Trial Review

Please note the ANZCTR will be unattended from Friday 20 December 2024 for the holidays. The Registry will re-open on Tuesday 7 January 2025. Submissions and updates will not be processed during that time.

Registering a new trial?

To achieve prospective registration, we recommend submitting your trial for registration at the same time as ethics submission.

The safety and scientific validity of this study is the responsibility of the study sponsor and investigators. Listing a study does not mean it has been endorsed by the ANZCTR. Before participating in a study, talk to your health care provider and refer to this information for consumers

Intervention/exposure
Study type
Interventional
Description of intervention(s) / exposure
The study aims at comparing 2 methods of bronchodilator challenge in patients with asthma or COPD.
The patients will be challenged with Salbutamol 200-800 mcg via metered dose inhaler (MDI) and spacer (intervention). During the latter part each patient will receive an incremental dose of Salbutamol MDI and spacer starting from 200mcg and increasing by further 200mcg each time, up to 800mcg in total. The patients will have spirometry after each dose which will be given 5-10 minutes apart. Airway reversibility will be measured during spirometry and side effects monitored.
The patients are tested on 2 separate days spending approximately one hour each time. They will be asked to come back within the same week starting from the following day, at approximately the same time of day to control for diurnal variation in respiratory function.

Diagnosis / Prognosis
Comparator / control treatment
The patients will be challenged with Salbutamol 5mg nebules (control). During the latter part each patient will receive an incremental dose of Salbutamol MDI and spacer starting from 200mcg and increasing by further 200mcg each time, up to 800mcg in total. The patients will have spirometry after each dose which will be given 5-10 minutes apart. Airway reversibility will be measured during spirometry and side effects monitored.

Outcomes
Primary outcome [1] 2448 0
Compare the measured airway reversibility between the two methods of bronchodilator delivery.
Timepoint [1] 2448 0
Measured after each intervention. When the patients receive the MDI and spacer, with each dose increment (as above), spirometry will be measured.
Secondary outcome [1] 4213 0
1- Establish the equivalent dose of Salbutamol given via MDI and spacer to that of a nebuliser.
Timepoint [1] 4213 0
This analysis will be performed at the end of the trial after collecting all data.
Secondary outcome [2] 4214 0
2- Compare the safety of both methods of delivery.
Timepoint [2] 4214 0
Secondary outcome [3] 4215 0
Side effects such as tachycardia, tremor, sweatiness, respiratory distress or any other discomfort reported by the patient will be monitored immediately after each intervention and in the MDI group after each dose. A routine measurement will be the pulse rate following each dose.
Timepoint [3] 4215 0
