Original Abstract of the Article

Major Research Findings

Albuterol inhaler is a commonly used medication for asthma, and many studies have confirmed its bronchodilator effects. 29 compared the effects of albuterol's racemic mixture (RS-albuterol) with its active form, R-albuterol, and found that both showed comparable effects on bronchodilation, heart rate increase, and decreased potassium levels in blood. The therapeutic ratio was also comparable between the two forms.

9 compared the bronchodilator effects of albuterol and terbutaline and found no significant difference in bronchodilation or side effects. 4 compared albuterol and isoproterenol, another bronchodilator, and found no significant difference in bronchodilation or the speed at which the effect took place. However, isoproterenol is known to have cardiovascular side effects, therefore albuterol is preferred for use in pulmonary function testing.

Furthermore, 21 found that continuous administration of albuterol in patients with severe acute asthma led to significantly greater bronchodilation compared to intermittent administration. It also caused a more pronounced decrease in blood potassium levels. 10 found that high-dose albuterol nebulization in children with severe acute asthma resulted in significantly greater improvement in forced expiratory volume in 1 second, forced vital capacity, and wheeze score compared to low-dose administration, and led to a lower hospitalization rate. However, there was no significant difference in side effects.

34 suggested that levalbuterol (the R-enantiomer of albuterol) has a greater bronchodilator effect and lasts longer than albuterol in horses with recurrent airway obstruction.

33 conducted a meta-analysis of studies comparing levalbuterol and albuterol in patients with acute asthma. The analysis did not show significant differences in efficacy or safety between the two forms of albuterol.

Benefits and Risks

Benefits Summary

Albuterol inhaler is expected to improve breathing difficulties and wheezing symptoms in patients with asthma, as it is confirmed to have bronchodilator effects. 29 , 9 , 21 , 10 , 34 , 2 , 7 , 3 , 17 , 13 , 32 , 24 , 11

Risks Summary

Albuterol inhaler has reported side effects such as increased heart rate and decreased blood potassium levels. 29 , 21 , 8 , 28 , 6 , 5 , 19 , 26 , 30 It is suggested that long-term use of albuterol can lead to a decrease in the bronchodilator effect and an increase in airway hyperresponsiveness. 25 , 23

Comparing Research

Similarities in Research

Many studies have confirmed that albuterol inhaler has bronchodilator effects. Also, side effects such as increased heart rate and decreased potassium levels in blood have been reported in many studies.

Differences in Research

The effects and side effects of albuterol inhaler vary based on the dosage, administration method, and patient's condition, as shown in research results. 21 , 10 34 found that levalbuterol, the R-enantiomer of albuterol, showed promise in an animal model.

Consistency and Contradictions in Research

While there is consistency in the research regarding albuterol's effectiveness and side effects, 33 did not conclude that levalbuterol is more effective than albuterol.

Applying Research to Real-Life

Albuterol inhaler is expected to improve breathing difficulties and wheezing symptoms in patients with asthma. However, side effects such as increased heart rate and decreased potassium levels in blood can occur. Long-term use is also suggested to lead to a decrease in bronchodilation and an increase in airway hyperresponsiveness. Therefore, it is crucial to use albuterol inhaler under the guidance of a doctor and as prescribed.

Limitations of Current Research

Many studies only observed the effects and side effects of albuterol inhaler over short periods of time, thus there are still many unknowns about its long-term effects. The effects and side effects can also vary depending on the patient's individual body type, condition, and other medications they are taking.

Future Research Directions

Future research should focus on understanding the long-term effects of albuterol inhaler and its effects and side effects on individual patients in greater detail. Research is also needed to further clarify the efficacy and safety of levalbuterol.

Conclusion

Albuterol inhaler is an effective medication for treating asthma, but there is a possibility of side effects. Therefore, it is important to use albuterol inhaler under the guidance of a doctor and as prescribed. Further research is needed to better understand the long-term effects of albuterol inhaler and its effects and side effects on individual patients.

Asthma treatment

The development of tolerance to beta2-agonists in asthma therapy is a topic of debate. This study investigated whether chronic therapy with salmeterol resulted in tolerance to the bronchodilator effects of albuterol.

Dose-response evaluation of levalbuterol versus racemic albuterol in patients with asthma.

Author: HandleyD A, TinkelmanD, NoonanM, RollinsT E, SniderM E, CaronJ

Asthma treatment
Bronchodilation
Beta-mediated side effects

Levalbuterol, the single isomer version of albuterol, provides significant bronchodilatory activity and is well-tolerated. Lower doses of levalbuterol may be associated with fewer beta-mediated side effects.

The therapeutic ratio of R-albuterol is comparable with that of RS-albuterol in asthmatic patients.

Author: LötvallJ, PalmqvistM, ArvidssonP, MaloneyA, VentrescaG P, WardJ

Improves FEV1
Decreased potassium
Increased heart rate

The R-albuterol/RS-albuterol potency ratios for local (FEV(1)) and systemic effects (heart rate and K(+)) are similar, suggesting a comparable therapeutic ratio for R-albuterol and RS-albuterol in asthmatic subjects.

Bronchodilation
Asthma death
Asthma exacerbations
Cardiac failure
Cardiovascular death
Headache
Ischemic heart disease

Beneficial effects of albuterol therapy driven by heliox versus by oxygen in severe asthma exacerbation.

Author: LeeDavid Lin, HsuChien-Wei, LeeHuan, ChangHsueh-Wen, HuangYuh-Chin T

Improved asthma exacerbation

Two trials showed that heliox-driven albuterol therapy improved peak expiratory flow rate (PEF) and reduced emergency department (ED) stay in patients with severe asthma exacerbation. Older patients and those with lower pretreatment PEF benefited most.

Asthma treatment

Levalbuterol, the (R)-enantiomer of racemic albuterol, has bronchodilatory properties, while the (S)-enantiomer causes adverse effects. Levalbuterol improves pulmonary function in asthmatic patients with a longer duration of effect than albuterol.
