Scientists have examined the adverse effects of zafirlukast in Grown ups and youngsters aged 12 or more mature. Occasional studies of eosinophilia accompanied by vasculitis in people on zafirlukast have emerged.

In vitro scientific tests demonstrated that zafirlukast antagonized the contractile activity of 3 leukotrienes (LTC four, LTD 4 and LTE 4) in conducting airway clean muscle from laboratory animals and individuals. Zafirlukast prevented intradermal LTD 4-induced will increase in cutaneous vascular permeability and inhibited inhaled LTD four-induced influx of eosinophils into animal lungs. Inhalational obstacle scientific tests in sensitized sheep confirmed that zafirlukast suppressed the airway responses to antigen; this involved the two the early- and late-stage reaction and also the nonspecific hyperresponsiveness.

Nonetheless, significant will increase in eosinophil levels may cause really serious adverse effects, which includes swelling (inflammation) of your lungs or blood vessels.
