Inhaled corticosteroids viral bronchitis

Use of QVAR with a spacer device in children less than 5 years of age is not recommended. In vitro dose characterization studies were performed with QVAR 40 mcg/actuation with the OptiChamber and AeroChamber Plus ® spacer utilizing inspiratory flows representative of children under 5 years old. These studies indicated that the amount of medication delivered through the spacing device decreased rapidly with increasing wait times of 5 to 10 seconds as shown in Table 2. If QVAR is used with a spacer device, it is important to inhale immediately.

The aim of this article is to bring less well recognised adverse effects of inhaled corticosteroids to the attention of prescribers. Whilst inhaled steroids have a more favourable side effect profile than systemic steroids, they are not free from adverse effects. The dose of inhaled steroids used should be carefully monitored, and kept at the lowest dose necessary to maintain adequate control of the patient’s disease process. Be particularly aware of the cumulative effect of co-prescribing various dose forms of corticosteroids (inhaled, intranasal, oral and topical preparations).

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]
