METHODS OF TREATING PATIENTS SUFFERING FROM MOVEMENT DISORDERS

摘要

The present invention is directed to methods of treating movement disorders by administering an effective amount of one or more adenosine A2A receptor antagonist to a patient in need thereof. The present invention also provides methods of decreasing the adverse effects of L-DOPA in patients receiving L- DOPA therapy in the treatment of Parkinson~s disease. The present invention further provides methods and compositions for treating Parkinson~s disease patients with sub-clinically effective doses of L-DOPA by combining LDOPA treatment with an effective amount of one or more adenosine A2A receptor antagonists (i.e., L-DOPA sparing effect). The present invention further provides methods of effective treatment of Parkinson~s disease by co- administering at least one adenosine A2A receptor antagonist, L-DOPA and a dopamine agonist and/or a COMT inhibitor and/or a MAO inhibitor. The present invention further provides methods of prolonging effective treatment of Parkinson~s disease by administering an adenosine A2A receptor antagonist singly or together with a dopamine agonist, and/or a COMT inhibitor, and/or a MAO inhibitor without prior or subsequent administration of L-DOPA, delaying or removing on-set of L-DOPA motor complication.
