FOR THE INITIAL AND LONG-TERM TREATMENT OF PARKINSON'S DISEASE (PD)
MIRAPEX helps you reserve the use of levodopa until patients need it most1,14
At 4 years, MIRAPEX patients needed 38% less levodopa than patients taking levodopa alone1
The Parkinson Study Group. JAMA, 2000; Archives of Neurology, 2004.
Multicenter, parallel-group, double-blind, randomized, controlled trial in 301 patients with early PD (Hoehn and Yahr stages I-III).
Objective: to compare initial treatment with MIRAPEX vs levodopa with respect to the development of dopaminergic motor complications. Dosing:
(2 year): subjects were escalated initially to a daily dose of MIRAPEX 1.5 mg or levodopa 75/300 mg; (4 year): the maintenance dose of MIRAPEX was maintained throughout the trial; supplemental levodopa was permitted if needed. Patients were titrated to a maximum dose of MIRAPEX 4.5 mg or levodopa 600 mg. Primary outcome variables were time to the first occurrence of dopaminergic complications: wearing-off, dyskinesia, or "on"-"off " fluctuations. Secondary outcome variables included changes in UPDRS (Unified Parkinson's Disease Rating Scale) scores.
Conclusion: initial treatment with MIRAPEX resulted in fewer incidences of dyskinesia and wearing-off compared with levodopa.
- Patients taking MIRAPEX (average of 2.78 ± 1.1 mg/day) took an average of 268 mg less levodopa per day
Initiating therapy with a dopamine agonist can provide long-term treatment benefits
- Dopamine agonists reduce the risk of motor complications vs levodopa14
- Dopamine agonist monotherapy provides antiparkinsonian efficacy in early Parkinson's disease4,14-17
- Patients with Parkinson's disease may be maintained on dopamine agonist monotherapy for several years15
- As Parkinson's disease advances, supplemental levodopa provides clinical benefits14,15,18
The use of dopamine agonists to delay and reduce the quantity of levodopa administration has the potential advantages of :19
- Reducing the incidence of levodopa-related motor complications
- Avoiding the priming effect of levodopa
- Reducing the cumulative exposure to levodopa
