Brief summary

The aim of this trial is to investigate the efficacy and tolerance of Ambroxol lozenges 20 mg in the treatment of sore throat in patients with acute viral pharyngitis.

Detailed description

Male and female ambulant patients complaining of a sore throat caused by acute viral pharyngitis. Every patient may be included in the trial only once. A total of 250 male and female ambulant patients between the ages of 18 and 65 years will be enrolled. Approximately 8 centers will be recruited each enrolling approximately 30-32 patients. Study Hypothesis: The two-sided test hypothesis, that the results of the active treatment group with 20 mg Ambroxol and the placebo group do not differ with regard to the primary endpoint (null hypothesis (H0) will be tested against the alternative (H1) that they are not equal. Comparison(s): PRIMARY ENDPOINT: Indication of pain on the VRS (PI)-verbal rating scale (pain intensity)-in the first 3 hours (the patient rates his/her pain on a six-point verbal rating scale). SECONDARY ENDPOINT (S): 1. Patient's assessment of effectiveness and tolerance. The patient assesses the effectiveness and the tolerance of the test medicine for treating his sore throat at the end of the first and second day of treatment, by means of a verbal rating scale. 2. Participating doctors assessment of tolerance.

Outcome results

Primary

Sum of Pain Intensity Difference (SPIDnorm)-Time-weighted Average of the Pain Intensity Difference (PID) From Pre-dose Baseline Over the First 3 Hours After the First Lozenge Expressed as a Ratio of the Pre-dose Baseline

The calculation will be based on the pain intensity (PI) assessment by the patient before and then at (pain intensity difference at 30 minutes (PID30)), (pain intensity difference at 60 minutes (PID60)), (pain intensity difference at 120 minutes (PID120)) and (pain intensity difference at 180 minutes (PID180)) after the 1st lozenge. Using the difference in PI from pre-dose baseline for each time point subsequent to dosing, the SPIDnorm will be calculated as SPIDnorm = (30\*PID30 + 30\*PID60 + 60\*PID120 + 60\*PID180)/(180\*PI (baseline)) The patient rates the intensity of his sore throat pain on a 6-point Verbal Rating Scale (VRS) pain intensity (PI) before taking the first lozenge and 30, 60, 120 and 180 minutes thereafter, and enters his rating in his patient's diary .
