Abstract:
OBJECTIVE To evaluate the safety and efficacy of piribedil combined with levodopa in the treatment of Parkinson's disease (PD).
METHODS Randomized controlled trials of piribedil combined with levodopa for PD were gathered from Cochrane Library, PubMed, Science Direct, CNKI, WanFang and VIP from their establishment to September 2015. Two reviewers independently screened the studies, extracted the data and assessed the quality according to the inclusion and exclusion criteria. The Meta-analysis was conducted with RevMan 5.3 software.
RESULTS A total of 9 randomized controlled trials (RCTs) involving 697 PD patients were included. The results of Meta-analysis showed that compare with placebo plus levodopa or levodopa, piribedil plus levodopa significantly greater improvements in total unified Parkinson's disease rating scale (UPDRS) scores, motor UPDRS scores and activities of daily living UPDRS scores in participants with PD with statistically differencesTotal UPDRS scores:MD=-9.20, 95%CI(-11.28,-7.12),
P<0.000 01; Motor UPDRS scores:Follow-up time was less than or equal to 6 months, MD=-3.04, 95%CI(-4.92, -1.16),
P=0.002; Follow-up time was more than 6 months, MD=-10.81, 95%CI(-14.76, -6.86),
P<0.000 01; activities of daily living UPDRS scores:MD=-1.28, 95%CI(-2.31, -0.26),
P=0.01, and more gastrointestinal adverse events incidences with statistically differencesOR=1.86, 95%CI(1.04, 3.31),
P=0.04.
CONCLUSION Piribedil in addition to levodopa is an effective combination therapy for PD, and significantly improvements in total UPDRS scores, motor UPDRS scores and activities of daily living UPDRS scores, and we should more focus on the gastrointestinal adverse events too.
