Physiologically based pharmacokinetic modelling of intravenous and intranasal formulations of naloxone in healthy volunteers
This research is looking into a medicine called naloxone. Naloxone is very important because it can quickly reverse the life-threatening effects of an opioid overdose. The study aims to understand how the body processes naloxone when it's given in two different ways: directly into a vein through a drip (intravenous) and as a spray into the nose (intranasal). By carefully observing how quickly the medicine gets into the bloodstream, how long it stays there, and how it leaves the body, researchers can learn more about the best ways to use naloxone. This information helps doctors and scientists make sure the treatment is as effective and safe as possible for patients. This study involves healthy volunteers to understand the medicine without other health conditions complicating the results.
At a glance
What is this study about?
This research project is focused on understanding a crucial medicine called naloxone. You might have heard of naloxone because it's a very important treatment for reversing an opioid overdose. Opioids are strong pain medicines, and sometimes people can accidentally take too much, which can be very dangerous and even stop them breathing. Naloxone works quickly to block the effects of opioids and can save lives.
The study wants to compare two different ways of giving naloxone. One way is through a drip into a vein, which is called intravenous. The other way is by spraying it into the nose, which is called intranasal. Doctors and scientists want to clearly understand how the body handles naloxone when given in these different ways – for example, how quickly it gets into your system, how long it stays there, and how your body breaks it down and gets rid of it. This information is called 'pharmacokinetics'.
By carefully studying healthy volunteers, researchers can get a clear picture of how naloxone works without other diseases or conditions affecting the results. The goal is to build a better understanding of naloxone so that doctors can make the best choices about how to give it, ensuring it's as effective and safe as possible when it's needed most.
Key takeaways
- This study looks at a life-saving medicine called naloxone.
- It aims to understand how naloxone works when given by drip or nasal spray.
- Healthy volunteers are needed to help researchers understand the medicine better.
- The information gained will help doctors use naloxone more effectively.
- Participants will be closely monitored by a medical team.
Who may be eligible?
This study is looking for healthy people who are 18 years old or older. There is no upper age limit, meaning people of any adult age can take part.
Both men and women are welcome to participate in this study. The main requirement is that you are generally healthy and do not have any ongoing medical conditions that could affect how your body responds to the medicine being studied.
Specific details about what makes someone 'healthy enough' for this study, such as not taking certain medications or having specific health check results, would be discussed in more detail by the study team.
Could this study suit you?
Answer these quick questions to see if you may be eligible. This is a guide only — the research team makes the final call.
- Are you 18 years old or older?
- Are you generally healthy?
- Do you have any significant ongoing medical conditions?
- Are you currently taking any regular medications?
- Are you able to attend study visits as required?
What does participation involve?
If you take part in this study, you would likely need to visit the study clinic several times. During these visits, you would receive the naloxone medicine, either as a drip into your vein or as a nasal spray. The study team would closely monitor you for a period after receiving the medicine to see how your body reacts.
You would have blood samples taken regularly to measure how much naloxone is in your body over time. You might also have other check-ups like blood pressure readings and heart rate monitoring. The exact number of visits, how long each visit lasts, and the total duration you would be involved in the study would be explained in full detail by the research team.

Common questions
What is naloxone used for?
Naloxone is an important medicine used to quickly reverse the dangerous effects of an opioid overdose, such as difficulty breathing.
Why are you studying naloxone in healthy people?
By studying healthy people, researchers can get a clear understanding of how the body handles naloxone without other illnesses or medications affecting the results.
What's the difference between intravenous and intranasal?
Intravenous means the medicine is given through a drip into a vein, while intranasal means it's sprayed into the nose.
Will I get paid for taking part?
It's common for studies to cover travel expenses and sometimes offer payment for your time. This would be clearly explained by the study team.
Is this a new medicine?
No, naloxone has been used for many years. This study is about understanding how different ways of giving it work to improve its use.
