ABSTRACT
BACKGROUND AND PURPOSE:
The monoamine oxidase type B inhibitors plus channel blockers (MAO-BIs plus) are a new class of antiparkinsonian drug with additional mechanisms of action for their property as ion channel blockers. The present study aimed to compare the efficacy and safety of MAO-BIs plus and conventional MAO-BIs, as well as their corresponding doses, as adjuvant therapy to levodopa in the treatment of Parkinson's disease (PD).METHOD:
Randomized controlled trials enrolling PD patients treated with selegiline, rasagiline, safinamide or zonisamide as adjuvant therapy to levodopa were identified. Bayesian network meta-analysis was conducted.RESULTS:
Thirty-one randomized controlled trials comprising 7142 PD patients were included. Compared with levodopa monotherapy, the combination therapy of MAO-BIs and levodopa was significantly more effective, with a mean difference of 2.74 (1.26-4.18) on the Unified Parkinson's Disease Rating Scale (UPDRS) III score change for selegiline, 2.67 (1.45-3.87) for safinamide, 2.2 (0.98-3.64) for zonisamide and 2.04 (1.24-2.87) for rasagiline. No significant difference was detected amongst MAO-BIs. The surface under the cumulative ranking results showed that safinamide 100 mg and rasagiline 1 mg ranked first in improving UPDRS III and UPDRS II, respectively. Zonisamide 100 mg ranked first in reducing OFF time. For safety outcomes, rasagiline was associated with a higher incidence of adverse events than placebo and safinamide. MAO-BIs plus had a higher probability of being safer agents compared to conventional MAO-BIs.CONCLUSIONS:
Monoamine oxidase type B inhibitors plus, conventional MAO-BIs and the corresponding doses are similar in efficacy in PD treatment. MAO-BIs plus might be safer than conventional MAO-BIs. Head-to-head comparisons are needed for further investigation.Palavras-chave
