Sumario:BACKGROUND: We aimed to compare indicators of Parkinson disease (PD) progression between patients first prescribed either selegiline or rasagiline as their antiparkinsonian drugs (APDs) on the basis of real-life data. METHODS: Pharmacy data on members of a large Israeli health maintenance organization, treated as patients with PD during 2001–2012 and prescribed selegiline or rasagiline as their first APD, were analyzed. The first APD was selegiline for 349 patients (2001–2006) and rasagiline for 485 patients (2007–2012). Time from monoamine oxidase type B inhibitor prescription until initiating treatment with dopamine agonists (DAs) or levodopa was compared between the groups using Cox regression adjusted to sex and age at initiation of APD. RESULTS: The selegiline group was significantly older at first monoamine oxidase type B inhibitor purchase. In a similar follow-up time (3.0 [1.7] year for selegiline group, 3.1 y [1.4] for rasagiline group), the time to initiation of levodopa treatment did not differ between the 2 groups (adjusted hazard ratio [HR], 1.06; 95% confidence interval [CI], 0.86–1.31). The time to initiation of DA treatment was longer in the selegiline group (adjusted HR, 1.93; 95% CI, 1.49–2.53). For those who were treated with DA before levodopa (n = 276), the time to initiation of levodopa treatment was longer in the rasagiline group (adjusted HR, 0.77; 95% CI, 0.56–1.07). CONCLUSIONS: The similarity in time to levodopa in both groups suggests no differences between selegiline and rasagiline in their effect on the natural history of PD. A possible interaction effect between rasagiline and DA might exist. A better symptomatic profile of selegiline more than that of rasagiline in the earlier stages of PD may explain the difference between the 2 groups in time to DA initiation.
