Przuntek H, Bittkau S, Bliesath H, et al. Budipine Provides Additional Benefit in Patients With Parkinson Disease Receiving a Stable Optimum Dopaminergic Drug Regimen. Arch Neurol. 2002;59(5):803–806. doi:10.1001/archneur.59.5.803
The complex pharmacological profile of the antiparkinsonian drug budipine influences neurotransmission beyond the dopaminergic system. Previous studies have demonstrated the therapeutic efficacy of budipine on motor symptoms in insufficiently treated patients with Parkinson disease.
To demonstrate the efficacy of 20 mg of budipine, 3 times daily, in addition to a stable, prior, optimum-titrated dopaminergic substitution consisting of a combination of levodopa and a dopa decarboxylase inhibitor, bromocriptine mesylate, and optional selegiline hydrochloride in 99 patients with idiopathic Parkinson disease in a multicenter, double-blind, placebo-controlled trial.
Budipine significantly (P<.001) decreased the Columbia University Rating Scale sum score (median, 15.0; 95% confidence interval, 11.3-17.0) compared with placebo (median, 4.3; 95% confidence interval, 3.0-7.5) at study end point. Budipine reduced Columbia University Rating Scale subscores for tremor, rigidity, and akinesia.
The additional application of budipine provides further therapeutic benefit in subjects with Parkinson disease receiving a stable, prior, optimum-titrated dopaminergic drug regimen because of the hypothetical positive impact of budipine on altered nondopaminergic neurotransmission in patients with Parkinson disease.
