Alpha methyldopahydrazine as an adjunct to levodopa therapy in Parkinson's disease.

A double-blind, double-observer study was carried out in twenty-five patients with Parkinson's disease. Alpha methyldopahydrazine in combination with L-dopa was compared to placebo with L-dopa. Combination therapy resulted in a reduction in L-dopa dosage to 1/3 of the amount required during the baseline. There were no side effects attributed directly to the alpha methyldopahydrazine. The overall incidence of side effects in the two groups was similar but the combination therapy significantly reduced the incidence of nausea and vomiting. The limiting factor in the combination therapy was the presence of L-dopa induced dyskinesias.
