Beta-Agonist Inhalers for Healthy Subjects
What You Need to Know Before You Apply
What is the purpose of this trial?
This trial examines how asthma inhalers affect the blood vessels and heart in healthy young adults. The researchers aim to determine if long-term use of these inhalers impacts the cardiovascular system. Participants will use an inhaler for four weeks and undergo various tests, including lung function assessments and ultrasound imaging of their arm artery. The trial compares two inhalers, Ventolin (salbutamol) and Symbicort (budesonide/formoterol), with a placebo to identify any differences. Healthy individuals without a history of heart or lung disease may be suitable for this study. As a Phase 1 trial, this research focuses on understanding how the treatment works in people, offering participants an opportunity to contribute to foundational medical knowledge.
Will I have to stop taking my current medications?
Yes, you will need to stop taking certain medications to participate in this trial. The trial excludes participants who are using specific medications like monoamine oxidase inhibitors, tricyclic antidepressants, beta-blockers, and several others.
Is there any evidence suggesting that this trial's treatments are likely to be safe?
Research shows that both budesonide-formoterol and salbutamol inhalers are generally well-tolerated by most people. Budesonide-formoterol is often used for asthma and chronic obstructive pulmonary disease (COPD). Studies have confirmed its safety, with no new safety concerns in patients with mild asthma.
Salbutamol, also known as Ventolin, has been tested in various trials with over 248 participants. It is generally considered safe but can cause some side effects, such as palpitations (a feeling of a rapid heartbeat) or a fast heart rate.
Both treatments have long been used to help with breathing problems and are FDA-approved for these uses, indicating a strong safety record for these conditions. However, since this trial is in an early phase, it is specifically designed to carefully test safety in healthy individuals.12345Why are researchers excited about this trial's treatments?
Researchers are excited about these treatments because they explore different ways to use inhalers, even for those without respiratory issues. Budesonide/formoterol is unique as it combines a steroid with a long-acting beta-agonist, potentially providing prolonged relief and reducing inflammation. Salbutamol, another focus, is a fast-acting bronchodilator that quickly opens airways, which could be beneficial even for short-term usage in healthy individuals. This trial helps understand how these treatments might enhance respiratory function or be used in new ways beyond traditional asthma or COPD treatment.
What evidence suggests that this trial's treatments could be effective for blood vessel health?
This trial will compare the effects of different inhalers on healthy individuals. Research has shown that inhalers like Symbicort, which contain budesonide and formoterol, can improve lung function in people with asthma over time. One study found that 97% of patients felt relief within minutes of using it, indicating significant benefits for lung performance. In this trial, some participants will receive budesonide-formoterol.
Another group will receive salbutamol, often used for quick asthma relief. Studies have found that salbutamol can increase heart rate and blood pressure in healthy people. However, it did not enhance exercise performance in those without asthma, suggesting it may not improve lung function for non-asthmatic individuals.
A placebo group will also be included to compare the effects of these treatments.678910Who Is on the Research Team?

Are You a Good Fit for This Trial?
This trial is for healthy individuals aged 18-40 without heart or lung diseases. Participants should not be using medical inhalers, have abnormal exercise test results, pre-existing cardiac conditions, or be pregnant/lactating. Women must use contraception if they can bear children.Exclusion Criteria
