Description
11 DESCRIPTION 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 1-azoniabicyclo[2.2.2]octane, 3-[(hydroxydi-2-thienylacetyl)oxy]-1-(3-phenoxypropyl)-, bromide, (3 R )-. The structural formula is: Aclidinium bromide is a white powder with a molecular formula of C 26 H 30 NO 4 S 2 Br 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 (equivalent to 343 mcg of aclidinium). This results in delivery of 375 mcg aclidinium bromide (equivalent to 322 mcg of aclidinium) 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. Structural Formula

Side Effects (Adverse Reactions)
6 ADVERSE REACTIONS The following adverse reactions are described in greater detail in other sections:
Drug Interactions
7 DRUG INTERACTIONS In vitro studies suggest limited potential for CYP450-related metabolic drug interactions, thus no formal drug interaction studies have been performed with TUDORZA PRESSAIR [see Clinical Pharmacology (12.3) ] . Anticholinergics: May interact additively with concomitantly used anticholinergic medications. Avoid administrations of TUDORZA PRESSAIR with other anticholinergic-containing drugs. ( 7.2 ) 7.1 Sympathomimetics, Methylxanthines, Steroids In clinical studies, concurrent administration of aclidinium bromide and other drugs commonly used in the treatment of COPD including sympathomimetics (short-acting beta 2 agonists), methylxanthines, and oral and inhaled steroids showed no increases in adverse drug reactions. 7.2 Anticholinergics There is a potential for an additive interaction with concomitantly used anticholinergic medications. Therefore, avoid coadministration of TUDORZA PRESSAIR with other anticholinergic-containing drugs as this may lead to an increase in anticholinergic effects.
Contraindications
4 CONTRAINDICATIONS The use of TUDORZA PRESSAIR is contraindicated in the following conditions:
Pregnancy and Breastfeeding
8.1 Pregnancy Risk Summary There are no adequate and well controlled studies of TUDORZA PRESSAIR in pregnant women to inform drug associated risks. No adverse developmental effects were seen with inhalation administration of aclidinium bromide to pregnant rats and rabbits during organogenesis at 15 or 20 times, respectively, the maximum recommended human daily inhaled dose (MRHDID). However, reduced pup weights were seen when pregnant rats continued inhalation administration through lactation at 5 times the MRHDID of aclidinium bromide. Adverse developmental effects occurred when rabbits were orally dosed with aclidinium bromide at approximately 1,400 times the MRHDID [ see Data ]. The estimated background risk of major birth defects and miscarriage of the indicated populations is unknown. In the U.S. general population, the estimated background risk of major birth defects and miscarriage in clinically recognized pregnancies is 2% to 4% and 15% to 20%, respectively. Data Animal Data In an embryo-fetal development study in pregnant rats dosed during the period of organogenesis from gestation days 6-17, no evidence of structural alterations was observed at approximately 15 times the MRHDID [based on summed AUCs of aclidinium bromide and its metabolites at inhaled doses less than or equal to 5.0 mg/kg/day]. However, in a pre- and post-natal development study, decreased pup weights were observed when pregnant rats were exposed from gestation day 6 and continuing during the lactation period at approximately 5 times the MRHDID [based on summed AUCs of aclidinium bromide and its metabolites at inhaled doses greater than or equal to 0.2 mg/kg/day]. Maternal toxicity was also observed at inhaled doses greater than or equal to 0.2 mg/kg/day. In an embryo-fetal development study in pregnant Himalayan rabbits administered inhaled doses of aclidinium bromide during the period of organogenesis from gestation days 6-19, no evidence of structural alterations was observed at...
Overdosage
10 OVERDOSAGE 10.1 Human Experience No case of overdose has been reported in clinical studies with TUDORZA PRESSAIR. There were no systemic anticholinergic or other adverse effects following a single inhaled dose of up to 6,000 mcg aclidinium bromide (7.5 times the RHDD) in 16 healthy volunteers.
How Supplied
16 HOW SUPPLIED/STORAGE AND HANDLING TUDORZA ® PRESSAIR ® (aclidinium bromide inhalation powder) 400 mcg is supplied in a sealed bag and is available in 60 metered doses (NDC 0310-0800-60) and 30 metered doses (NDC 0310-0800-39). The active ingredient is administered using a multi-dose dry powder inhaler, PRESSAIR ® , which delivers 60 doses or 30 doses of aclidinium bromide powder for oral inhalation. The PRESSAIR inhaler is a white and green colored device and is comprised of an assembled plastic dosing mechanism with a dose indicator, a drug-product storage unit containing the drug-product formulation, and a mouthpiece covered by a green protective cap. Store TUDORZA PRESSAIR in a dry place at 25°C (77°F); excursions permitted to 15-30°C (59-86°F) [see USP Controlled Room Temperature] . Do not store the inhaler on a vibrating surface. The PRESSAIR inhaler should be stored inside the sealed bag and only be opened immediately before use. Throw away the bag. Throw away (dispose of) the PRESSAIR inhaler after the marking “0” with a red background shows in the middle of the dose indicator, when the device is empty and locks out, or 45 days after the date you opened the sealed bag that the inhaler comes in, whichever comes first. Keep out of reach of children.
