A bioavailability study of epinephrine following a single dose of emergency response auto-injector in comparison to epinephrine injection into muscle via syringe in healthy adults.
This research is looking at how efficiently adrenaline, a crucial medicine for severe allergic reactions often called anaphylaxis, is absorbed into the body. Specifically, it compares two ways of giving this medicine: using an auto-injector (like those prescribed for emergencies) versus a standard injection with a syringe. We want to see if the auto-injector delivers the medicine into the bloodstream as effectively as a manual injection. This is an early-stage study involving healthy adult volunteers. The goal is to ensure that when someone has a life-threatening allergic reaction, the auto-injector they use works as well as possible to get the medicine where it's needed quickly.
At a glance
What is this study about?
Imagine someone is having a very severe allergic reaction, which doctors call anaphylaxis. This can be really serious and needs urgent treatment. One of the main medicines given for this is called adrenaline, or epinephrine. It's often given using a special device called an auto-injector, which is designed to be easy to use in an emergency.
This study is trying to understand how well adrenaline from one of these auto-injectors gets into the body compared to when it's given the old-fashioned way, with a needle and syringe. They want to make sure that the auto-injectors, which are so important for people with allergies, are working as effectively as possible to deliver this life-saving medicine.
By carefully comparing these two methods in healthy adults, researchers can gather important information. This helps ensure that when someone experiences a severe allergic reaction, the medicine they rely on is delivered in the most effective way, helping them recover quickly and safely. It's about making sure emergency treatments are as good as they can be.
Key takeaways
- This study compares two ways of giving adrenaline: auto-injector vs. syringe.
- It aims to understand how well adrenaline is absorbed into the body.
- Only healthy adults aged 18 and over can participate.
- Participation involves receiving adrenaline and giving blood samples.
- Your involvement helps improve emergency care for severe allergies.
- You can leave the study at any time.
Who may be eligible?
This study is looking for healthy adults to take part. This means you should generally be in good health and not have any serious ongoing medical conditions.
You need to be 18 years old or older to join this study. There is no upper age limit, as long as you are considered healthy by the study doctors.
Both men and women are welcome to participate. The study team will check your full medical history and carry out some tests to make sure it's safe and suitable for you to take part.
- Are you 18 years old or older?
- Are you generally healthy with no major ongoing medical conditions?
- Are you able to attend study visits at a clinic?
- Are you comfortable receiving injections and having blood samples taken?
This is a guide only — the research team will confirm whether you can take part.
What does participation involve?
If you decide to take part, you'll visit a study clinic. During your visits, you will receive a single dose of adrenaline. For some visits, this will be given using an auto-injector, and for others, it will be given with a standard needle and syringe. After you receive the medicine, the doctors will regularly take small blood samples to check how much adrenaline is in your body and how quickly it's absorbed. They will also monitor your health closely, checking things like your heart rate and blood pressure. The study will involve a few visits over a short period, as the main focus is on what happens right after the medicine is given. The total duration of your participation, including all follow-up, will be explained in detail.

Common questions
What is adrenaline (epinephrine)?
Adrenaline is a natural hormone and a medicine used to treat severe allergic reactions, which can be life-threatening.
What is an auto-injector?
An auto-injector is a device that automatically injects a pre-measured dose of medicine, often used for emergencies like severe allergic reactions.
Do I need to have allergies to join this study?
No, this study is for healthy adults, so you do not need to have allergies to take part.
Will I receive an allergic reaction treatment?
You'll receive adrenaline, which is a treatment for allergic reactions, but it's given to healthy people in this study to see how the body handles it.
How long will each study visit last?
Each visit might last several hours, as blood samples need to be taken at different times after the adrenaline is given.
