Abstract | BACKGROUND: METHODS: Several databases were adopted in February 5th 2016, so as to identify relevant randomized controlled trial (RCT). Studies indicated that the patients in the experimental group had to receive roflumilast and concomitant treatment with long-acting bronchodilators, and the patients in the control group had to receive placebo and concomitant treatment with long-acting bronchodilators. The primary outcome was COPD exacerbations and the secondary outcome was adverse events. The relative risks (RRs) and 95% confidence intervals (CIs) were calculated. RESULTS: Total 5,746 patients were involved in all six trials. Roflumilast combined with long-acting bronchodilators could lead to significant reduction in exacerbations of COPD (RR, 0.77; 95% CI, 0.69 to 0.86; P<0.00001; I2=0%), and cause some adverse events such as: back pains, headache, diarrhea, nausea, weight loss, insomnia and decreased appetite. According to the subgroup analysis, the test for finding subgroup difference between roflumilast combined with long-acting bronchodilators and roflumilast combined with ICS and long-acting bronchodilators showed no significance in reducing exacerbations. CONCLUSIONS:
Roflumilast combined with long-acting bronchodilators is a better option for moderate-to-severe COPD patients than exclusive use of long-acting bronchodilators in reducing exacerbations. However, it can cause some side effects. Further study needs consider well enough of the benefits and adverse events caused by roflumilast combined with long-acting bronchodilators.
