Rasagiline

Indications

Rasagiline is indicated for the treatment of the signs and symptoms of idiopathic Parkinson's disease as initial monotherapy, and as adjunct therapy to dopamine agonists or to levodopa.

Pharmacology

Rasagiline is a potent, irreversible, selective MAO-B inhibitor that effectively crosses the blood brain barrier after oral administration. The precise mechanisms of action of Rasagiline are unknown. One mechanism is believed to be related to its MAO-B inhibitory activity, which causes an increase in extracellular levels of dopamine in the brain. The elevated dopamine level and subsequent increased dopaminergic activity are likely to mediate Rasagiline's beneficial effects.
