We report a case of fulminant neuroleptic malignant syndrome in a man aged 70 developing within 12 hours of starting six-hourly intravenous metoclopramide. The muscle rigidity and hyperpyrexia were unresponsive to intravenous benztropine but resolved within one hour of intravenous dantrolene 2 mg/kg. Within six hours the patient had a partial relapse which resolved completely following further intravenous dantrolene 2 mg/kg. This case demonstrates that the rapid effect of intravenous dantrolene can be life saving in fulminant neuroleptic malignant syndrome.

D009459 Neuroleptic Malignant Syndrome A potentially fatal syndrome associated primarily with the use of neuroleptic agents (see ANTIPSYCHOTIC AGENTS) which are in turn associated with dopaminergic receptor blockade (see RECEPTORS, DOPAMINE) in the BASAL GANGLIA and HYPOTHALAMUS, and sympathetic dysregulation. Clinical features include diffuse MUSCLE RIGIDITY; TREMOR; high FEVER; diaphoresis; labile blood pressure; cognitive dysfunction; and autonomic disturbances. Serum CPK level elevation and a leukocytosis may also be present.

D003620 Dantrolene Skeletal muscle relaxant that acts by interfering with excitation-contraction coupling in the muscle fiber. It is used in spasticity and other neuromuscular abnormalities. Although the mechanism of action is probably not central, dantrolene is usually grouped with the central muscle relaxants. Dantrium,Dantrolene Sodium,Sodium, Dantrolene
