Clinical Trial for Assessment of Safety and Efficacy of a Echinacea/Sage Spray Compared to a Chlorhexidine/Lidocaine Spray in the Treatment of Acute Sore Throats

Multicentric Randomized Double Blind Double Dummy Placebo Controlled Clinical Trial for Assessment of Safety and Efficacy of a Echinacea/Sage Spray in Comparison to a Chlorhexidine/Lidocaine Spray in the Treatment of Acute Sore Throats

The aim of the study is to show non-inferiority of an echinacea/sage spray compared to a chlorhexidine/lidocaine-spray in the treatment of acute sore throat during five days of treatment.

Main outcome parameter is the non-inferiority in number of responders between the two treatment groups. A responder is defined as a reduction by 50% of the total baseline score taken prior to treatment start. The symptoms are assessed with a symptom score.

Further secondary parameters are :

Responders during at day 4 and 5, single symptom scores during 1 to 5 days of observation, pain at begin and end (100mm VAS), assessment of efficacy by physician and patient, consumption of rescue medication

Assessment of safety by physician and patient, frequency of adverse events
