Trial Outcomes & Findings for Comparison of Efficacy and Tolerability of Two Cough Syrups in Cough Due to Cold in Children. (NCT NCT01968434)

NCT ID: NCT01968434

Last Updated: 2018-02-23

Results Overview

Night cough is most bothersome to the child and family. Cough was measured with a validated questionnaire which asks parents to rate 5 aspects of night cough: frequency, severity, bothersomeness, child sleep and parent sleep according to a 7 point Likert scale, from 0 (not at all) to 6 (extremely). Lower scores indicate a better condition. The morning after the first night of treatment (N1) the parents rated the passed night by scoring from 0-6 each of the 5 aspects of night cough. The sum of scores for all 5 aspects gives the combined night cough score. This score, ranging between 0-30, was subtracted from the sum of all aspects, also ranging between 0-30, form the basal night cough score of the night before enrollment (N0). This change is recorded as "change in combined night cough score" and it refers to the change from N0 to N1. Negative values of the change indicate an improvement in the condition of the patient.

Protective Cough Syrup
syrup containing honey, plantago lanceolata, grindelia robusta, helichrysum italicum ina syrup form. The cough syrup is a CE marked medical device acting in a non pharmacological way to reduce cough. Dosage: 6,5 ml three times a day for the duration of the study (4 nights, 3 days) protective cough syrup: The mucoadhesive and radical scavenging properties of the components create a protective film on the pharynx which protects irritated mucosa from cough generating stimuli such as post nasal drip, irritating elements, dehydration.

PRIMARY outcome

Timeframe: 1 night from before enrollment (N0) to first night after treatment (N1)

Population: the population analyzed are the children who completed the protocol and submitted the complete questionnaire for night and day cough. 78 patients were enrolled in the protective syrup Group and 72 in the carbocysteine Group. 3 patients in the protective syrup group and 6 in the carbocysteine group never began the study.

Night cough is most bothersome to the child and family. Cough was measured with a validated questionnaire which asks parents to rate 5 aspects of night cough: frequency, severity, bothersomeness, child sleep and parent sleep according to a 7 point Likert scale, from 0 (not at all) to 6 (extremely).

SECONDARY outcome

Timeframe: 4 nights (onset of trial Night 1 to Night 4) and 3 days

Population: 78 patients were enrolled in the protective syrup Group and 72 in the carbocysteine Group. 3 patients in the protective syrup group and 6 in the carbocysteine group never began the study. 7 patients from the protective syrup group and twelve 12 patients from the carbocysteine group did not answer the questions for the last night.

A validated cough questionnaire measuring 5 aspects of night cough (frequency, severity, bothersomeness, child sleep and parents' sleep) on a 7 point Likert scale was used each morning to rate the passed night. The scale rates each parameter from 0 (not at all) to 6 (extremely). Every night of the trial is rated. The morning after the last night of the study (N4) the parents rated the passed night by scoring from 0-6 each of the 5 aspects of night cough. The summed score for all aspects gives the combined night cough score. This score, ranging between 0-30, was subtracted from the sum of all aspects, also ranging between 0-30, form the basal night cough score of the night before enrollment (N0). This change is recorded as "change in combined night cough score" and it refers to the change from N0 to N4. Negative values of the change indicate an improvement in the condition of the patient.

SECONDARY outcome

Timeframe: 4 nights (onset of trial Night 1 to Night 4) and 3 days

Population: 78 patients were enrolled in the protective syrup Group and 72 in the carbocysteine Group. 3 patients in the protective syrup group and 6 in the carbocysteine group never began the study. 6 patients from the protective syrup group and twelve 11 patients from the carbocysteine group did not answer the questions for the last day.

A validated cough questionnaire measuring 3 aspects of daytime cough (frequency, severity, bothersomeness) on a 7 point Likert scale was used each evening to rate the passed day, as regards these aspects. The scale rates each parameter from 0 (not at all) to 6 (extremely). Every day of the trial is rated. The last evening of the study (D4) the parents rated the passed day by scoring from 0-6 each of the 3 aspects of day cough. The summed score for all aspects gives the combined day cough score. This score, ranging between 0-18, was subtracted from the sum of all aspects, also ranging between 0-18, form the basal day cough score of the day before enrollment (D0). This change is recorded as "change in combined day cough score" and it refers to the change from D0 to D4. Negative values of the change indicate an improvement in the condition of the patient.
