Evaluate the Efficacy and Safety of Andrographolide Sulfonate in Patients With Acute Tonsillitis

Study Overview
=================
Brief Summary
-----------------
A multicenter, randomized, single-blind, placebo-controlled,phase 4 clinical trial to evaluate the efficacy and safety of andrographolide sulfonate in patients with acute tonsillitis

Detailed Description
-----------------
The patient after passing the screening, with the ratio of 1:1, were randomly assigned to experimental group and control group. Experimental group: On the basis of conventional therapy,combined with 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: Xiyanping injection simulation(0.9% normal saline) 10-20ml/d,the treatment method is the same as the experimental group. Treatment cycle: less than 7 days (the longest period of treatment is 7 days, if the clinical symptoms were relieved in the treatment, patients were stoped treatment).
