That ICS should be first line therapy for asthma--con.
Asthma is a heterogeneous disease and it is therefore unrealistic to expect that inhaled corticosteroids (ICS) would be appropriate first line preventer therapy for all children with asthma. There is good theoretical and clinical trial evidence demonstrating that leukotriene receptor antagonists (LTRAs) are more effective than ICS for viral induced wheezing and equivalent to ICS for mild persistent asthma in children. LTRAS do not have the systemic adverse effects of ICS, are generally well tolerated and their once daily oral administration enhances adherence. LTRAs should therefore be first line preventer therapy for children with frequent intermittent or mild persistent asthma while ICS should be reserved as first line treatment for children with moderate to severe persistent asthma. Given the skew in paediatric asthma severity towards the milder end, this effectively means that LTRAs should be tried first in 2 of every 3 children with asthma requiring preventer treatment.
