[A double-blind, randomized controlled trial of Chaige Qingre Granule in treating acute upper respiratory tract infection of wind heat syndrome].
OBJECTIVE
To evaluate the safety and efficacy of Chaige Qingre Granule, a traditional Chinese compound herbal medicine, in treating acute upper respiratory tract infection of wind heat syndrome.


METHODS
A multi-center, double-blinded, randomized controlled trial was conducted. In the phase II, 60 patients with acute upper respiratory tract infection were randomly divided into the trial group (n=30) and the control group (n=30). In the phase III, 112 patients were randomly divided into the trial group (n=84) and the control group (n=28). The trial group received 6 g Chaige Qingre Granule, and the control group received 6 g Fufang Shuanghua Granule (another traditional Chinese compound herbal medicine). The two groups were all treated for 3 days and four times daily. Clinical symptoms, syndromes, adverse effect, blood, urine and stool test, hepatorenal function and electrocardiogram were examined before and after the treatment.


RESULTS
After treatment, the overall obvious response rates of the trial group and the control group were 78.57%, 82.14% (by per-protocol analysis) and 75.86%, 79.31% (by intention-to-treat analysis) respectively, and the overall response rates of the two groups were 96.43%, 100% (by per-protocol analysis) and 93.10%, 96.55% (by intention-to-treat analysis) respectively in phase II. There were no significant differences between the two groups (P>0.05). In the phase III, the overall obvious response rates of the trial group and the control group were 90.54%, 73.08% (by per-protocol analysis) and 88.16%, 70.37% (by intention-to-treat analysis) respectively, and the overall response rates of the two groups were 94.59%, 96.15% (by per-protocol analysis) and 92.11%, 92.59% (by intention-to-treat analysis) respectively. There were no statistical differences between the two groups (P>0.05) too. No adverse effects were found in the trial.


CONCLUSIONS
Chaige Qingre Granule is effective and safe in treating acute upper respiratory tract infection of wind heat syndrome.
