title: A double-blind, placebo-controlled, dose-ranging study to investigate the safety and efficacy of CY 208-243 in patients with Parkinson's disease.
abstract: We carried out a double-blind rising dose study of a D-1 dopamine agonist, CY 208-243, in 6 parkinsonian patients. Deficits monitored by Columbia scores were significantly improved at single doses ranging from 5 to 40 mg, though efficacy was low. Used alone, CY 208-243 was not a satisfactory therapeutic agent, and toxicity data precluded further increases in dosage.
