Mechanism Of Action
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 receptor 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.
In a thorough QT Study, 200 mcg and 800 mcg TUDORZA PRESSAIR was administered to healthy volunteers once daily for 3 days; no effects on prolongation of QT interval were observed using QTcF heart-rate correction methods.
Additionally, the effect of TUDORZA PRESSAIR on cardiac rhythm was assessed in 336 COPD patients, 164 patients received aclidinium bromide 400 mcg twice daily and 172 patients received placebo, using 24-hr Holter monitoring. No clinically significant effects on cardiac rhythm were observed.
The absolute bioavailability of aclidinium bromide is approximately 6% in healthy volunteers. Following twice-daily oral inhalation administration of 400 mcg aclidinium bromide in healthy subjects, peak steady state plasma levels were observed within 10 minutes after inhalation.Distribution
Aclidinium bromide shows a volume of distribution of approximately 300 L following intravenous administration of 400 mcg in humans.Metabolism
Clinical pharmacokinetics studies, including a mass balance study, indicate that the major route of metabolism of aclidinium bromide is hydrolysis, which occurs both chemically and enzymatically by esterases. Aclidinium bromide is rapidly and extensively hydrolyzed to its alcohol and dithienylglycolic acid derivatives, neither of which binds to muscarinic receptors and are devoid of pharmacologic activity.
Therefore, due to the low plasma levels achieved at the clinically relevant doses, aclidinium bromide and its metabolites are not expected to alter the disposition of drugs metabolized by the human CYP450 enzymes.Elimination
Total clearance was approximately 170 L/h after an intravenous dose of aclidinium bromide in young healthy volunteers with an inter-individual variability of 36%. Intravenously administered radiolabelled aclidinium bromide was administered to healthy volunteers and was extensively metabolized with 1% excreted as unchanged aclidinium. Approximately 54% to 65% of the radioactivity was excreted in urine and 20% to 33% of the dose was excreted in feces. The combined results indicated that almost the entire aclidinium bromide dose was eliminated by hydrolysis. After dry powder inhalation, urinary excretion of aclidinium is about 0.09% of the dose and the estimated effective half-life is 5 to 8 hours.
Formal drug interaction studies were not performed. In vitro studies using human liver microsomes indicated that aclidinium bromide and its major metabolites do not inhibit CYP450, 1A2, 2A6, 2B6, 2C8, 2C9, 2C19, 2D6, 2E1, 3A4/5 or 4A9/11 at concentrations up to 1,000-fold higher than the maximum plasma concentration that would be expected to be achieved at the therapeutic dose. Therefore, it is unlikely that aclidinium bromide causes CYP450 related drug interactions [see DRUG INTERACTIONS].
Specific PopulationsElderly Patients
The pharmacokinetic profile of aclidinium bromide and its main metabolites was assessed in 12 elderly COPD patients (aged 70 years or older) compared to a younger cohort of 12 COPD patients (40-59 years) that were administered 400 mcg aclidinium bromide once daily for 3 days via inhalation. No clinically significant differences in systemic exposure (AUC and Cmax) were observed when the two groups were compared. No dosage adjustment is necessary in elderly patients [Use In Specific Populations].Renal Impairment
The impact of renal disease upon the pharmacokinetics of aclidinium bromide was studied in 18 subjects with mild, moderate, or severe renal impairment. Systemic exposure (AUC and Cmax) to aclidinium bromide and its main metabolites following single doses of 400 mcg aclidinium bromide was similar in renally impaired patients compared with 6 matched healthy control subjects. No dose adjustment is necessary in renally impaired patients [see Use in Specific Populations].Hepatic Impairment
The effects of hepatic impairment on the pharmacokinetics of aclidinium bromide were not studied. However, hepatic insufficiency is not expected to have relevant influence on aclidinium bromide pharmacokinetics, since it is predominantly metabolized by chemical and enzymatic hydrolysis to products that do not bind to muscarinic receptors [see Use in Specific Populations].
Chronic Obstructive Pulmonary Disease (COPD)
The TUDORZA PRESSAIR clinical development program included a dose-ranging trial (Trial A) for nominal dose selection and three confirmatory trials (Trials B, C, and D).Dose-Ranging Trial
Trial A was a randomized, double-blind, placebo-controlled, active-controlled, crossover trial with 7-day treatment periods separated by 5-day washout periods. Trial A enrolled 79 patients who had a clinical diagnosis of COPD, were 40 years of age or older, had a history of smoking at least 10 pack-years, had a forced expiratory volume in one second (FEV1) of at least 30% and less than 80% of predicted normal value, and a ratio of FEV1 over forced vital capacity (FEV1/FVC) of less than 0.7. Trial A included TUDORZA PRESSAIR doses of 400 mcg, 200 mcg and 100 mcg twice daily, formoterol active control, and placebo. Trial A demonstrated that the effect on trough FEV1 and serial FEV1 in patients treated with the TUDORZA PRESSAIR 100 mcg twice daily and 200 mcg twice daily doses was lower compared to patients treated with the TUDORZA PRESSAIR 400 mcg twice daily dose (Figure 1).
