Budipine in Parkinson's tremor.
It is generally accepted that patients with a tremor-dominant type of idiopathic Parkinson's disease progress more slowly than the ones with the rigid-akinetic type. On the other hand successful treatment of Parkinsonian tremor is a challenge. German neurologists use anticholinergics, budipine, beta-blockers, clozapine, dopaminergic substances and for most severe cases deep brain stimulation. Budipine is an enigma because its main mode of action is still unknown, although it is mostly listed under glutamate antagonists. There is however no other anti-Parkinsonian drug available with such a broad spectrum of action as shown for budipine. Budipine has been studied in open and double-blind studies as monotherapy and adjunct therapy. In both instances the drug showed beneficial effects to the patients. It may well be that the non-dopaminergic mode of action of budipine is helpful even for patients who are on stable medication. When 3 years ago reports on budipine-induced prolongation of the QT interval in the ECG emerged larger trials were stopped and nowadays there are strict rules on how to use budipine. Nonetheless, budipine in our hands is a most useful and safe drug to treat tremor and other main symptoms of Parkinson's disease.
