What Is Breztri Aerosphere?

Breztri Aerosphere (budesonide, glycopyrrolate, and formoterol) is a prescription medication that is used as a maintenance treatment for individuals with chronic obstructive pulmonary disease (COPD).

Breztri Aerosphere is unique in the fact that it is a combination medication with three different components to treat COPD. To understand how this medication works, it is essential to understand the individual active ingredients.

Budesonide belongs to a drug class known as inhaled corticosteroids (ICS). A person with COPD receives a limited amount of air due to chronic inflammation of the airways. Budesonide and other ICS drugs work by reducing the inflammation. This class of medications acts by limiting cells and chemicals typically released during an inflammatory response.

Glycopyrrolate is a long-acting antimuscarinic agent. Glycopyrrolate acts on multiple receptors in the body, but its effect primarily blocks M3 receptors, which are a type of muscarinic receptor. Under normal conditions, activation of the M3 receptor results in the airways tightening, making it more difficult to breathe. Inhibiting the M3 receptor helps relax the airways around the lungs, ultimately allowing for more air to pass through.

Formoterol is a long-acting selective beta-2 adrenergic agonist (LABA) that quickly takes effect. It sticks to beta-2 adrenergic receptors throughout the body and cause the muscles in the airways to relax, allowing for more air to pass through.

Breztri Aerosphere is only available by prescription. It is inhaled via a pressured metered dose inhaler.

What Is Breztri Aerosphere Used For?

The Food and Drug Administration (FDA) approved Breztri Aerosphere for the maintenance treatment of individuals with chronic obstructive pulmonary disease (COPD). COPD is a chronic lung condition that includes chronic bronchitis, emphysema, or both.

It is important to note it is used for maintenance only. It should NOT be used to relieve acute symptoms of COPD; you should use a rescue inhaler for the intense flare-ups of shortness of breath.

How to Take Breztri Aerosphere

Breztri Aerosphere is an inhaler for oral inhalation only. You should always follow directions given to you by your healthcare provider on how to take it, but generally, it is prescribed to take two inhalations twice daily.

Before your first use, you must remember to prime the inhaler to make sure you get the appropriate dose.

To prime the inhaler:

  • Remove the cap from the inhaler's mouthpiece.
  • Hold the inhaler in an upright position away from your face and shake it well.
  • Hold the inhaler with your thumb supporting the base and your first two fingers on the dose indicator at the top.
  • Press down on the dose indicator until the canister no longer moves to release a puff from the inhaler.
  • Shake and press on the dose indicator three more times.

After priming it four times, your inhaler is ready for use. If you drop your inhaler or don't use it for more than seven days, you must reprime it before using it again. To reprime your inhaler, shake it well and press the dose indicator on top twice to release two puffs away from your face.

To use your inhaler:

  • Shake the inhaler well before each use.
  • Remove the cap from the mouthpiece.
  • Hold the inhaler with the mouthpiece pointing toward you and exhale through your mouth completely.
  • Close your lips around the mouthpiece and tilt your head back, keeping your tongue below the mouthpiece. While breathing in deeply and slowly, press down on the dose indicator until the canister stops moving down to release one puff from the inhaler. Then, stop pressing the dose indicator.
  • When you have finished breathing in, remove the mouthpiece from your mouth.
  • Hold your breath as long as you comfortably can, up to 10 seconds. Breathe out slowly and repeat the steps above to take your second dose from the inhaler.
  • Replace the cap over the mouthpiece immediately after use.
  • Rinse your mouth with water (do not swallow) to remove excess medicine, as budesonide (a steroid) can cause thrush.

It is recommended to clean the inhaler at least every seven days. You will need to prime it again after cleaning. To clean, remove the canister from the actuator, and run warm water through the actuator for approximately 30 seconds. Then, turn the actuator upside down and run warm water through it again for another 30 seconds, and allow it to air dry completely.


Store Breztri Aerosphere in a cool, dry place in its original package. Only open the foil pouch when you are ready to use it. Throw the medication away three months after opening it (for the 120-inhalation canister) or three weeks after opening the foil pouch (for the 28-inhalation canister), or when the counter reads zero, whichever comes first.

Medications should be kept away from hot or humid areas, such as your kitchen or bathroom. You should also keep Breztri Aerosphere away from bright light exposure. These environments can impact how well medications work. It is also essential to ensure this medication is kept away from children and pets to avoid accidental consumption.

Generally, it is best to contact your pharmacist at least a week before you run out of the medication to put in a refill request.

How Long Does Breztri Aerosphere Take to Work?

Breztri Aerosphere has several active ingredients, but formoterol has the quickest effect. Formoterol is expected to work within one to three minutes and has a sustained impact for upwards of 12 hours. Breztri Aerosphere improved lung function in clinical trials when used for 24 to 52 weeks.

What Are Reasons I Shouldn’t Take Breztri Aerosphere?

This medication is not recommended for children, as there are no studies related to safety or how well the drug works in this age group. People with asthma should also not be using this medication due to the same lack of information. You should NOT take Breztri Aerosphere if you have ever experienced a severe allergic reaction to its ingredients: budesonide, glycopyrrolate, or formoterol.

What Other Medications Interact With Breztri Aerosphere?

To know which medications interact with Breztri, it is important to understand how it is converted in the body. The ingredient budesonide is eliminated from the body by a class of proteins known as cytochrome P450 isoenzyme 3A4 (CYP3A4). Since it is broken down by this protein, drugs that decrease the rate at which these proteins work (known as inhibitors) can increase the amount of budesonide in the body.

Some common inhibitors of CYP3A4 are listed below:

Breztri Aerosphere contains a beta-2 agonist (formoterol). Therefore, other drugs that affect this receptor should be used with caution. Medications that also act on beta-2 receptors include:

  • Adrenaclick, Adrenalin, Auvi-Q, EpiPen, Primatene Mist, Symjepi (epinephrine)
  • Akovaz, Corphedra, Rezipres (ephedrine)
  • Dobutamine
  • Levophed (norepinephrine)

Drugs that work against beta-2 receptors (known as beta-blockers) may decrease how well Breztri Aerosphere works and vice versa. If a beta-blocker is needed, your healthcare provider may select one that is more specific to the heart. However, they should still be used with caution.

Examples of beta-blockers include:

Other medications that should be used with caution if taken with Breztri Aerosphere include:

What Medications Are Similar?

Trelegy (fluticasone, umeclidinium, and vilanterol) is another medication that uses three ingredients within a single inhaler.

There are also other combination inhalers with two components, such as:

  • Dulera (mometasone and formoterol)
  • Advair Diskus, Advair HFA, AirDuo Digihaler, Airduo Respiclick (fluticasone and salmeterol)
  • Symbicort (budesonide and formoterol)
  • Breo Ellipta (fluticasone and vilanterol) 

This list is a list of drugs also prescribed for the targeted condition(s). It is NOT a list of medicines recommended to take with Breztri Aerosphere. You should not take these drugs together. Ask your pharmacist or a healthcare provider if you have questions.
