title: Case report of propranolol (Inderal) pharmacotherapy for neuroleptic-induced akathisia and tremor.
abstract: This case report describes a schizophrenic patient who developed akathisia and tremor following neuroleptic pharmacotherapy with fluphenazine decanoate. The patient also suffered from familial (benign essential) tremor. The patient's neuroleptic-induced extrapyramidal side effects were not relieved by anticholinergic antiparkinson drugs or by phenobarbital. The patient was started on propranolol 10 mg b.i.d. She was also started on diazepam 5 mg t.i.d. for anxiety. The diazepam dose was held constant and propranolol was gradually increased to 40 mg q.i.d. The patient's extrapyramidal symptomatology gradually resolved over the course of one month, during which time the propranolol dose was being steadily increased. Propranolol also effectively controlled her familial tremor. After nine months as an outpatient, during which time the patient was neuroleptic-free, she developed psychotic decompensation for which she was treated with thiothixene. Akathisia or tremor did not develop, possibly because the patient was taking propranolol simultaneously. Propranolol may be useful for treating neuroleptic-induced akathisia. This requires systematic investigation with open and controlled trials.
