Why two NDCs? The FDA registers this code as 70515-001-03 — a 5-3-2 layout, and that's what's printed on the package and shown on DailyMed. For insurance claims, every NDC is standardized to a uniform 11-digit 5-4-2 format by adding a zero to the product segment → 70515-0001-03. Same drug, same package — only the format differs.

🩺 Clinical

Label name DUAKLIR PRESSAIR 400-12MCG INH Ingredient Aclidinium Brom/Formoterol Fum
📖 What it is MedlinePlus · NLM

Aclidinium is used as a long term treatment to prevent wheezing, shortness of breath, coughing, and chest tightness in patients with chronic obstructive pulmonary disease (COPD, a group of diseases that affect the lungs and airways) such as chronic bronchitis (swelling of the air passages that lead to the lungs) and emphysema (damage to air sacs in the lungs). Aclidinium is in a class of medications called bronchodilators. It works by relaxing and opening the air passages to the lungs to make breathing easier.

Where does this data come from?
Data sourced from official FDA Structured Product Labeling (SPL) via DailyMedingredient classCode="IACT" elements from the exact product block matched by this NDC. Label-section narrative from DailyMed / the openFDA label index is shown separately when available.

Inactive ingredient FAQ

Are inactive ingredients the same for every manufacturer?
No. Inactive ingredients can differ by manufacturer, dosage form, strength, and package / product version.
Why might an inactive ingredient be missing?
Some SPLs do not provide a complete structured inactive-ingredient list, and older or unusual labels may only include the information in narrative text.
Can inactive ingredients matter?
Yes. They can matter for allergies, intolerances, dyes, gluten / lactose concerns, preservatives, and formulation differences — but confirm with a pharmacist or the manufacturer when it’s clinically important.

💲 Pricing

A drug doesn't have one price. Each row is a different public payment system, and none is what you'd pay at the counter — that depends on your insurance. The ⓘ on each row explains what it measures.

Price systemPer gPer package
Retail pharmacies payNADAC · weekly Not in the retail survey — common for institutional, discontinued, or low-volume packs.

ℹ️
No price is published for this exact package yet. CMS surveys NADAC per package size, so a different pack of the same drug often has one.

Where does this data come from?
NADAC (National Average Drug Acquisition Cost) is the CMS weekly pharmacy-acquisition-cost survey — what pharmacies pay. ASP (Average Sales Price) is the CMS Medicare Part B drug-payment file, published quarterly. Medicaid pays is computed by us from CMS State Drug Utilization Data (total reimbursed ÷ units, trailing 12 months) — gross of rebates and inclusive of dispensing fees, so it reflects what Medicaid paid, not an acquisition cost. Medicare drug plans pay is the median negotiated point-of-sale unit cost across plans listing this NDC in the CMS quarterly Prescription Drug Plan pricing files, before rebates. The VA pays is the federal contract price (FSS, and the statutory Big 4 ceiling where listed) from the VA National Acquisition Center pharmaceutical price file. All are free public government data; each measures a different payer, so the figures are not directly comparable.

Why the date isn’t exact: Generic timing can change because patents may be challenged, settled, licensed, added, removed, or worked around with a narrower label — and FDA approval does not always mean a pharmacy can get the generic today.

