NCT00707902

Brief Summary

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.

Outcome Measures

Primary Outcomes (1)

  • comparison of responder of the two treatment groups after the first, second, and third days. A responder is defined as a reduction by 50% of the total baseline score taken prior to treatment start.

    first three days of treatment

Secondary Outcomes (1)

  • Comparison of response rates after 4th and 5th days of treatment; VAS throat pain; amount rescue medication used; global assessment efficacy Frequency of adverse events, global assessment of tolerability

    five days of treatment

Study Arms (2)

2

ACTIVE COMPARATOR

Drug: Echinacea/sage patients received additionally a placebo-spray for the synthetical comparator (chlorhexidine/lidocaine) as the study was double dummy blinded. Patients had to apply spray every 2 hours with two puffs to the pharyngeal area up to a maximum of 10 times daily. Treatment duration was until illness was resolved or for a maximum of 5 consecutive days. Arms: 1

Drug: echinacea/sage
