lansoprazole has been researched along with Bronchitis in 1 studies
Lansoprazole: A 2,2,2-trifluoroethoxypyridyl derivative of timoprazole that is used in the therapy of STOMACH ULCERS and ZOLLINGER-ELLISON SYNDROME. The drug inhibits H(+)-K(+)-EXCHANGING ATPASE which is found in GASTRIC PARIETAL CELLS. Lansoprazole is a racemic mixture of (R)- and (S)-isomers.
Bronchitis: Inflammation of the large airways in the lung including any part of the BRONCHI, from the PRIMARY BRONCHI to the TERTIARY BRONCHI.

Presence and degree of airway hyperresponsiveness; change from baseline to 24 weeks for airways reactivity assessed by methacholine post-diluent baseline (PC20) after medication holds (NCT00442013)
Timeframe: Measured at Weeks 0 and 24
| Intervention | mg/mL (Mean) |
|---|---|
| Lansoprazole Group | 2.6 |
| Placebo Group | 2.5 |
ASUI is a utility score that ranges from 0 to 1, with higher values indicating better asthma control; info obtained from questionnaire about asthma symptoms; number presents an average of the change from baseline to all follow-up points (NCT00442013)
Timeframe: Measured at Weeks 0, 4, 8, 12, 16, 20, 24
| Intervention | score (Mean) |
|---|---|
| Lansoprazole Group | 0.86 |
| Placebo Group | 0.88 |
Scores range from 1 to 7 with higher values indicating better asthma-related quality of life; questionnaire measures functional impairments that are most troublesome to children as a result of their asthma; number presents an average of the change from baseline to all follow-up points (NCT00442013)
Timeframe: Measured at Weeks 0, 4, 8, 12, 16, 20, 24
| Intervention | score (Mean) |
|---|---|
| Lansoprazole Group | 5.8 |
| Placebo Group | 6.0 |
Score ranges from 0 to 6, a lower score indicated better asthma control. Scores above 1.5 are indicative of poor asthma control; score obtained from questionnaire with 6 questions related to asthma control and FEV (amount of air expired in the first second during a forced expiratory maneuver); number presents an average of the change from baseline to all follow-up points (NCT00442013)
Timeframe: Measured at Weeks 0, 4, 8, 12, 24
| Intervention | score (Mean) |
|---|---|
| Lansoprazole Group | 1.1 |
| Placebo Group | 1.0 |
A measure of pulmonary function, specifically the amount of expired air in the first second during a forced expiratory maneuver while seated; test performed at least 4 hours after last dose of short-acting bronchodilator and at least 12 hours after long-acting bronchodilator; number presents an average of the change from baseline to all follow-up points (NCT00442013)
Timeframe: Measured at Weeks 0, 4, 8, 12, 16, 20, 24
| Intervention | Liters (Mean) |
|---|---|
| Lansoprazole Group | 2.2 |
| Placebo Group | 2.3 |
"Episodes of poor asthma control are defined as any one of the following:~2 consecutive days with peak flow at less than 70% of baseline~prescription of oral corticosteroids for asthma~seeking urgent medical care for asthma symptoms~EPAC was measured by review of daily diaries that were maintained over the entire course of followup, i.e, 24 weeks" (NCT00442013)
Timeframe: Measured daily for 24 weeks by diary