🏛️FDA exclusivity
FDA-granted marketing protection. It’s separate from patents and may be shorter than patent protection.
🧪Product / substance patents
Patents covering the active ingredient, product, formulation, or related drug features.
🎯Method-of-use patents
Patents covering specific approved uses. These can sometimes be carved out with a “skinny label,” but not always.
🛈 What do these terms mean?
Patent
Legal protection listed in the Orange Book that may delay generic approval or launch. Issued by the U.S. Patent & Trademark Office.
Substance patent
Covers the active drug molecule itself — the hardest to design around. A generic generally can’t launch until it expires.
Formulation (product) patent
Covers a specific formulation or dosage form. A generic can sometimes work around it with a different formulation.
Method-of-use patent
A patent covering one specific approved use of the drug — not necessarily the whole molecule. A generic can sometimes launch with a “skinny label” that carves out the protected use and keeps the others.
Skinny label
A generic label that omits a still-patented use when the FDA allows it — letting a generic reach the market for the unprotected uses.
Exclusivity
FDA-granted marketing protection, separate from patents — e.g. 5-yr new chemical entity, 7-yr orphan drug, or a +6-month pediatric extension.
Paragraph IV
A generic applicant’s formal challenge to a listed patent. It can potentially lead to earlier generic entry, but often involves litigation or a settlement.
RLD / RS
Reference Listed Drug — the brand product the FDA uses as the reference for generic applications. Reference Standard — the product the FDA expects generics to compare against in bioequivalence testing.
TE / AB rating
FDA therapeutic-equivalence rating. An AB rating generally means the FDA considers a generic therapeutically equivalent to — and substitutable for — the brand.
LOE (loss of exclusivity)
The latest patent or exclusivity currently listed — the loss-of-exclusivity / latest-listed-protection date shown on this page. Paragraph-IV challenges and settlements can move the real date earlier; FDA approval and a manufacturer’s decision to market can move it later.

Built from the FDA Orange Book. The bars above are scaled to each protection’s expiry; the red LOE marker is the last one to lapse.

Common questions
Is there a generic version of DUAKLIR PRESSAIR 400-12MCG INH?
No FDA-approved generic equivalent is currently listed in the FDA Orange Book for DUAKLIR PRESSAIR 400-12MCG INH. Based on the patents and exclusivity currently listed, the Orange Book estimate is that full-label generic entry may be delayed until Mar 2029 — an estimate, not a guaranteed launch date.
The FDA approved a generic — why can’t I get it at my pharmacy yet?
FDA approval and pharmacy availability are two different things. The FDA can approve a generic years before it actually reaches pharmacies, because the brand company may still hold patents or have a settlement that delays the launch. A manufacturer also has to choose to make and sell it, and have supply ready. So a drug can be “FDA-approved generic exists” and still be brand-only at the counter today.
Why do different websites show different generic release dates?
Generic availability is not based on one single date. Some sources use the first exclusivity expiration, some use the last product patent, and others use the latest method-of-use patent. Patent challenges, settlements, licenses, and label carve-outs can also change the real-world launch date. This page shows the underlying Orange Book dates so you can see why estimates may differ.
What does “FDA listed” mean?
It means the product appears in the FDA’s official NDC directory. That’s a good sign a product exists and is intended for the U.S. market, but on its own it does not confirm a pharmacy can fill it today. Where we have recent retail pricing data (NADAC) for a product, we label it “Availability likely” instead.
What does a patent or protection date mean here?
It’s the latest date currently listed in the FDA Orange Book for a patent or exclusivity on the brand product. It can affect when a full generic version becomes widely available — but it is not a guaranteed generic launch date. Generics sometimes arrive earlier (through a settlement or patent challenge) or later (a manufacturer still has to make and sell one).
What does “current Orange Book estimate” mean?
It means we are using the latest patent and exclusivity dates currently listed in the FDA Orange Book. It is not a guaranteed launch date.
Can a generic come out before the last patent expires?
Sometimes. A generic company may challenge a patent, settle with the brand manufacturer, receive a license, or obtain approval with a narrower label that avoids a patented use. In other cases, the last listed protection may delay full-label generic competition.
Can a generic come out after the listed dates?
Yes. Even after patents or exclusivity expire, a generic still needs FDA approval and a manufacturer must choose to market it. Supply, litigation, business decisions, or regulatory issues can delay actual availability.
What is the difference between patents and exclusivity?
Patents are legal protections usually issued by the U.S. Patent and Trademark Office. FDA exclusivity is marketing protection granted by the FDA. They are separate, and either one can affect generic timing.
Why are there multiple patent dates?
One drug can have several patents covering different things: the active ingredient, a formulation, a manufacturing process, or a specific approved use. That is why a page may show several expiration dates instead of one simple generic date.
Built from FDA Orange Book patent and exclusivity data. Dates are refreshed from public FDA data when available; the marker is max(latest patent expiry, latest exclusivity expiry). Paragraph-IV settlements and first-filer 180-day exclusivity can shift the real date; a method-of-use patent may allow an earlier skinny-label generic for non-protected indications. Generic launch timing is an estimate, not a guarantee.
Where does this data come from?
Patents and exclusivity from the FDA Orange Book (small-molecule drugs), refreshed from public FDA data. Generic launch timing is an estimate, not a guarantee.

