What to Know About Mixture Bronchial asthma Inhalers
Mixture bronchial asthma inhalers are used for long-term management of bronchial asthma signs and remedy and prevention of bronchial asthma assaults. They mix totally different inhaled medicines—a corticosteroid, a long-acting beta-agonist (LABA), a short-acting beta-agonist (SABA), or a long-acting muscarinic antagonist (LAMA).
Corticosteroids management irritation, whereas LABAs, SABAs, and LAMAs are bronchodilators that widen and open constricted airways to permit for the free move of air. When used collectively, these medicines can ease the hyperresponsiveness of airways and assist to stave off an bronchial asthma assault.

Sorts
There are seven mixture inhalers authorised by the U.S. Meals and Drug Administration (FDA) for treating bronchial asthma:
- Advair HFA, a mix of the steroid fluticasone and the LABA salmeterol (authorised in 2000)
- Advair Diskus, a mix of the steroid fluticasone and the LABA salmeterol in dry powder type (authorised in 2000)
- Airsupra, a mix of the steroid budesonide and SABA albuterol (authorised in 2023)
- Breo Ellipta, a mix of the steroid fluticasone and the LABA vilanterol (authorised in 2015)
- Dulera, a mix of the steroid mometasone and the LABA formoterol (authorised in 2010)
- Symbicort, a mix of the steroid budesonide and the LABA formoterol (authorised in 2006)
- Trelegy Ellipta, a mix of the steroid fluticasone, the LAMA umeclidinium, and the LABA vilanterol (authorised in 2017)
Generic types of Advair, identified by the model names AirDuo Respiclick, Wixela Inhub, and others, additionally can be found. Symbicort generics (together with the branded generic Breyna, authorised in 2022) are additionally generally bought as a budesonide/formoterol inhaler.
Makes use of
Mixture inhalers are used to regulate bronchial asthma signs and beat back bronchial asthma assaults. Every targets a selected facet of the physiological occasions that comprise an bronchial asthma assault:
- Corticosteroids, also referred to as steroids, mimic the hormone cortisol, which the physique naturally produces to regulate irritation. When used every day, corticosteroids assist management the irritation that contributes to airway hyperresponsiveness.
- LABAs, LAMAs, and SABAs are labeled as bronchodilators, which means they assist open (dilate) the airways of the lungs—i.e., the bronchi and bronchioles. Though LABAs and LAMAs mechanism of motion are just like rescue inhalers (SABAs), they’re longer-lasting and, when taken every day, successfully stop bronchospasms and airways’ narrowing.
Different Authorized and Off-Label Makes use of
Symbicort and Breo are also authorised for the every day remedy of persistent obstructive pulmonary illness (COPD). Advair Diskus, the dry powder type of the drug, is authorised for COPD as properly, though its aerosolized type, Advair HFA, isn’t.
Research have proven that salmeterol, the LABA utilized in Advair HFA, will increase the chance of pneumonia in individuals with COPD. Although Advair Diskus additionally comprises salmeterol, the dose is way smaller and is taken into account safer for ongoing use.
Some healthcare suppliers prescribe Dulera off-label to individuals with COPD, though its security and effectiveness for this goal haven’t but been established.
Earlier than Taking
You’re a candidate for a mix bronchial asthma inhaler if a rescue inhaler alone fails to regulate your bronchial asthma, which means you:
- Should use your rescue inhaler greater than twice per week
- Awaken at evening with bronchial asthma signs greater than twice a month
- Need to refill your rescue inhaler prescription greater than twice per week
Initially, inhaled corticosteroids had been the primary medication used as controller medicines if a rescue inhaler failed to supply sufficient management of bronchial asthma signs. Right this moment, as a substitute of ready so as to add a LABA to the remedy plan, many well being authorities—together with the International Initiative for Bronchial asthma (GINA)—endorse the mixed use of an inhaled corticosteroid and an inhaled LABA from the beginning.
That’s not to recommend a mix inhaler is a one-size-fits-all-solution. A 2015 examine within the Annals of the American Thoracic Society argued that inhaled steroids had been simply as efficient in controlling bronchial asthma signs as mixed steroid/LABA remedy and allowed for changes in doses when wanted.
Different research contend that, due to their comfort, individuals are extra possible to make use of them as prescribed, successfully enhancing well being outcomes in individuals with bronchial asthma. Furthermore, mixture inhalers require a smaller dose of steroids to attain the identical advantages in management as single steroid inhalers.
A 2013 evaluation within the Cochrane Database of Systematic Opinions concluded that individuals who used mixture inhalers had been much less prone to be hospitalized or want emergency room visits than those that used two totally different inhalers and had been much less prone to want stronger oral steroids sooner or later.
Precautions and Contrainidications
The one absolute contraindication for using a mix inhaler is a identified allergy to any energetic or inactive ingredient used within the inhaler. This contains an allergy to take advantage of, as milk powder is a central inactive ingredient in each Advair Diskus and Breo Ellipta.
LABAs are identified to have an effect on blood stress, blood sugar, coronary heart charge, thyroid hormone manufacturing, and the firing of mind cells. These results are tempered considerably by inhaled corticosteroids, permitting LABAs to be delivered at smaller doses.
There is also proof the long-term use of inhaled corticosteroids can have an effect on the eyes in addition to impair the physique’s means to struggle infections.
Due to these issues, mixture bronchial asthma inhalers ought to be used with warning in individuals with the next well being circumstances:
Folks with any of those circumstances ought to be routinely monitored to establish modifications of their well being standing whereas on mixture inhalers. In some circumstances, remedy could have to be stopped if signs worsen.
All mixture bronchial asthma inhalers ought to be used with warning throughout being pregnant, as animal research have advised a possible for fetal hurt, however no well-controlled research in people can be found.
Though there is no such thing as a proof of an elevated threat of start defects in being pregnant registries, it’s nonetheless essential to talk together with your healthcare supplier to weigh the advantages and dangers of remedy if you’re pregnant, breastfeeding, or planning to get pregnant.
Dosage
The mix bronchial asthma inhalers at present authorised by the FDA will be categorized by their supply system:
- Advair HFA, Airsupra, Dulera, and Symbicort are meter-dose inhalers (MDIs) that ship medicines utilizing an aerosolized propellent.
- Advair Diskus. Breo Ellipta, and Trelegy Ellipta are dry powder inhalers (DPIs) that ship a dose of the treatment in powder type that you just inhale by means of the mouthpiece.
The really helpful dose can range by age. As a normal rule, smaller doses are prescribed when first beginning remedy and elevated provided that the drug fails to supply sufficient management of signs.

