TUDORZA PRESSAIR

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

TUDORZA® PRESSAIR® (aclidinium bromide inhalation powder) is indicated for the maintenance treatment of patients with chronic obstructive pulmonary disease (COPD). TUDORZA PRESSAIR is an anticholinergic indicated for the maintenance treatment of patients with chronic obstructive pulmonary disease (COPD). (1)

The recommended dose of TUDORZA PRESSAIR is one oral inhalation of 400 mcg, twice daily (morning and evening approximately 12 hours apart). For oral inhalation only • One inhalation of TUDORZA PRESSAIR 400 mcg twice daily. (2)

The use of TUDORZA PRESSAIR is contraindicated in the following conditions: • Severe hypersensitivity to milk proteins [see Warnings and Precautions (5.5) ] • Hypersensitivity to aclidinium bromide or any of the excipients [see Warnings and Precautions (5.5) ] • Severe hypersensitivity to milk proteins. (4) • Hypersensitivity to any ingredient. (4)

The following adverse reactions are described in greater detail in other sections: • Paradoxical bronchospasm [see Warnings and Precautions (5.2) ] • Worsening of narrow-angle glaucoma [see Warnings and Precautions (5.3) ] • Worsening of urinary retention [see Warnings and Precautions (5.4) ] • Immediate hypersensitivity reactions [see Warnings and Precautions (5.5) ] Most common adverse reactions (≥3% incidence and greater than placebo) are headache, nasopharyngitis and cough.

In these trials, 636 patients were treated with TUDORZA PRESSAIR at the recommended dose of 400 mcg twice daily. The population had a mean age of 64 years (ranging from 40 to 89 years), with 58% males, 94% Caucasian, and had COPD with a mean pre-bronchodilator forced expiratory volume in one second (FEV 1 ) percent predicted of 48%. Patients with unstable cardiac disease, narrow-angle glaucoma, or symptomatic prostatic hypertrophy or bladder outlet obstruction were excluded from these trials. Table 1 shows all adverse reactions that occurred with a frequency of greater than or equal to 1% in the TUDORZA PRESSAIR group in the two 3-month and one 6-month placebo-controlled trials where the rates in the TUDORZA PRESSAIR group exceeded placebo. Table 1: Adverse Reactions (% Patients) in Placebo-Controlled Clinical Trials Treatment Adverse Reactions TUDORZA PRESSAIR Placebo Preferred Term (N=636) (N=640) n (%) n (%) Headache 42 (6.6) 32 (5.0) Nasopharyngitis 35 (5.5) 25 (3.9) Cough 19 (3.0) 14 (2.2) Diarrhea 17 (2.7) 9 (1.4) Sinusitis 11 (1.7) 5 (0.8) Rhinitis 10 (1.6) 8 (1.2) Toothache 7 (1.1) 5 (0.8) Fall 7 (1.1) 3 (0.5) Vomiting 7 (1.1) 3 (0.5) In addition, among the adverse reactions observed in the clinical trials with an incidence of less than 1% were diabetes mellitus, dry mouth, 1 st degree AV block, osteoarthritis, cardiac failure, and cardio-respiratory arrest. Long-term Safety Trials TUDORZA PRESSAIR was studied in three long-term safety trials, two double blind and one open label, ranging from 40 to 52 weeks in patients with moderate to severe COPD. Two of these trials were extensions of the 3-month trials, and one was a dedicated long-term safety trial. In these trials, 891 patients were treated with TUDORZA PRESSAIR at the recommended dose of 400 mcg twice daily. The demographic and baseline characteristics of the long-term safety trials were similar to those of the placebo-controlled trials. The adverse events reported in the long-term safety trials were similar to those occurring in the placebo-controlled trials of 3 to 6 months. No new safety findings were reported compared to the placebo-controlled trials. Long-Term Trial of up to 3-Years In a long-term safety trial with 3630 moderate to very severe COPD patients with previous major cardiac events or cardiovascular risk factors at baseline, the adverse reactions reported with a frequency ≥2% in the TUDORZA PRESSAIR group in which the exposure-adjusted incidence rate exceeds the placebo group were nausea, back pain, cough, hypertension, sinusitis, constipation, arthralgia, anemia, muscle spasms, cardiac failure congestive, cellulitis, and gastroesophageal reflux disease. No other new adverse reactions were identified. 6.2 Postmarketing Experience The following adverse reactions have been identified during postapproval use of drug TUDORZA PRESSAIR. Because these reactions are reported voluntarily from a population of uncertain size, it is not always possible to reliably estimate their frequency or establish a causal relationship to drug exposure. In postmarketing experience with TUDORZA PRESSAIR, immediate hypersensitivity reactions, including anaphylaxis, angioedema (including swelling of the lips, tongue, or throat), urticaria, rash, bronchospasm, or itching have been reported. Additionally, nausea, dysphonia, blurred vision, urinary retention, tachycardia, and stomatitis have been observed.

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.