⚠️ Drug-level data: CMS publishes Part D spending by drug, not by NDC — these figures combine every manufacturer, strength and package size sold under the name Duaklir Pressair. That’s a different level of aggregation than the Medicaid card above, which is specific to this exact 11-digit NDC (pack size included), so the two aren’t directly comparable.

Questions about this listing

Why is there no price listed?
The pricing shown on our NDC pages comes from CMS NADAC, a voluntary survey of retail community pharmacy invoices. CMS does not publish a NADAC for every NDC — packages outside the retail survey (institutional and hospital products, bulk packages, discontinued items, and many OTC items) may never receive one. A missing price reflects the survey's scope, not this product's actual cost, and does not mean the product is free or unavailable.
Is the NDC printed on the package the same as the 11-digit billing NDC?
Yes, they identify this exact package in different formats. The FDA registers it as 70515-001-03, which is what is printed on the packaging and shown on DailyMed. Insurance claims use a fixed 11-digit 5-4-2 format, so the short segment is padded with a leading zero: 70515-0001-03, written without dashes as 70515000103. The Identity section at the top of this page lists every form of this code.
What do the three segments of this NDC mean?
In 70515-0001-03, the first segment (70515) is the labeler code FDA assigned to Covis Pharma US, Inc; the middle segment (0001) identifies this specific product — its ingredient, strength, and dosage form; and the last segment (03) identifies this exact package size and type. Together they name one specific package of one specific product.
Is this package still being marketed?
Yes, per the latest FDA NDC Directory data on this page: this package is listed as actively marketed, with no marketing end date reported by Covis Pharma US, Inc. Listing status can change — the directory data on this page refreshes weekly.
Does this product come in other package sizes?
Yes — the FDA directory lists 1 other package presentation of this same product, including 1 pouch (70515-0001-01). Each has its own NDC and its own page — see the package list near the top of this page.
Who lists this product with the FDA?
Covis Pharma US, Inc is the labeler of record for this NDC — the company under whose FDA-assigned code the package is listed. The labeler may be the manufacturer itself or a distributor marketing the product under its own code.
Do I need a prescription for this product?
This NDC is listed with FDA as a prescription product, so it is dispensed under a prescriber's order. Your pharmacist can tell you whether any over-the-counter forms of the same medication exist.
This page identifies an FDA-listed package (the NDC) and reports public regulatory and pricing data about the listing. It is reference information, not a medical recommendation — talk to your pharmacist or prescriber about your own medication.

⚠️ Warnings and Cautions ~3 min read

5 WARNINGS AND PRECAUTIONS • Asthma-related death: Long-acting beta 2 -adrenergic agonists as monotherapy (without an inhaled corticosteroid) for asthma increase the risk of serious asthma-related events. ( 5.1 ) • Do not initiate in acutely deteriorating COPD or to treat acute symptoms. ( 5.2 ) • Do not use in combination with an additional medicine containing a LABA because of risk of overdose.

( 5.3 ) • If paradoxical bronchospasm occurs, discontinue DUAKLIR PRESSAIR and institute alternative therapy. ( 5.4 ) • Use with caution in patients with cardiovascular disorders. ( 5.6 ) • Use with caution in patients with convulsive disorders, thyrotoxicosis, diabetes mellitus and ketoacidosis.

( 5.7 ) • Be alert to hypokalemia and hyperglycemia. ( 5.8 ) • Worsening of narrow-angle glaucoma may occur. Use with caution in patients with narrow-angle glaucoma and instruct patients to contact a physician immediately if symptoms occur.

