FORADIL® CERTIHALER® (formoterol fumarate inhalation powder) is a breath-actuated multi-dose dry powder inhaler, which contains a powder formulation of formoterol fumarate intended for oral inhalation only. Each actuation of FORADIL CERTIHALER delivers approximately 8.5 mcg of formoterol fumarate from the mouthpiece (based on in vitro testing at 60 L/min for 2 sec), corresponding to a metered dose of 10 mcg of formoterol fumarate. The weight of the formulation metered is approximately 5.6 mg. Ten mcg of formoterol fumarate metered is equivalent to 8.2 mcg of formoterol base. The delivered inhalation powder also contains lactose monohydrate (which contains trace levels of milk proteins) and magnesium stearate.
