanthridine (11H-dibenzo[b,e]azepine ) atypical antipsychotic with additional antidepressant and sedative effects. It was first synthesized in 1979, and then subsequently studied in animals and humans in 1984 and beyond,[1] but despite demonstrating efficacy in the treatment of a variety of medical conditions including schizophrenia,[2][3][4][5] psychosis associated with Parkinson's disease,[6] depressive symptoms, and dystonia,[7] it was never marketed.[1] This was perhaps due to its capacity for producing potentially life-threatening agranulocytosis, similarly to clozapine,[8] which it closely resembles both structurally and pharmacologically.