( 5.9 ) • Worsening urinary retention may occur. Use with caution in patients with prostatic hyperplasia or bladder-neck obstruction and instruct patients to consult a physician immediately if symptoms occur. ( 5.10 )

5.1Serious Asthma-Related Events-Hospitalizations, Intubations, Death • The safety and efficacy of DUAKLIR PRESSAIR in patients with asthma have not been established. DUAKLIR PRESSAIR is not indicated for the treatment of asthma. [see Contraindications (4) ] . • Use of LABA as monotherapy [without inhaled corticosteroids (ICS)] for asthma is associated with an increased risk of asthma-related death. Available data from controlled clinical trials also suggest that use of LABA as monotherapy increases the risk of asthma-related hospitalization in pediatric and adolescent patients.

These findings are considered a class effect of LABA monotherapy. When LABA are used in fixed-dose combination with ICS, data from large clinical trials do not show a significant increase in the risk of serious asthma-related events (hospitalizations, intubations, death) compared with ICS alone. • A 28-week, placebo-controlled, U.S. trial comparing the safety of another LABA (salmeterol) with placebo, each added to usual asthma therapy, showed an increase in asthma-related deaths in subjects receiving salmeterol (13/13,176 in subjects treated with salmeterol vs 3/13,179 in subjects treated with placebo; relative risk: 4.37 [95% CI: 1.25, 15.34]).

The increased risk of asthma-related death is considered a class effect of LABAs, including formoterol fumarate, one of the active ingredients in DUAKLIR PRESSAIR. • No trial adequate to determine whether the rate of asthma-related deaths is increased in subjects treated with DUAKLIR PRESSAIR has been conducted. • Available data do not suggest an increased risk of death with use of LABA in patients with COPD.

5.2Deterioration of Disease and Acute Episodes DUAKLIR PRESSAIR should not be initiated in patients with acutely deteriorating COPD, which may be a life-threatening condition. DUAKLIR PRESSAIR has not been studied in patients with acutely deteriorating COPD. The use of DUAKLIR PRESSAIR in this setting is inappropriate.

DUAKLIR PRESSAIR is intended as twice daily maintenance treatment for COPD and should not be used for the relief of acute symptoms, i.e., as rescue therapy for treatment of acute episodes of bronchospasm. DUAKLIR PRESSAIR has not been studied in the relief of acute symptoms and extra doses should not be used for that purpose. Acute symptoms should be treated with an inhaled short-acting beta 2 -agonist.

When beginning treatment with DUAKLIR PRESSAIR, patients who have been taking oral or inhaled, short-acting beta 2 -agonists on a regular basis (e.g., four times a day) should be instructed to discontinue the regular use of these drugs and use them only for symptomatic relief of acute respiratory symptoms. When prescribing DUAKLIR PRESSAIR, the healthcare provider should also prescribe an inhaled, short-acting beta 2 -agonist and instruct the patient on h…

🤒 Adverse Reactions ~3 min read

6 ADVERSE REACTIONS LABAs, such as formoterol fumarate, one of the active ingredients in DUAKLIR PRESSAIR, increase the risk of asthma-related death. DUAKLIR PRESSAIR is not indicated for the treatment of asthma [see Warnings and Precautions (5.1) ] . The following adverse reactions are described in greater detail elsewhere in the labeling: • Paradoxical bronchospasm [see Warnings and Precautions (5.4) ] • Immediate hypersensitivity reactions [see Contraindications (4) , Warnings and Precautions (5.5) ] • Cardiovascular effects [see Warnings and Precautions (5.6)] • Worsening of narrow-angle glaucoma [see Warnings and Precautions (5.9) ] • Worsening of urinary retention [see Warnings and Precautions (5.10) ] Most common adverse reactions (incidence ≥ 3% and more common than with placebo) include: upper respiratory tract infection, headache and, back pain.

6.1Clinical Trials Experience Because clinical trials are conducted under widely varying conditions, adverse reaction rates observed in the clinical trials of a drug cannot be directly compared with rates in the clinical trials of another drug and may not reflect the rates observed in practice. The clinical program for DUAKLIR PRESSAIR included 6501 subjects with COPD in 2 placebo-controlled and 1 active-controlled 24-week lung function trials, one long-term safety extension study of 28 weeks and 2 other clinical trials.

