Arms and Interventions

Arm	Intervention/treatment
Active Comparator: Ambroxol hydrochloride (BIH1526); One lozenge 20 mg on as-needed basis, up to 6 times per day	Drug: ambroxol BIH1526; Pharmaceutical form: lozenges Route of administration: oromucosal
Placebo Comparator: Placebo; One lozenge on as-needed basis, up to 6 times per day	Drug: placebo; Pharmaceutical form: lozenges Route of administration: oromucosal

Outcome Measures

Primary Outcome Measures :

1. Change in pain intensity difference (PID) [ Time Frame: hour 3 ]
   Change from baseline to hour 3 in time-weighted average of PID after the first lozenge, expressed as the ratio of the predose baseline, sum of PID (SPIDnorm, 0-3h)

Secondary Outcome Measures :

1. Change in SPID [ Time Frame: hour 24 ]
   Change from baseline to hour 24 in time-weighted average of PID after the first lozenge, expressed as the ratio of the predose baseline, sum of PID (SPIDnorm, 0-24h)
2. 3-hour patient assessment of efficacy [ Time Frame: hour 3 ]
   Patient assessment of efficacy after 3 hours of the first study drug intake using a 5-point verbal rating scale (VRS) to rate whether the trial medication relieves sore throat pain, where 0 = poor and 4 = excellent
3. 24-hour patient assessment of efficacy [ Time Frame: hour 24 ]
   Patient assessment of efficacy after 24 hours of the first study drug intake using a 5-point VRS
4. Adverse events [ Time Frame: baseline to day 4 ]
   Incidence of the adverse events
5. Patient assessment of tolerability [ Time Frame: hour 3, hour 24 and day 2, day 3 or day 4 ]
   Patient assessment of tolerability after 3 hours, Day 1, on Day 2, Day 3 and Day 4 using a 5-point VRS, where 0 = poor and 4 = excellent
6. Final assessment of tolerability [ Time Frame: day 4 ]
   Investigator and patient assessment of tolerability on Day 4 using a 5-point VRS, where 0 = poor and 4 = excellent
