Warming Sensation and Tolerability Study of Acetylcysteine 2% Oral Solution for Productive Cough
5 de diciembre de 2016 actualizado por: GlaxoSmithKline
An Open Label Study to Assess the Warming Sensation, Acceptability and Local Oral Tolerability of NCH-GSK Acetylcysteine 2% Oral Solution, Given as a Single Dose in Subjects Suffering From Productive Cough Due to Upper Respiratory Tract Infection
This is a 1-treatment arm, open label design.
This 1-day study includes a screening on day of attendance at clinic, followed by a washout period of 30 minutes to 8 hours (if participants are eligible for dosing the same day).

Medida Descripción |
Periodo de tiempo |
---|---|---|
Onset of Warming Sensation
Periodo de tiempo: 10 minutes post-dose
|
Onset and duration of action of warming sensation was measured by two stop watches started when the participants took the oral solution.
First watch was stopped at the start of warming sensation and the second watch was stopped at the end.
If onset had not occurred by 10 minutes then time to onset was censored at 10 minutes.
53 of the 57 participants had onset within 10 minutes after dosing.

10 minutes post-dose
|
Duration of Warming Sensation
Periodo de tiempo: 10 minutes post-dose
|
Duration of action of warming sensation was measured by two stop watches started when the participants took the oral solution.
First watch was stopped at the start of warming sensation and the second watch was stopped at the end.
If onset of warming sensation occurred within 10 minutes of dosing but had not ended by the end of 10 minutes following dosing, then the duration was censored at 10 minutes minus the time to onset
|
10 minutes post-dose
|
Warming Sensation Intensity at Pre-Dose and 60 Sec (Seconds) Post-Dose
Periodo de tiempo: Pre-dose and 60 sec post-dose
|
Warming Sensation Intensity was measured on 100 mm visual analogue scale (VAS), marked as "no warming sensation" on the left hand side (= 0 mm) and "strongest possible warming sensation" at the right hand side (=100 mm) at pre-dose.

Acceptability of strength of warming sensation was measured by a scale: 5= Much too strong; 4=Too strong (too warming); 3= Just about right (pleasant warming); 2= Too weak (not warming enough); 1= Much too weak
|
10 minutes post-dose
|
Number of Participants With Overall Opinion of Warming Sensation
Periodo de tiempo: 10 minutes post-dose
|
Overall opinion of warming sensation was measured by scale: 9= Like extremely; 8= Like very much; 7= Like moderately; 6= Like slightly; 5= Neither like nor dislike; 4= Dislike slightly; 3= Dislike moderately; 2= Dislike very much; 1= Dislike extremely
|
10 minutes post-dose

|
Overall opinion of oral solution was measured by scale: 4 = Excellent; 3 = Good; 2 = Fair; 1 = Poor; 0 = Unacceptable.
|
1 hour post-dose
|
Local Oral Tolerability
Periodo de tiempo: Day 1 (at screening and end of study)
|
Local oral tolerability was assessed by performing oropharyngeal examination as follows: Results of oropharyngeal examination (Normal and abnormal); If abnormal, any signs of lesion on oral mucosa or irritation of oral mucosa.