A total of 1893 subjects have received at least 1 dose of DUAKLIR PRESSAIR. 24-Week Trials The frequency of common adverse reactions in Table 1 below is based upon pooled data from two, double-blind, placebo-controlled parallel group clinical trials (Trials 1 and 2, n=1729 and n=1669) in 3398 adult patients with moderate to severe COPD. Of these, 60% were male and 94% were Caucasian.

They had a mean age of 64 years and an average smoking history of 46 pack-years, with 49% identified as current smokers. At screening, the mean post-bronchodilator percent predicted forced expiratory volume in 1 second (FEV 1 ) was 54% (range: 28% to 80%) and the mean percent reversibility was 15% (range: -19% to 69%). Table 1 shows all adverse reactions that occurred with a frequency of greater than or equal to 3% in the DUAKLIR PRESSAIR group in the two 24-week placebo-controlled trials where the rates in the DUAKLIR PRESSAIR group exceeded placebo.

3.4Other adverse reactions reported in clinical studies with an incidence of >1% but less than 3% with DUAKLIR PRESSAIR but more common than with placebo were cough, sinusitis, influenza, tooth abscess, insomnia, dizziness, dry mouth, oropharyngeal pain, muscle spasms, musculoskeletal pain, arthralgia, pain in extremity, urinary tract infection, and blood creatine phosphokinase increased. The adverse events reported in the 24-week active-controlled trial were consistent with those observed in 24-week placebo-controlled trials.

Long-Term Safety Extension Trial In a 28-week safety extension trial, 918 subjects who successfully completed Trial 2 were treated for up to an additional 28 weeks for a total treatment period of up to 52 weeks with DUAKLIR PRESSAIR, aclidinium 400 mcg, formoterol fumarate 12 mcg administered twice daily or placebo. Because the subjects continued from Trial 2 into the safety extension trial, the demographic and baseline characteristics of the long-term safety extension trial were similar to those of the placebo-controlled efficacy trials described ab…

🔄 Drug Interactions ~2 min read

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.

( 7.3 ) • Monoamine oxidase inhibitors and tricyclic antidepressants: Use with extreme caution. May potentiate effect of formoterol fumarate on cardiovascular system. ( 7.4 ) • Beta-blockers: Use with caution and only when medically necessary.

( 7.5 ) • Anticholinergics: May interact additively with concomitantly used anticholinergic medications. Avoid administrations of DUAKLIR PRESSAIR with other anticholinergic-containing drugs. ( 7.6 )

7.1Adrenergic Drugs If additional adrenergic drugs are to be administered by any route, they should be used with caution because the sympathetic effects of formoterol, a component of DUAKLIR PRESSAIR, may be potentiated [see Warnings and Precautions (5.7) ] .

7.2Xanthine Derivatives, Steroids Concomitant treatment with xanthine derivatives, or steroids may potentiate any hypokalemic effect of beta-adrenergic agonists such as formoterol, a component of DUAKLIR PRESSAIR.

7.3Non-Potassium Sparing Diuretics The electrocardiographic changes and/or hypokalemia that may result from the administration of non-potassium-sparing diuretics (such as loop or thiazide diuretics) can be acutely worsened by beta-agonists, especially when the recommended dose of the beta-agonist is exceeded. Although the clinical significance of these effects is not known, caution is advised in the coadministration of beta-agonists with non–potassium-sparing diuretics.

7.4Monoamine Oxidase Inhibitors and Tricyclic Antidepressants, QTc Prolonging Drugs DUAKLIR PRESSAIR, as with other drugs containing beta 2 -agonists, should be administered with caution to patients being treated with monoamine oxidase inhibitors, tricyclic antidepressants, or other drugs known to prolong the QTc interval, because the action of adrenergic agonists on the cardiovascular system may be potentiated by these agents. Drugs that are known to prolong the QTc interval have an increased risk of ventricular arrhythmias.

7.5Beta-Blockers Beta-adrenergic receptor antagonists (beta-blockers) and DUAKLIR PRESSAIR may inhibit the effect of each other when administered concurrently. Beta-blockers not only block the therapeutic effects of beta 2 -agonists, such as formoterol, a component of DUAKLIR PRESSAIR, but may produce severe bronchospasm in COPD patients. Therefore, patients with COPD should not normally be treated with beta-blockers.