Figure 1: Change from baseline in FEV1Over Time (prior to and after administration of study drug) at Week 1 in Trial A
Trials B, C, and D were three randomized, double-blind, placebo-controlled trials in patients with COPD. Trials B and C were 3 months in duration, and Trial D was 6 months in duration. These trials enrolled 1,276 patients who had a clinical diagnosis of COPD, were 40 years of age or older, had a history of smoking at least 10 pack-years, had an FEV1 of at least 30% and less than 80% of predicted normal value, and a ratio of FEV1/FVC of less than 0.7; 59% were male, and 93% were Caucasian.
These clinical trials evaluated TUDORZA PRESSAIR 400 mcg twice daily (636 patients) and placebo (640 patients). TUDORZA PRESSAIR 400 mcg resulted in statistically significantly greater bronchodilation as measured by change from baseline in morning pre-dose FEV1 at 12 weeks (the primary efficacy endpoint) compared to placebo in all three trials (Table 2).

|Treatment Arm||Baseline||Change from Baseline LS Mean (SE)||Treatment Difference LS Mean (95% CI)|
|Trial B (N=375)|
|Aclidinium 400 mcg||1.33||0.10 (0.01)||0.12 (0.08, 0.16)|
|Trial C (N=359)|
|Aclidinium 400 mcg||1.25||0.06 (0.02)||0.07 (0.03, 0.12)|
|Trial D* (N=542)|
|Aclidinium 400 mcg||1.51||0.06 (0.02)||0.11 (0.07, 0.14)|
|SE=standard error, and LS mean=least square mean. LS mean, and 95% confidence interval were obtained from an ANCOVA model with change from baseline in trough FEV1 as response, with treatment group and sex as factors and baseline trough FEV1 and age as covariates. |
* In the 6-month Trial D, placebo adjusted change from baseline in Trough FEV1 at 24 weeks was 0.13 (0.09, 0.17).
Serial spirometric evaluations were performed throughout daytime hours in a subset of patients in the three trials. The serial FEV1 values over 12 hours for one of the 3-month trials (Trial B) are displayed in Figure 2. Results for the other two placebo-controlled trials were similar to the results for Trial B. Improvement of lung function was maintained for 12 hours after a single dose and was consistent over the 3-or 6-month treatment period.
Figure 2: Mean FEV1 Over Time (prior to and after administration of study drug) on Day 1 and Week 12 in Subset of Patients Participating in the 12 hours Serial Spirometry Substudy for Trial B (a 3-month Placebo-Controlled Study)
Mean peak improvements in FEV1, for TUDORZA PRESSAIR relative to baseline were assessed in all patients in trials B, C and D after the first dose on day 1 and were similar at week 12. In Trials B and D but not in Trial C, patients treated with TUDORZA PRESSAIR used less daily rescue albuterol during the trial compared to patients treated with placebo.

Instructions for Use
(aclidinium bromide inhalation powder)
FOR ORAL INHALATION ONLY
Read this Instructions for Use before you start using TUDORZA PRESSAIR and each time you get a refill. There may be new information. This information does not take the place of talking to your doctor about your medical condition or your treatment.
Your TUDORZA PRESSAIR INHALER:
When you are ready to use TUDORZA PRESSAIR for the first time, remove the TUDORZA PRESSAIR inhaler from the pouch. To remove the inhaler from the pouch, tear along the “notch.” The pouch may then be discarded.
Look at the parts of the inhaler so you become familiar with them. (See Figure A)
Taking a dose from the TUDORZA PRESSAIR Inhaler requires you to press, release, and inhale. See the step-by-step instructions for using TUDORZA PRESSAIR below.
How to prepare and use your TUDORZA PRESSAIR Inhaler
Step 1. Remove the protective cap by lightly squeezing the arrows marked on each side of the cap and pulling outwards. (See Figure B)
- Look to see that nothing is blocking the mouthpiece.
Step 2. Hold the TUDORZA PRESSAIR inhaler with the mouthpiece facing you, but not inside your mouth. The green button should be facing straight up.(See Figure C)
Step 3. Before you put the inhaler into your mouth, press the green button all the way down.(See Figure D)
- Then release the green button.(See Figure E)
- Do not continue to hold the green button down.
Figure D and Figure E
Step 4. Stop and Check the Control Window to make sure your dose is ready for inhalation. Look to see if the colored control window has changed from red (See Figure F), to green (See Figure G)
- The green control window tells you that your medicine is ready for inhalation. (See Figure G)
- If the control window stays red (See Figure F), repeat the Press and Release actions in Step 3 until the control window is green.
Figure F and Figure G
Now the dose is ready to be inhaled.
Step 5. Before you put the inhaler into your mouth, breathe out completely. Do not breathe out into the inhaler.
