Albuterol for Secondhand Smoke Exposure
What You Need to Know Before You Apply
What is the purpose of this trial?
This trial aims to determine if albuterol, a medication often used for asthma, can improve lung function in flight attendants exposed to secondhand smoke before smoking was banned on planes. The researchers seek to find out if albuterol can alleviate breathing problems in those who have never smoked but still show signs of lung issues. Eligible participants should be former flight attendants who worked in smoky airplane cabins for over a year and have never smoked more than 100 cigarettes in their lifetime. Participants will receive both albuterol and a placebo (a non-active substance) to compare effects. As a Phase 4 trial, this study involves an FDA-approved treatment and aims to understand how albuterol benefits more patients.
Will I have to stop taking my current medications?
The trial information does not specify whether you need to stop taking your current medications. It's best to discuss this with the trial coordinators or your doctor.
What is the safety track record for Albuterol?
Research shows that albuterol, the treatment under study, has been used for many years to help with breathing problems and is generally considered safe. Some studies indicate it can cause minor side effects, but these are usually not serious. Albuterol improves airflow and breathing, especially in people exposed to secondhand smoke. Since this trial is in Phase 4, albuterol has already received FDA approval for other uses, indicating that its safety is well understood.12345
Why are researchers enthusiastic about this study treatment?
Most treatments for issues related to secondhand smoke exposure focus on minimizing exposure or managing symptoms with general medications. However, researchers are exploring albuterol, typically used for asthma, as a direct treatment option. Albuterol is unique because it acts as a bronchodilator, helping to open up airways and improve breathing by relaxing the muscles in the lungs. This mechanism could offer a more targeted approach to alleviate breathing difficulties caused by secondhand smoke. Researchers are excited about its potential to provide rapid relief compared to standard symptom management options, which often don't address the specific respiratory effects of secondhand smoke.
What evidence suggests that albuterol might be an effective treatment for secondhand smoke exposure?
Research has shown that albuterol can aid individuals with breathing problems caused by secondhand smoke. In studies, albuterol improved breathing and exercise capacity in those with lung issues from secondhand smoke, even without severe lung disease. This trial will assess albuterol's effectiveness in enhancing airflow and reducing trapped air in the lungs. Participants will receive albuterol in one phase and a placebo in another, enabling researchers to compare the effects. Albuterol may help open the airways, making breathing easier. Thus, even without serious lung damage, albuterol could improve breathing and activity levels for those exposed to secondhand smoke.12367

Are You a Good Fit for This Trial?
This trial is for never-smoking flight attendants exposed to secondhand smoke for over a year before the smoking ban on planes. They should have airflow limitations but not be diagnosed with overt COPD, and can't have used more than 100 cigarettes or joints in their lifetime. Participants must be able to exercise and not suffer from obesity (BMI >30), active heart disease, severe autoimmune diseases, or other lung-affecting conditions.Inclusion Criteria

What Are the Treatments Tested in This Trial?
Interventions
- Albuterol
- Placebo
Trial Overview
The study tests if Albuterol, a bronchodilator, can improve lung function in these individuals by comparing it with a placebo. It aims to confirm obstructive lung disease presence due to chronic SHS exposure and explore treatment options.

Experimental Treatment
Participants will be placed on the placebo treatment after the completion of the baseline screening visit. They will use placebo for 4 weeks prior to their scheduled second visit during which they will undergo testing. Subsequently, and after a minimum washout period of 2 weeks, they will be placed on the albuterol treatment (2 puffs twice a day, equivalent to 360 mcg per day) for 4 weeks prior to their scheduled third visit, after which they will come back to undergo testing.
