Lisuride in parkinsonism

Lisuride is a soluble ergolene derivative with endocrine effects similar to but more potent than those of bromocriptine. In nine subjects with idiopathic, postencephalitic, or drug‐induced parkinsonism, lisuride at a dosage of 0.05 to 0.15 mg intravenously caused an immediate improvement in tremor, rigidity, akinesia, and postural deformity, but also caused chorea and orofacial dyskinesia. Improvement lasted 2 to 3 hours. Lisuride had little or no effect in a single patient with progressive supranuclear palsy. Oral lisuride therapy, 0.8 to 4.8 mg daily, had similar effects but occasionally caused reduced awareness and hallucinations.
