International guide to drugs for Parkinson's disease.

Pharmacotherapy of Parkinson's disease (PD) has become so effective that patients with PD can enjoy a nearly normal life, including travel for several years. The degree of international travel of patients with PD and in particular the recent increased coordination between health systems in the European community call for a detailed information on the different antiparkinsonian drugs available worldwide. To provide an overview for physicians and patients on the diversity of preparations available in the different countries, we compiled the most commonly used substances along with their size of dosage and formula in an international guide to drugs for PD.
