lansoprazole and Respiratory Tract Infections

lansoprazole has been researched along with Respiratory Tract Infections in 7 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.

Respiratory Tract Infections: Invasion of the host RESPIRATORY SYSTEM by microorganisms, usually leading to pathological processes or diseases.

Trial Outcomes

Airways Reactivity (Assessed by Methacholine PC20)

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

Interventionmg/mL (Mean)
Lansoprazole Group2.6
Placebo Group2.5

Asthma Symptom Utility Index (ASUI)

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

Interventionscore (Mean)
Lansoprazole Group0.86
Placebo Group0.88

Asthma-specific Quality of Life

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

Interventionscore (Mean)
Lansoprazole Group5.8
Placebo Group6.0

Change in Juniper Asthma Control Score (ACS)

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

Interventionscore (Mean)
Lansoprazole Group1.1
Placebo Group1.0

Pre-bronchodilator Forced Expiratory Volume in 1 Second (FEV1)

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

InterventionLiters (Mean)
Lansoprazole Group2.2
Placebo Group2.3

Rate of Episodes of Poor Asthma Control (EPAC)

"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
