(aclidinium bromide) Inhalation Powder
TUDORZA PRESSAIR consists of a dry powder formulation of aclidinium bromide for oral inhalation only.
Aclidinium bromide, the active component of TUDORZA PRESSAIR is an anticholinergic with specificity for muscarinic receptors. Aclidinium bromide is a synthetic, quaternary ammonium compound, chemically described as 1Azoniabicyclo[2.2.2]octane, 3-[(hydroxydi-2-thienylacetyl)oxy]-1-(3phenoxypropyl)-, bromide, (3R)-. The structural formula is:
Aclidinium bromide is a white powder with a molecular formula of C26H30NO4S2Br and a molecular mass of 564.56. It is very slightly soluble in water and ethanol and sparingly soluble in methanol.
TUDORZA PRESSAIR is a breath-actuated multi-dose dry powder inhaler. Each actuation of TUDORZA PRESSAIR provides a metered dose of 13 mg of the formulation which contains lactose monohydrate (which may contain milk proteins) as the carrier and 400 mcg of aclidinium bromide. This results in delivery of 375 mcg aclidinium bromide from the mouthpiece, based on in vitro testing at an average flow rate of 63 L/min with constant volume of 2 L. The amount of drug delivered to the lungs will vary depending on patient factors such as inspiratory flow rate and inspiratory time. The PRESSAIR inhaler delivers the target dose at flow rates as low as 35 L/min. Based on a study in adult patients with moderate (N=24) and severe (N=24) COPD the mean peak inspiratory flow (PIF) was 95.3 L/min (range: 54.6 to 129.4 L/min) and 88.7 L/min (range: 72.0 to 106.4 L/min) respectively.
