RESUMO
OBJECTIVE: To discuss the efficacy of Qingkailing soft capsules in treating acute fever, and the relationship between symptoms-effect and time effect. METHOD: Qingkailing soft capsules was taken orally, 4 times a day, 1.6 g each time.

RESULT: There were 73.34% of patients cured by Qingkailing soft capsules and 43.59% cured by Shuanghuanglian kou fu liquid. The efficacy of the former was better than that of the latter (P < 0.05). The efficacy of Qingkailing soft capsules in treating Fengrexing was better than that in Fenghanxing (P < 0.05). The efficacy of Qingkailing soft capsules in reducing rapid pulse and adding moderate pulse was more remarkable than Shuanghuanglian kou fu liquid (P < 0.05). Taking Qingkailing soft capsules seldom induced mild gastrointestinal disturbance. CONCLUSION: Qingkailing soft capsules showed good result in the treatment of acute upper respiratory tract infection with less adverse effect.
