Overview
11 DESCRIPTION DUAKLIR PRESSAIR consists of a dry powder formulation of aclidinium bromide and formoterol fumarate for oral inhalation only. Aclidinium bromide, is an anticholinergic with specificity for muscarinic receptors. Aclidinium bromide is a synthetic, quaternary ammonium compound, chemically described as 1-azoniabicyclo[2.2.
Mechanism of Action
12 CLINICAL PHARMACOLOGY 12.1 Mechanism of Action DUAKLIR PRESSAIR DUAKLIR PRESSAIR contains two bronchodilators: aclidinium a long-acting muscarinic antagonist (also known as an anticholinergic) and formoterol a long-acting beta 2 -adrenergic agonist. Further information regarding these two substances is provided below. The mechanism of action described below for the individual components apply to DUAKLIR PRESSAIR. These drugs represent two different classes of medications (a long-acting antimuscarinic agent and a selective long-acting beta 2 -adrenergic receptor agonist) that have different effects on clinical and physiological indices of COPD. Aclidinium bromide Aclidinium bromide is a long-acting antimuscarinic agent, which is often referred to as an anticholinergic.
Indications
- 1 INDICATIONS AND USAGE DUAKLIR PRESSAIR is a combination of aclidinium bromide (an anticholinergic) and formoterol fumarate (a LABA) indicated for the maintenance treatment of patients with chronic obstructive pulmonary disease (COPD). Limitations of Use: DUAKLIR PRESSAIR is not indicated for the relief of acute bronchospasm or for the treatment of asthma [see Warnings and Precautions ( 5.1 , 5.4 )] . DUAKLIR PRESSAIR is a combination of aclidinium bromide an anticholinergic, and formoterol fumarate, a long-acting beta 2 -adrenergic agonist (LABA) indicated for the maintenance treatment of...

Interactions
- 7 DRUG INTERACTIONS No formal drug interaction studies have been performed with DUAKLIR PRESSAIR. • Use of other adrenergic by any route may potentiate the effect of DUAKLIR PRESSAIR. Use with caution. ( 5.3 , 7.1 ) • Xanthine derivatives, steroids, diuretics or non-potassium sparing diuretics may potentiate hypokalemia or ECG changes. Use with caution. ( 7.2 , 7.3 ) • Diuretics: Use with caution. Electrocardiographic changes and/or hypokalemia associated with non-potassium sparing diuretics may worsen with concomitant beta 2 -agonists. ( 7.
