  • Title: Pramipexole v. levodopa as initial treatment for Parkinson's disease: a randomized clinical-economic trial.
    Author: Noyes K, Dick AW, Holloway RG, Parkinson Study Group.
    Journal: Med Decis Making; 2004; 24(5):472-85. PubMed ID: 15358996.
    Abstract:
    PURPOSE: To determine the 2-year incremental cost effectiveness of initial pramipexole treatment compared with initial levodopa treatment in patients with early Parkinson's disease (PD). METHODS: 301 subjects with early PD were randomized to either pramipexole or levodopa and followed every 3 months over a 2-year period. Costs were assigned to patient collected health utilization data using a variety of methods. Health state preferences were estimated using the EuroQol. RESULTS: Pramipexole strategy was an estimated 2,138 dollars (SE = 1,182 dollars) more expensive than levodopa strategy. The incremental cost-effectiveness of pramipexole compared with levodopa was 106,900 dollars/QALY (EQ-5D), compared with pramipexole being dominated by levodopa using the EQVAS. CONCLUSIONS: Although considerable uncertainty exists in the 2-year cost-effectiveness of initial pramipexole compared with initial levodopa in the treatment of early PD, our estimates suggest that pramipexole may not be welfare enhancing during the first 2 years of treatment. If initial pramipexole results in long-term improvements in quality of life, its cost-effectiveness will become more favorable.
