title: Low dosages of bromocriptine added to levodopa in Parkinson's disease.
abstract: Thirty-six patients with Parkinson's disease, on levodopa, were admitted to a double-blind, parallel, 40-week study of adjunct bromocriptine in dosages increased by 2.5 mg every 4 weeks. A 37% improvement of the mean neurologic deficit score was obtained at the maximal daily dosage of 20 mg. Improvement was greatest in patients with mild disease. The wearing-off effect, off-dose abnormal involuntary movements, and leg pains, associated with levodopa, improved in over 70% of patients at an average dosage of 13 mg. Only 15% of patients had adverse reactions severe enough to necessitate discontinuance of the drug. Abnormalities of mental state were less severe than expected, but two patients had exacerbations of angina pectoris.
