title: Fluperlapine in tardive dyskinesia and parkinsonism.
abstract: Fluperlapine, a new clozapine-like neuroleptic drug with weak affinity for dopamine receptors, was evaluated in a blind, placebo controlled trial in 11 patients with stable hyperkinesia (ten with tardive dyskinesia (TD) and one with spontaneous dyskinesia). Drug effects during active treatment (200-600 mg/day) and during pre- and post-treatment placebo periods were determined by scoring randomly sequenced videotapes of TD and parkinsonian symptoms recorded weekly during standardized examinations. TD score was unchanged, while parkinsonism slightly decreased (P less than 0.05) and eye-blinking rates increased (P less than 0.05). Psychiatric symptoms showed no significant changes, although positive psychotic symptoms diminished in four patients. Side effects included dizziness, sedation and constipation. The effects in movement disorders found in this study may imply that fluperlapine is less liable than traditional neuroleptics to induce acute extrapyramidal side effects and tardive dyskinesia and is particularly beneficial in the treatment of patients vulnerable to neurological side-effects.