- Put your lips tightly around the mouthpiece of the TUDORZA PRESSAIR inhaler. Breathe in quickly and deeply through your mouth. (See Figure H). This quick, deep breath makes sure that you get enough of the medication from the inhaler into your lungs.
- Breathe in until you hear a “click” sound. Keep breathing in, even after you have heard the inhaler “click” to be sure you get the full dose.
- Do not hold down the green button while you are breathing in. (See Figure H)
- Do not hold down the green button while you are breathing in. (See Figure I)
Figure H and Figure I
Step 6. Remove the TUDORZA PRESSAIR inhaler from your mouth and hold your breath for as long as is comfortable (See Figure J), then breathe out slowly through your nose.
Some people may taste the medicine during their inhalation. Do not take an extra dose even if you do not taste anything after inhaling.
Step 7. Stop and Check the Control Window. Make sure you have used your TUDORZA PRESSAIR inhaler correctly.
- Look at the control window to see if it has turned to red (See Figure K) from green (See Figure L). If the window is red you have inhaled your full dose of medicine correctly.
Figure K and Figure L
- If the colored control window is still green, repeat Step 5.
- If the window still does not change to red, you may have forgotten to release the green button before inhaling or may not have inhaled correctly. If that happens repeat Step 5 again.
- Make sure you have released the green button and take a quick and deep breath in through the mouthpiece.
- If you are unable to inhale correctly after several attempts, call your doctor.
Step 8. Once the window has turned red, place the protective cap back onto the inhaler by pressing it back onto the mouthpiece. (See Figure M)
Additional information about the safe and effective use of TUDORZA PRESSAIR inhaler
- The “click” sound and colored control window:
- The “click” that you hear while inhaling tells you that you are using the TUDORZA PRESSAIR inhaler correctly.
- When you use the inhaler correctly the colored control window changes from green to red.
- Each time you are ready to use the TUDORZA PRESSAIR inhaler again, you will need to make sure the inhaler is ready by pressing and releasing the green button as seen in Step 3. When you press and release the green button the colored control window will change from red to green.
Helpful Tips for Using Tudorza Pressair
The Tudorza Pressair inhaler comes ready-to-use with 3 steps for twice-daily dosing. Remember to Press, Release and Inhale every time you use Tudorza. PRESS the green button all the way down
RELEASE the green button completely

When should you get a new TUDORZA PRESSAIR inhaler?
- The TUDORZA PRESSAIR inhaler has a dose indicator to show you how many doses are left in your inhaler. Each TUDORZA PRESSAIR inhaler has 60 doses of medicine.
- When you start using the inhaler for the first time you will see the number 60 in the dose indicator.
- You will see the number of doses count down in the dose indicator as you use the inhaler. The dose indicator moves down slowly, displaying intervals of 10 (60, 50, 40, 30, 20, 10, 0).
- When a red band begins to appear in the dose indicator (See Figure N), this means you are nearing your last dose and should obtain a new PRESSAIR inhaler.
- You should discard the inhaler and start a new one when
- the marking “0” with the red background shows in the middle of the dose indicator (See Figure O), or
- the device locks out (See Figure P), or
- 45 days after you took the inhaler out of the sealed pouch, whichever comes first.
- If your TUDORZA PRESSAIR inhaler appears to be damaged or if you lose the cap, your inhaler should be replaced.
- You do not need to clean your TUDORZA PRESSAIR inhaler. If you wish to clean it, wipe the outside of the mouthpiece with a dry tissue or paper towel. Do not use water to clean your TUDORZA PRESSAIR inhaler, as this may damage your medicine.
Questions and Answers about your TUDORZA PRESSAIR Inhaler
|Do I need to take extra steps to prepare the inhaler before first use?||TUDORZA PRESSAIR comes preloaded with medicine and is ready to use. Remove the inhaler from the pouch and follow the step-by-step instructions for use.|
|How do I know if the PRESSAIR inhaler is ready to use before taking each dose?||The PRESSAIR inhaler is ready to use when the window on the front of the inhaler is green. (See Figure G) |
|What if the PRESSAIR inhaler window doesn't change from red to green?||Check that you have pressed the green button down fully and then completely let go of the button. (See Step 3) |
|How do I know that I used TUDORZA PRESSAIR correctly?||The PRESSAIR inhaler has helpful features to let you know that you are getting the full dose of medicine. |
|What if the TUDORZA PRESSAIR inhaler window does not change colors from green back to red after I inhale?||This means you have not inhaled the medicine correctly. Review the checklist below and try inhaling again. (See Step 7) |
|What if I do not see the dose counter move after I inhaled?||The PRESSAIR dose indicator counts down in intervals of 10. The numbers change slowly with each dose; you will not see a change in the number after each dose. (See Figure N) As long as you hear the click and see the window change from green to red, you have successfully inhaled the full dose.|
|Can the PRESSAIR inhaler release too much medicine or lose doses of medicine from the inhaler?||No. The PRESSAIR inhaler only releases 1 dose of medicine with each inhalation.
