Long acting beta agonist and steroid inhaler

While the use of inhaled LABAs are still recommended in asthma guidelines for the resulting improved symptom control, [22] further concerns have been raised, by a large meta-analysis of the pooled results from 19 trials with 33,826 participants, that salmeterol may increase the small risks of asthma deaths, and this additional risk is not reduced with the additional use of inhaled steroids (., as with the combination product fluticasone/salmeterol ). [23] This seems to occur because although LABAs relieve asthma symptoms, they also promote bronchial inflammation and sensitivity without warning. [24]

In patients 5-12 years of age, the numbers and percent of patients who reported treatment-emergent adverse reactions were comparable in the 12 mcg twice daily and placebo groups. In general, the pattern of the treatment-emergent adverse reactions observed in children differed from the usual pattern seen in adults. Treatment-emergent adverse reactions that were more frequent in the formoterol group than in the placebo group reflected infection/inflammation ( viral infection , rhinitis , tonsillitis , gastroenteritis ) or abdominal complaints ( abdominal pain , nausea, dyspepsia ).

Trough FEV 1
Trough FEV 1 data were available in 46 studies (n = 47,409). At six months, 41 pairwise comparisons were made between 20 treatments in 31 studies (n = 29,271). As for SGRQ, combination LABA/ICS was the highest ranked class, with a mean improvement over placebo of mL at six months (95% CrI to ) and slightly less at 12 months ( mean difference ( MD ) 100, 95% CrI to ). LAMAs ( MD , 95% CrI to ) and LABAs ( MD , 95% CrI to ) showed roughly equivalent results at six months, and ICSs were the fourth ranked class ( MD , 95% CrI to ). As with SGRQ, initial differences between classes were not so prominent at 12 months. Indacaterol and salmeterol/fluticasone were ranked slightly better than others in their class, and formoterol 12, aclidinium, budesonide and formoterol/budesonide combination were ranked lower within their classes. All credible intervals for individual rankings were wide.
