Andrographolide drop-pill in treatment of acute upper respiratory tract infection with external wind-heat syndrome:a multicenter and randomized controlled trial

Objective： To evaluate the safety and efficacy of andrographolide drop-pill in treatment of acute upper respiratory tract infection with external wind-heat syndrome. Methods： A multicenter, randomized controlled trial was conducted. In phase 1, 202 patients with acute upper respiratory tract infection were randomly divided into two groups： trial group （n = 101） and control group （n=101）. In phase Ⅱ, 276 patients with acute upper respiratory tract infection were randomly divided into two groups： trial group （n=138） and control group （n=138）. The patients in the trial group received andrographolide drop-pill, at a dose of 1.5 g, three times a day; the patients in the control group received andrographolide tablet, at a dose of 1.5 g, three times a day. The therapeutic courses in both groups were 3 days. Clinical symptoms, physical signs, adverse effects, blood, urine and stool tests, hepatorenal function and electrocardiogram were examined before and after the treatment. Results, After treatment in the phase I , the cure rates in the trial group and the control group were 44.55%, 42.57% （full analysis set, FAS） and 45.00%, 43.00% （per protocol set, PPS）, and the total obvious rates were 94.06%, 94. 06% （FAS） and 95.00%, 95. 00% （PPS）, respectively. There were no significant differences between the two groups （P〉0. 05）. In the phase Ⅱ, the cure rates in the trial group and the control group were 39.13%, 33.82% （FAS） and 38.69%, 33.58% （PPS）, and the total obvious rates were 96.38%, 96.32% （FAS） and 96.36%, 96.27% （PPS）, respectively. There were no significa＇nt differences between the two groups （P〉0. 05） too. No adverse effects were found in the trial. Conclusion： Andrographolide drop-pill is effective and safe in the treatment of acute upper respiratory tract infection with external wind-heat syndrome.