However, under certain circumstances, e.g., as prophylaxis after myocardial infarction, there may be no acceptable alternatives to the use of beta-blockers in patients with COPD. In this setting, cardioselective beta-blockers could be considered, although they should be administered with caution.

7.6Anticholinergics There is a potential for an additive interaction with concomitantly used anticholinergic medications. Therefore, avoid coadministration of DUAKLIR PRESSAIR with other anticholinergic-containing drugs as this may lead to an increase in anticholinergic effects [see Warnings and Precautions ( 5.3 , 5.4 ) and Adverse Reactions (6) ] .

8 USE IN SPECIFIC POPULATIONS

8.1Pregnancy Risk Summary There are no adequate and well-controlled studies of DUAKLIR PRESSAIR or its individual components, formoterol fumarate or aclidinium bromide, 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] . Formoterol fumarate alone, administered by the oral route, was teratogenic in rats and rabbits at 1,200 and 49,000 times the MRHDID, respectively. Formoterol fumarate was also embryocidal, increased pup loss at birth and during lactation, and decreased pup weight in rats at 85 times the MRHDID.

These adverse effects generally occurred at large multiples of the MRHDID when formoterol fumarate was administered by the oral route to achieve high systemic exposures. No teratogenic, embryocidal, or developmental effects were seen in rats that received inhalation doses up to 280 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. Clinical Considerations Labor or Delivery There are no well-controlled human studies that have investigated the effects of DUAKLIR PRESSAIR during labor and delivery. Because of the potential for beta-agonist interference with uterine contractility, use of DUAKLIR PRESSAIR during labor should be restricted to those patients in whom the benefits clearly outweigh the risk.

Data Animal Data Aclidinium bromide 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 maximum recommended human daily inhaled dose (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 approximately 20 times the MRHDID [based on summed AUCs of aclidinium bromide and its metabolites at inhaled doses less than or equal to 3.6 mg/kg/day]. However, in another embryo-fetal development study in pregnant Himalayan rabbits dosed orally from gestation days 6-19, increased incidences of additional liver lobes (3-5%), as compared to 0% in the control group, were observed at approximately 1,400 times the MRHDID [based on summed AUCs of aclidinium bromide and its metabolites at oral doses greater than or equal to 150 mg/kg/day], and decreased fetal body weights were observed at approximately 2,300 times the MRHDID [based on summed AUCs of aclidinium bromide and its metabolites at oral doses greater than or equal to 300 mg/kg/day].

12 CLINICAL PHARMACOLOGY

12.1Mechanism 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. It has similar affinity to the subtypes of muscarinic receptors M1 to M5.

In the airways, it exhibits pharmacological effects through inhibition of M3 receptors at the smooth muscle leading to bronchodilation. The competitive and reversible nature of antagonism was shown with human and animal origin receptors and isolated organ preparations. In preclinical in vitro as well as in vivo studies, prevention of acetylcholine-induced bronchoconstriction effects was dose-dependent and lasted longer than 24 hours.

The clinical relevance of these findings is unknown. The bronchodilation following inhalation of aclidinium bromide is predominantly a site-specific effect. Formoterol fumarate Formoterol fumarate is a long-acting selective beta 2 -adrenergic receptor agonist (LABA) (beta 2 -agonist).

Inhaled formoterol fumarate acts locally in the lung as a bronchodilator. In-vitro studies have shown that formoterol has more than 200-fold greater agonist activity at beta 2 -receptors than at beta 1 -receptors. The in-vitro binding selectivity to beta 2 -over beta 1 -adrenoceptors is higher for formoterol than for albuterol (5 times), whereas salmeterol has a higher (3 times) beta‑selectivity ratio than formoterol.

