Detailed Description

The patient after passing the screening, with the ratio of 1:1, were randomly assigned to experimental group or control group. Experimental group: on the basis of Conventional Therapy,Xiyanping injection(andrographolide sulfonate) 10-20ml/d, With 0.9% normal saline 100ml-250ml diluted intravenous drip (not with other drugs in the same container mixed use), control drip speed per minute of 30-40 drops. control group: on the basis of Conventional Therapy,Xiyanping injection simulation(0.9% normal saline) 10-20ml/d, The treatment method is the same as the experimental group.


  • Drug: andrographolide sulfonate
    • Conventional Therapy+Xiyanping injection
  • Drug: andrographolide sulfonate simulation
    • Conventional Therapy+Xiyanping injection simulation

Arms, Groups and Cohorts

  • Active Comparator: Experimental group
    • Conventional Therapy + Xiyanping injection(andrographolide sulfonate)
  • Placebo Comparator: control group
    • Conventional Therapy + Xiyanping injection simulation/andrographolide sulfonate simulation(0.9% normal saline)

Clinical Trial Outcome Measures

Primary Measures

  • cured rate
    • Time Frame: less than 14 days
    • clinical symptoms(fever, cough, expectoration and gasp) and signs totally disappear, the period of lab tests(WBC,CRP, chest X-ray) return to normal is recorded。

Secondary Measures

  • effective time window
    • Time Frame: less than 14 days
    • days range from treatment is received to the effectiveness is observed, and symptoms disappear (fever, cough, expectoration and gasp).
  • days of antibiotic use
    • Time Frame: less than 14 days
    • oral anti infective drugs use days and intravenous anti infective drugs use days are recorded
  • the incidence of complications
    • Time Frame: less than 14 days
    • such as, the incidence of Acute otitis media, acute rhinitis, acute bronchitis, acute bronchitis, and so on.
  • bacterial eradication rate
    • Time Frame: less than 14 days
    • bacterial eradication rate=Sputum culture negative cases after treatment /sputum culture positive cases before treatment x 100% =Sputum culture negative cases after treatment /sputum culture positive cases before treatment x 100%
  • direct medical cost
    • Time Frame: less than 14 days
    • medical cost including hospital expenses, examine fee, medication fee, et al, relate to treatment in hospital
  • number of participants with treatment-related adverse events
    • Time Frame: less than 14 days
    • the total incidence of adverse events, the incidence of adverse events associated with Xiyanping injection, the incidence of patients with grade 3 through grade 4 adverse events that are related to study drug, graded according to NCI-CTC V4.0 . Observe and record all adverse events and serious adverse events, including physical examination, vital signs, laboratory tests (Hematology, blood biochemistry, urine routine, stool routine), ECG changes and so on.
