Randomized Controlled Trial Multicenter Study
Effects of Yangxue Qingnao Granules on chronic cerebral circulation insufficiency: a randomized, double-blind, double-dummy, controlled multicentre trial.
There is a great deal of interest in traditional Chinese medicine as a treatment for chronic cerebral circulation insufficiency (CCCI). In the present study, we evaluated the efficacy and safety of Yangxue Qingnao Granules (YXQNG) as a monotherapy in patients with CCCI. ⋯ These data demonstrate that YXQNG as a monotherapy were as effective as nimodipine monotherapy in improving the symptoms of CCCI. It is well-tolerated and may have an important place in the management of this condition. Whether a combination of these two medicines will increase therapeutic efficacy deserves further clinical investigation.
