MAO-B inhibitors, such as selegiline and rasagiline, may be used for early symptomatic treatment of Parkinson disease. These medications provide mild symptomatic benefit, have excellent adverse effect profiles, and may improve long-term outcomes. These characteristics make MAO-B inhibitors a good choice as initial treatment for many patients. When the MAO-B inhibitor alone is not sufficient to provide good control of motor symptoms, another medication (eg, a dopamine agonist or levodopa) can be added.
