Single Dose Study of the Effect of Formoterol Fumarate in Combination With Mometasone Furoate Inhaled Via a Pressurized Metered Dose Inhaler (pMDI) in Children Aged 5-11 Years Old With Persistent Asthma

This study is being conducted to compare the pharmacodynamics (bronchodilation, onset and duration of action), of a single dose of formoterol fumarate in combination with mometasone furoate to placebo in children of 5-11 years with persistent asthma. The study will also assess the bronchodilatory effect of a single dose of formoterol fumarate alone and in combination with mometasone furoate delivered via a pressurized metered dose inhaler (pMDI) to the bronchodilatory effect of formoterol fumarate delivered via a dry powder inhaler (DPI). Furthermore, pharmacokinetic assessments of plasma and urine will also be conducted throughout the study to assess systemic exposure following administration of the study medication.
