Safety and Efficacy of the Sore Throat Lozenges to Treat Acute Sore Throats

Assessment of safety after acute intake of 90 minutes at visit 1 and after 4 days of continous intake at final visit 2 by physician with very good, good, moderate, bad

Change of acute throat pain (pain reduction) on a visual analog scale (VAS) ranging from 0 millimeters (no pain) to 100 millimeters (most severe pain) within 90 minutes compared to baseline

Rate and number of Treatment responders expressed on a Tonsillopharyngitis Score (TSS) measuring change of sore throat symptoms at day 1,2,3,4 (Responder=TSS reduction by 50% compared to baseline). The TSS score consists the following four symptoms: throat pain, difficulty in swallowing, salivation, reddening and fever (fever was defined as >38.5°C for this score) which are all rated on a scale with 0=none, 1=mild, 2=moderate, 3=severe.

Change of Tonsillopharyngitis Score (TSS) total at the end of treatment at day 4 as compared to baseline measurement. The TSS score consists the following four symptoms: throat pain, difficulty in swallowing, salivation, reddening and fever (fever was defined as >38.5°C for this score) which are all rated on a scale with 0=none, 1=mild, 2=moderate, 3=severe.

Change of acute throat pain (pain reduction) on a visual analog scale (VAS) ranging from 0 millimeters (no pain) to 100 millimeters (most severe pain) on the evenings of day 1,2,3,4 compared to baseline

Absolute and relative distribution of the single symptoms: throat pain, difficulty in swallowing, salivation, reddening and fever (fever was defined as >38.5°C for this score) from the Tonsillopharyngitis Score (TSS) on day 1,2,3,4 compared to baseline

The relative number of painfree patients that experience a change of acute throat pain (pain reduction) on a visual analog scale (VAS) ranging from 0 millimeters (no pain) to 100 millimeters (most severe pain) of lower than 10 (<10) at day 1,2,3,4 compared to baseline

The time taken to symptom resolution reaching a Tonsillopharyngitis Score (TSS) of less than 3 (<3). The TSS score consists the following four symptoms: throat pain, difficulty in swallowing, salivation, reddening and fever (fever was defined as >38.5°C for this score) which are all rated on a scale with 0=none, 1=mild, 2=moderate, 3=severe.

The average time required for subjective symptom resolution

The rate of use and kind of concomitant medication that are used by patients are recorded by questionaire as part of the patient diary and analyzed in descriptive manner

Throat status (reddening, swelling, inflammation) assessed by physician. Assessed are: The presence of reddening in the throat (yes/no) and swelling (light, moderate, severe) and reddening, swelling, and coating of the tonsils (yes/no). beginning vs. after 90 minutes of treatment vs. 4 days of treatment.

Global subjective assessment of the subjective efficacy after acute intake of 90 minutes at visit 1 and after 4 days of continous intake at final visit 2 rated 1) by physician and 2) by the patient with "very good", "good", "moderate", "bad"

The rate of treatment acceptance assessed by asking patients if they would retake the IMP (yes) or refuse (no) at final visit 2.

The rate and kind of occuring adverse events assessed at visit 2 and analyzed in descriptive manner

Global subjective assessment of the subjective tolerability after acute intake of 90 minutes at visit 1 and after 4 days of continous intake at final visit 2 rated by the patient with "very good", "good", "moderate", "bad"

Rate and kind of clinically relevant changes in vital parameters (pulse, both blood pressure, body temperature) derived from exhamination by investigating physician at inclusion visit 1 and at final visit 2

Rate and kind of clinically relevant changes in blood parameters measured from haematological and biochemical analysis of blood samples analyses as asssessed by the investigating physician. Laboratory blood values that are measured: ALAT, ASAT, total bilirubin, plasma glucose, serum creatinine, ESR (1h), CRP, total cholesterol, erythrocytes, MCHC, MCH, MCV, hematocrit, hemoglobin, leukocytes, and thrombocytes] derived from clinical laboratory analyses and assessed by investigating physician at visit 1 and compared to measurements at final visit 2