Although beta 2 -receptors are the predominant adrenergic receptors in bronchial smooth muscle and beta 1 -receptors are the predominant receptors in the heart, there are also beta 2 -receptors in the human heart comprising 10% to 50% of the total beta-adrenergic receptors. The precise function of these receptors has not been established, but they raise the possibility that even highly selective beta 2 -agonists may have cardiac effects. The pharmacologic effects of beta 2 -adrenoceptor agonist drugs, including formoterol, are at least in part attributable to stimulation of intracellular adenyl cyclase, the enzyme that catalyzes the conversion of adenosine triphosphate (ATP) to cyclic-3', 5'-adenosine monophosphate (cyclic AMP).

Increased cyclic AMP levels cause relaxation of bronchial smooth muscle and inhibition of release of mediators of immediate hypersensitivity from cells, especially from mast cells. In vitro tests show that formoterol is an inhibitor of the release of mast cell mediators, such as histamine and leukotrienes, from the human lung. Formoterol also inhibits histamine-induced plasma albumin extravasation in anesthetized guinea pigs and inhibits allergen-induced eosinophil influx in dogs with airway hyper responsiveness.

The relevance of these in vitro and animal findings to humans is unknown.

12.2Pharmacodynamics Cardiovascular effects DUAKLIR PRESSAIR The effect of DUAKLIR PRESSAIR on cardiac rhythm was assessed in a subset of subjects using 24-hour Holter monitoring in the 24-week placebo-controlled trials. The Holter monitoring population included 114 subjects on DUAKLIR PRESSAIR, 118 subjects on aclidinium bromide 400 mcg, 121 subjects on formoterol fumarate 12 mcg, and 81 subjects on placebo. No clinically meaningful effects on cardiac rhythm were observed.

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[2.2.2]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. Formoterol fumarate, a racemate, is a selective beta 2 -adrenergic agonist.

Its chemical name is (±)-2-hydroxy-5-[(1RS)-1-hydroxy-2-[[(1RS)-2-(4-methoxyphenyl)-1methylethyl]-amino]ethyl]formanilide fumarate dihydrate. The structural formula is: Formoterol fumarate (as a dihydrate) has a molecular weight of 840.91, and its molecular formula is (C 19 H 24 N 2 O 4 ) 2 • C 4 H 4 O 4 •2H 2 O. Formoterol fumarate is a white to yellowish crystalline powder, which is freely soluble in glacial acetic acid, soluble in methanol, sparingly soluble in ethanol and isopropanol, slightly soluble in water, and practically insoluble in acetone, ethyl acetate, and diethyl ether.

DUAKLIR PRESSAIR is a breath-actuated multi-dose dry powder inhaler. Each actuation of DUAKLIR PRESSAIR provides a metered dose of 12 mg of the formulation which contains lactose monohydrate (which may contain milk proteins) as the carrier, 400 mcg of aclidinium bromide (equivalent to 343 mcg of aclidinium), and 12.0 mcg of formoterol fumarate (as a dihydrate, equivalent to 11.5 mcg of formoterol fumarate anhydrous and 9.8 mcg of formoterol). This results in delivery of 396 mcg of aclidinium bromide (equivalent to 340 mcg of aclidinium) and 11.8 mcg of formoterol fumarate (as a dihydrate, equivalent to 11.3 mcg of formoterol fumarate anhydrous and 9.7 mcg of formoterol) from the mouthpiece, based on in vitro testing at an average flow rate of approximately 63 L/min with constant volume of 2 L.

17 PATIENT COUNSELING INFORMATION See FDA-approved Patient Labeling (Patient Information and Instructions for Use) • Serious Asthma-Related Events Inform patients that LABAs, such as formoterol fumarate, one of the active ingredients in DUAKLIR PRESSAIR, when used alone (without an inhaled corticosteroid), increase the risk of serious asthma-related events, including asthma-related death. DUAKLIR PRESSAIR is not indicated for the treatment of asthma. • Not for Acute Symptoms DUAKLIR PRESSAIR is not meant to relieve acute symptoms of COPD and extra doses should not be used for that purpose.

