BACKGROUND:Cognitive and behavioral adverse events (AEs) such as hallucinations, confusion, depression, somnolence and other sleep disorders commonly limit effective management of motor symptoms in PD. Rasagiline (N-propargyl-1(R)-aminoindan) mesylate is a novel, second-generation, selective, irreversible monoamine oxidase type B inhibitor, demonstrated in monotherapy and adjunctive trials to be effective for PD with excellent tolerability. METHODS: The occurrence of cognitive and behavioral AEs and the change from baseline in the Unified Parkinson's Disease Rating Scale (UPDRS) part I mental subscores were reviewed in two multicenter, randomized, placebo-controlled, 26-week trials of rasagilinefor early and moderate-to-advanced patients with PD. The UPDRS is a multi-item rating scale specific to PD; part I rates the patient's intellectual impairment, thought disorders, depression and motivation/initiative. RESULTS: The TEMPO study evaluated rasagiline monotherapy in early PD patients (n=404). The PRESTO study evaluated rasagiline as adjunctive therapy in moderate-to-advanced PD patients with motor complications who were receiving optimizedlevodopa/carbidopa (n=472). In the analysis of adverse event reporting for both studies, no cognitive and behavioral AE in either the rasagiline 1 mg or placebo groups exceeded 10% of the study population and the frequency differences between rasagiline 1 mg and placebo never exceeded 3%. There was no adverse effect on the UPDRS mental subscore relative to placebo in either of the two studies. CONCLUSION:Rasagiline 1 mg once daily improves PD symptoms and motor fluctuations in early and moderate-to-advanced PD patients without causing significant cognitive and behavioral AE or adverse changes in mentation, behavior and mood.
