Acute treatment of Huntington's chorea with lisuride.
The authors studied the effects of lisuride hydrogen maleate (lisuride) on the hyperkinesias of 11 patients suffering from Huntington's chorea (HC). In all patients, acute injection of 150 micrograms of the drug induced a marked temporary improvement of the abnormal involuntary movements; the favourable drug-effect was more pronounced in the patients with a less severe degree of hyperkinesia. The antichoreic activity of the drug was prevented by pretreatment with haloperidol (2 mg) or sulpiride (400 mg), both injected intramuscularly 30 min before lisuride administration. The authors suggest the improvement of the motor disturbance induced in HC by lisuride may be explained on the basis of its preferential action on a subset of brain dopaminergic receptor.