Instruct patients to seek medical attention immediately if they experience a worsening of symptoms or a need for more inhalations of their rescue inhaler than usual. Instruct patients not to stop therapy with DUAKLIR PRESSAIR without physician/provider guidance since symptoms may recur after discontinuation. • Do Not Use Additional Long-Acting Beta 2 -Agonists Instruct patients to not use other medicines containing a LABA. Patients should not use more than the recommended dose of DUAKLIR PRESSAIR.

Instruct patients who have been taking inhaled, short-acting beta-agonists on a regular basis to discontinue the regular use of these products and use them only for the symptomatic relief of acute symptoms. • Paradoxical Bronchospasm Inform patients that DUAKLIR PRESSAIR can cause paradoxical bronchospasm. Advise patients that if paradoxical bronchospasm occurs, patients should discontinue DUAKLIR PRESSAIR. • Visual Effects Eye pain or discomfort, blurred vision, visual halos, or colored images in association with red eyes from conjunctival congestion and corneal edema may be signs of acute narrow-angle glaucoma.

Inform patients to consult a physician immediately should any of these signs and symptoms develop. Inform patients that care must be taken not to allow the powder to enter into the eyes as this may cause blurring of vision and pupil dilation. • Urinary Retention Difficulty passing urine and dysuria may be symptoms of new or worsening prostatic hyperplasia or bladder outlet obstruction. Patients should be instructed to consult a physician immediately should any of these signs or symptoms develop. • Immediate Hypersensitivity Reactions Inform patients that anaphylaxis, angioedema (including swelling of the lips, tongue, or throat), urticaria, rash, bronchospasm, or itching, may occur after administration of DUAKLIR PRESSAIR.

Advise patient to immediately discontinue treatment and consult a physician should any of these signs or symptoms develop. • Risks Associated with Beta 2 -Agonist Therapy Inform patients of adverse effects associated with beta 2 -agonists, such as palpitations, chest pain, rapid heart rate, tremor, or nervousness. • Instructions for Administering DUAKLIR PRESSAIR It is important for patients to understand how to correctly use DUAKLIR PRESSAIR. Instruct patients not to use more than the recommended dose of DUAKLIR PRESSAIR or with other medicines containing LABAs as excessive use may lead to significant cardiovascular effects including fatalities.

Patient Information DUAKLIR ™ PRESSAIR® (DU-aakl-ir PRESS-air) (aclidinium bromide and formoterol fumarate) inhalation powder, for oral Inhalation use Important: Do not get DUAKLIR PRESSAIR in your eyes. What is DUAKLIR PRESSAIR? DUAKLIR PRESSAIR combines an anticholinergic, aclidinium bromide, and a long-acting beta 2 -adrenergic agonist (LABA medicine) formoterol fumarate. • Anticholinergic and LABA medicines help the muscles around the airways in your lungs stay relaxed to prevent symptoms such as wheezing, cough, chest tightness, and shortness of breath.

These symptoms can happen when the muscles around the airways tighten. This makes it hard to breathe. • DUAKLIR PRESSAIR is a prescription medicine that is used to treat COPD. COPD is a chronic lung disease that includes chronic bronchitis, emphysema, or both. • DUAKLIR PRESSAIR is used long term as 1 inhalation 2 times each day to improve symptoms of COPD for better breathing and to reduce the number of flare-ups (the worsening of your COPD symptoms for several days). • DUAKLIR PRESSAIR is not for use to treat sudden symptoms of COPD.

Always have a rescue inhaler (short-acting beta 2 agonist medicine) with you to treat sudden symptoms of COPD. If you do not have a rescue inhaler, contact your healthcare provider to have one prescribed for you. • DUAKLIR PRESSAIR is not for the treatment of asthma. It is not known if DUAKLIR PRESSAIR is safe and effective in people with asthma. • DUAKLIR PRESSAIR should not be used in children.

It is not known if DUAKLIR PRESSAIR is safe and effective in children. Do not use DUAKLIR PRESSAIR if you: • have asthma and you use DUAKLIR PRESSAIR without also using a medicine called an inhaled corticosteroid. • have a severe allergy to milk proteins. Ask your healthcare provider if you are not sure. • are allergic to aclidinium bromide, formoterol fumarate, or any of the ingredients in DUAKLIR PRESSAIR.