Nonetheless, younger kids ought to be monitored because the long-term use of a mix inhaler could impair development. The dangers seem best amongst toddlers with extreme persistent bronchial asthma.
There are a variety of frequent medication and drug lessons identified to work together with mixture bronchial asthma inhalers.
Corticosteroids and LABAs are each metabolized by a liver enzyme known as cytochrome P450 (CYP450) and might work together with different medication that use the identical enzyme for metabolization. This competitors can sluggish the speed at which a drug is cleared from the physique. This will likely both enhance the focus of a drug (together with its negative effects) or lower the focus of a drug (and scale back its efficacy).
Among the many medication of best concern are:
- Antibiotics like clarithromycin, telithromycin, and troleandomycin
- Antifungals like ketoconazole, itraconazole, and voriconazole
- Atypical antidepressants like Serzone (nefazodone)
- HIV medication like Kaletra (ritonavir/lopinavir), Crixivan (indinavir), and Invirase (saquinavir)
LABAs on their very own can work together with 4 lessons of medication in numerous methods. These embrace:
- Beta-blockers like Lopressor (metoprolol) or Sectral (acebutolol) could block the impact of the mix inhaler and even set off bronchospasms.
- Monoamine oxidase inhibitor (MAOI) antidepressants like Parnate (tranylcypromine) could set off coronary heart rhythm issues.
- Non-potassium-sparing diuretics like hydrochlorothiazide could result in low potassium (hypokalemia) and set off cardiac irregularities.

The advisement was primarily based on research through which 13 deaths had been reported amongst 13,176 LABA customers over a 28-week examine interval.
On December 20, 2017, the FDA reversed the order when it was proven that the chance of dying occurred when LABAs had been used on their very own (in monotherapy). Present analysis has proven that the mixed use of a LABA and corticosteroid poses no such hurt.
Though the black field warning has been stripped from the packaging of mixture bronchial asthma inhalers, it stays on all single-ingredient LABA medicines.
