| Scientific title | Assessment of changes in ventilation following induced bronchoconstriction with inhaled histamine in normal subjects using Krypton-81m ventilation scintigraphy |
| Study objectives | The aim is to increase the understanding and develop quantitative measures of regional airway function using ventilation scanning using Krypton-81m. |
| Ethics approval(s) | Not provided at time of registration |
| Health condition(s) or problem(s) studied | Respiratory |
| Intervention | Single blind randomised controlled trial. The protocol compares histamine (to induce bronchoconstriction) with normal saline (as control) i.e. no bronchoconstriction. |
| Intervention type | Drug |
| Pharmaceutical study type(s) | |
| Phase | Not Applicable |
| Drug / device / biological / vaccine name(s) | Histamine |
| Primary outcome measure | 1. To determine if ventilation scintigraphy can be used to determine and quantify regional changes in ventilation in the lung following histamine challenge in normal subjects 2. Also to determine the extent to which these correlate with changes in overall lung function |
| Secondary outcome measures | Not provided at time of registration |
| Overall study start date | 03/07/2002 |
| Completion date | 02/07/2006 |
