Safety of anti-inflammatory drugs in children with asthma

Purpose of review Inhaled corticosteroids (ICS) are widely used as the first-line treatment of asthma. When the disease is not controlled by standard doses of ICS, other anti-inflammatory drugs should be considered. The aim of this report is to review the main adverse events induced by anti-inflammatory drugs in children with asthma and discuss possible actions to prevent or mitigate these effects. Recent findings Proper interpretation of ICS safety studies requires knowledge of the pharmaceutical properties and delivery device systems of the different ICS available. Genetic variants affecting susceptibility to corticosteroid-induced adrenal suppression were found in children and adults who use ICS to treat their asthma. There is evidence of the association between montelukast use and neuropsychiatric events. Benefits of ICS, properly prescribed and used, outweigh their potential adverse effects. There is substantial evidence that the combination of ICS with long-acting beta2 agonists is safe for asthmatic children. Awareness of the potential risks of neuropsychiatric events in children taking montelukast should inform the clinicians' prescribing practices. Omalizumab is generally well-tolerated, but the evidence on the safety of other biologic agents in children is scanty. The risk of systemic adverse events with anti-inflammatory drugs must be balanced against the risks of uncontrolled asthma and/or frequent oral steroid use.
