Montelukast 4 mg once daily at bedtime for 12 weeks in pre-school children with mild-to-moderate persistent asthma (n=689) |
Montelukast superior to placebo on: percentage asthma-free days, daytime asthma symptoms, night-time asthma symptoms, days with asthma symptoms, need for SABA or oral corticosteroids, physician's global evaluation No significant difference vs placebo in exacerbations rate, caregiver's global evaluation, quality of life Benefits observed from first day No difference vs placebo in adverse event rate |
|
Knorr et al., 19989 Becker et al., 200422 |
Montelukast 5 mg once daily at bedtime for 8 weeks in school children with persistent asthma (n=336) Included children with moderately severe (FEV150-85% predicted) asthma One-third taking ICS |
Montelukast superior to placebo on: FEV1improvement, SABA use, days with asthma exacerbations (21% vs 26%), quality of life No significant difference vs placebo on: absenteeism from school, nocturnal awakening, daytime asthma symptom score. Onset of action rapid and sustained No difference vs placebo in adverse event rate In subgroup with milder asthma (FEV1> 75% predicted), montelukast superior to placebo on: FEV1improvement, PEF, night-time wakening, quality of life |

|
Phipatanakul et al., 200242
|
School children with asthma triggered by exposure to cat allergens (n=18)
|

|
|
Johnston et al., 200731
|
6-week trial of montelukast during predictable annual epidemic of asthma exacerbations in children taking usual treatment (n=194)> |
Montelukast superior to placebo on following outcome measures: reduction in days with worse asthma symptoms and reduction in unscheduled physician visits for asthma Benefit seen in both ICS and non-ICS subgroups |
|
|
Randomised comparative trials
|
Garcia Garcia et al., 200511
|
Montelukast 5 mg once daily vs fluticasone 100 mcg twice daily in school children with mild persistent asthma for 12 months (n=994) Designed to demonstrate non-inferiority for primary outcome: change from baseline in % days free of rescue medications (e.g. SABA, systemic corticosteroids) |
Montelukast not inferior to ICS on primary outcome Fluticasone superior on: FEV1, days without SABA, quality of life, systemic corticosteroid requirement, acute asthma episodes Both montelukast and fluticasone well tolerated |
|
Luskin et al., 200325
|
Montelukast vs fluticasone in school children with mild persistent asthma (n=104) 12-month prospective open-label observational study |
Montelukast and fluticasone equally effective on: emergency visits, hospitalisation, symptoms at study completion, SABA use, oral prednisolone use. Montelukast superior on adherence |
|
|
Sorkness et al., 200726 |
Montelukast once daily vs fluticasone 100 mcg twice daily for 48 weeks in school children with mild-to-moderate persistent asthma |
Fluticasone superior on: symptom-free days, SABA use, improvement in number of asthma control days, improvement in episode-free days, FEV1, morning and evening PEF No difference for growth over 48 weeks |
|
|
Zeiger et al., 200627
|
Montelukast vs fluticasone for 16 weeks in school children with mild-to- moderate persistent asthma |
Fluticasone superior to montelukast on: number of asthma control days, Asthma Control Questionnaire, SABA use, FEV1, peak expiratory flow |
|
|
Ostrom et al., 200528 |
Montelukast 5 mg once daily vs fluticasone 50 mcg twice daily for 12 weeks in school children (n=342) with moderate-to-severe persistent asthma (baseline FEV160-85% predicted) |
Fluticasone superior to montelukast on: FEV1, morning and evening PEF, percentage rescue-free days, night-time symptom score, mean total symptom score, SABA use |
|
|
Jat et al., 200629 |
Combination montelukast 5 mg once + budesonide 200 mcg daily vs budesonide 400 mcg/day alone in children with moderate persistent asthma |
Similar efficacy on: FEV1, asthma symptom scores Budesonide 400 mcg/day markedly superior to montelukast plus low-dose budesonide on exacerbation rate (33.3% vs 9.1%; P < 0.01) |
|
|
Lemanske et al., 200524 |
Comparison of three step-up therapies in random order in children (6–17 years) with uncontrolled asthma despite 200 mcg fluticasone daily (n=182): 500 mcg fluticasone daily vs 200 mcg fluticasone + 100 mcg salmeterol daily vs 100 mcg fluticasone + montelukast |
Response to step-up treatments was highly variable. |
|
| Intermittent asthma | |||
|
Randomised placebo-controlled trials
|
Bisgaard et al., 200330 |
Long-term (12 months) montelukast in pre-school children with intermittent asthma and a history of recurrent viral-induced exacerbations taking ICS (n=549) |
Montelukast superior to placebo on: exacerbation rate, ICS requirement |
|
Robertson et al., 20073 |
12-month study of parent-initiated montelukast course commenced at onset of viral infection or asthma symptoms in school children with intermittent asthma |
Montelukast superior to placebo on: reduction in symptoms, days off school, need for doctor visits Non-significant trend favouring montelukast for: specialist attendances and hospitalisations, duration of episode, SABA use, prednisolone use |
|
|
Randomised comparative trials |
Bacharier et al., 200832 |
12-month study of comparing 7-day course of budesonide via nebuliser vs montelukast vs placebo (in addition to SABA) at onset of respiratory infections in preschool children (12–59 months) with moderate-to-severe intermittent wheezing (n=238) |
No difference between treatment groups on following outcome measures: proportion of episode-free days, oral corticosteroid use, health care use, quality of life, linear growth |
| Exercise-induced asthma | |||
|

No difference between treatment groups on following outcome measures: proportion of episode-free days, oral corticosteroid use, health care use, quality of life, linear growth |
|
|
