title: Treatment of parkinson's disease with bromocriptine.
abstract: Bromocriptine in high doses (up to 100 mg per day) was administered to 14 patients with advanced Parkinson's disease whose disorder was progressing despite optimum treatment with levodopa combined with a peripheral dopa decarboxylase inhibitor (carbidopa). In 10, bromocriptine (mean dose, 57 mg) induced a statistically significant (P less than 0.01) improvement in rigidity, tremor, bradykinesia, gait disturbance and total score. In seven patients levodopa with carbidopa was completely replaced by bromocriptine (mean dose, 70 mg), with improvement in four. Adverse effects were similar to those observed with levodopa and carbidopa, except that in individual patients abnormal involuntary movements and diurnal oscillations in performance (on-off effect) were decreased whereas orthostatic hypotension and mental changes were increased. Bromocriptine appears to be a major new agent in Parkinson's disease that is especially promising in patients no longer responding to levodopa.
