The remaining trial compared non-equivalent doses (relative potency of fluticasone was greater at the doses given) and found FP to be superior to BUD for symptoms purchase suhagra 100mg online, rescue medicine use generic 100mg suhagra visa, and missed days of work, but found no difference in exacerbations. Budesonide compared with mometasone 48 49 One fair-rated 12-week RCT and one fair-rated 8-week trial compared BUD and mometasone. Overall, the trials reported no significant differences for equipotent doses for most outcomes of interest, but there were some dose-related differences favoring mometasone over BUD when comparing non-equipotent doses. The 12-week trial randomized 730 persons 12 years and older with moderate persistent asthma to medium dose (800 mcg/day) BUD or low-, 48 medium-, or high-dose (200, 400, 800 mcg/day, respectively) mometasone. They found no statistically significant differences between medium-dose BUD and medium-dose mometasone for symptoms or nocturnal awakenings, but patients treated with medium-dose mometasone had a greater decrease in rescue medicine use than those treated with medium-dose BUD (-90. The 8-week trial compared once daily low-dose (400 mcg/day) BUD with once daily medium-dose (440 mcg/day) mometasone in 262 persons 49 12 years and older with moderate persistent asthma. The trial reported statistically significant differences in evening asthma symptoms (P < 0. Budesonide compared with triamcinolone 50 One fair-rated 52-week RCT met our inclusion/exclusion criteria for this comparison. The trial randomized 945 adults ≥18 with mild, moderate, or severe persistent asthma to BUD DPI (mean dose at start and end: 941. On average, patients were treated with medium doses, but starting doses and dose adjustments were left to the discretion of the clinical investigator. Patients treated with BUD had Controller medications for asthma 33 of 369 Final Update 1 Report Drug Effectiveness Review Project greater improvements in symptom- and episode-free days (P < 0. Ciclesonide compared with flunisolide We did not identify any good or fair quality systematic reviews or head-to-head trials that compared ciclesonide to flunisolide. Ciclesonide compared with fluticasone 63-70 Eight fair-quality RCTs meeting our inclusion criteria compared ciclesonide with fluticasone. Three were conducted in subjects with mild to severe persistent asthma; two in 64, 65 70 subjects with moderate persistent asthma; and one each in mild to moderate and moderate 63 to severe persistent asthma. One trial did not report sufficient information to determine the 66 66 severity of persistent asthma. All but one trial compared equipotent doses of ICSs. Five of the trials comparing equipotent doses compared low dose ciclesonide with low dose fluticasone; 64 63 one compared medium doses and one compared high doses. All but one trial used HFA-MDI 64 for delivery of both medications. All eight RCTs were funded by pharmaceutical companies producing ciclesonide. Overall, the evidence from these studies supports the conclusion that there is no difference in the outcomes of interest between equipotent doses of ciclesonide and FP. All seven trials comparing equipotent doses reported non-inferiority of ciclesonide compared to FP or no statistically significant difference for the outcomes of interest with one exception. All of the trials used some measure to assess symptoms and rescue medication use; all but one assessed exacerbations; and four assessed quality of life. The one exception was reported in a 12 week trial of 474 subjects, finding greater improvement in quality of life with ciclesonide than with FP 64 (mean change from baseline in AQLQ: 0. The same trial reported non-inferiority or no statistically significant difference between medications for symptoms. We conducted meta-analyses of these studies for exacerbations, symptoms, and rescue medication use and found no statistically significant differences between ciclesonide and FP (Appendix I). There was no statistically significant difference between ciclesonide and FP for exacerbations requiring treatment with oral steroids (OR 0. There was no significant statistical 2 heterogeneity for any of these analyses (I = 0 for all). Ciclesonide compared with mometasone We did not identify any good or fair quality systematic reviews or head-to-head trials that compared ciclesonide with mometasone. Ciclesonide compared with triamcinolone We did not identify any good or fair quality systematic reviews or head-to-head trials that compared ciclesonide with triamcinolone.

Flunisolide compared with fluticasone 51 We found two RCTs reported in one publication that compared flunisolide and fluticasone meeting our inclusion/exclusion criteria. Both were fair-quality trials comparing non-equipotent doses that randomized patients to high-dose FP MDI (500 mcg/d) or medium-dose flunisolide MDI (1000 mcg/d). One was an 8-week double-blind RCT (N = 321) and the other was a 6-week open-label RCT (N = 332). There was a trend toward greater improvement in symptom-free days for patients treated with high-dose FP (P NR for either). Flunisolide compared with mometasone We did not identify any good or fair quality systematic reviews or head-to-head trials that compared beclomethasone to flunisolide. Flunisolide compared with triamcinolone We did not identify any good or fair quality systematic reviews or head-to-head trials that compared beclomethasone to flunisolide. Fluticasone compared with mometasone 52, 57, Three fair-rated trials comparing FP with mometasone met our inclusion/exclusion criteria. The investigators found no statistically significant differences at endpoint between patients treated with medium-dose fluticasone and those treated with medium- and high-dose mometasone with respect to wheeze and cough scores, nighttime awakenings, or rescue medication use (P > 0. However, patients treated with medium-dose fluticasone had significantly greater improvement in the number of nighttime awakenings (P < 0. In addition, patients on medium-dose fluticasone had significantly better morning difficulty breathing scores than did patients on either low- or medium-dose mometasone (P < 0. Another study was a multinational trial (N=203) that compared high dose mometasone 57 (800 mcg/day) with high dose fluticasone (1000 mcg/day) for 12 weeks. The investigators found no statistically significant differences at endpoint with respect to rescue medication use, symptoms, and exacerbations. The third study did not compare equipotent doses; it compared 71 medium dose mometasone with high dose fluticasone. Fluticasone compared with triamcinolone 53-55 Three fair-rated trials comparing FP to TAA met our inclusion/exclusion criteria. The only 53 one of the three trials comparing equipotent doses found greater improvements in subjects 54, 55 treated with FP. The other two trials comparing non-equipotent doses reported greater improvements for FP-treated subjects for some outcomes and no difference for the others. Subjects were at least 12 years of age and were poorly controlled on ICS therapy. FP-treated subjects had better improvements in symptoms, nighttime awakenings, and rescue medicine use. Controller medications for asthma 35 of 369 Final Update 1 Report Drug Effectiveness Review Project 54, 55 The two comparing non-equipotent doses were similarly designed fair-rated RCTs conducted in 24 outpatient centers. Subjects in both were randomized to medium-dose FP (500 mcg/day by DPI), low-dose TAA (800 mcg/day by MDI with spacer), or placebo for 24 weeks. Both were conducted in subjects 12 years or older previously being treated with ICS. No differences were found in symptom scores or in the percentage of symptom-free days. Subjects treated with FP had greater improvements in rescue medicine requirements in both studies than those treated with TAA. One of the trials reported greater improvement in nighttime 55 54 awakenings for those treated with FP, but the other reported no difference. One reported significantly better improvements in quality of life for FP-treated patients compared to TAA- 55 treated patients.
