RESUMO
Objective To study the efficacy of entacapone for motor fluctuations in Parkinson's disease. Methods Pubmed, Embase, Cochrane Database were searched for randomized controlled trial studies (RCTs) on entacapone compared to placebo in the treatment of Parkinson' s disease with motor fluctuations. Data were extracted and evaluated by two reviewers independently with designed extractian form. Revman 4. 2. 10 software was used for data analysis. Results Ten RCTs involving 2212 patients were included. The Results showed that entaeapone tends to increase "on" time, decrease "off" time and daily levodopa dosage (WMD=-1.41,95% CI -2. 09- -0.72) and improve "on" time motor symptoms and the quality of life. But it might increase the rate of dyskinesia (OR=2.00, 95% CI 1.55-2.58).Conclusion The systematic review indicates that entaeapone might be an effective agent for parkinsonian patients with motor fluctuations and more high quality RCTs with the same effect measures are required.
