RANDOMIZED, CROSSOVER, TWO-PERIOD, COMPARATIVE BIOAVAILABILITY STUDY OF TWO IBUPROFEN FORMULATIONS, AFTER A SINGLE ORAL DOSE OF 400 MG IN SOLUTION FORM TO HEALTHY SUBJECTS UNDER FASTING CONDITIONS
This research is looking at two forms of ibuprofen, a common painkiller. We want to find out how quickly and effectively each form is absorbed into the body when taken by healthy volunteers. Participants will take a single 400 mg dose of one ibuprofen type, then later, after a break, take a single 400 mg dose of the other. This helps us compare them directly. The study is for healthy adults and is an early stage of testing, focused on understanding how medicines behave in the body. The goal is to provide information that helps ensure new medicines are as effective as possible.
At a glance
What is this study about?
This study is designed to compare two different versions of ibuprofen, a very common medicine used to relieve pain and reduce fever. Imagine ibuprofen is a key; we want to see which lock (body) it opens more easily and efficiently. Researchers want to understand how well and how quickly each version of the medicine gets into the bloodstream after someone takes it.
To do this, healthy volunteers will take a single dose of one ibuprofen version. After some time, they'll switch and take a single dose of the other version. This is called a 'crossover' study, and it's a good way to directly compare two medicines because each person acts as their own control. The aim isn't to test if ibuprofen works for pain, as we already know it does, but rather to see if the new versions are absorbed in a similar way to existing, well-understood versions.
Understanding how a medicine is absorbed is really important. If a medicine isn't absorbed well, it might not work as effectively. This kind of research, called a 'bioavailability' study, helps ensure that new medicines, or new forms of existing medicines, deliver the right amount of drug to the body to do their job properly and safely. It's a crucial step in developing new medicines for everyone.
Key takeaways
- Compares two types of ibuprofen in healthy adults.
- Studies how well medicine is absorbed into the body.
- Involves single doses taken on two separate occasions.
- You'll need to be an adult (18+) and in good health.
- Helps develop better, more effective medicines.
Who may be eligible?
This study is looking for healthy volunteers. You'll need to be at least 18 years old to take part, but there isn't an upper age limit, meaning anyone over 18 can be considered.
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?
- Can you follow specific instructions like fasting?
- Are you able to attend multiple study visits?
What does participation involve?
If you join this study, you would visit the study clinic on two separate occasions. On each visit, you would take a single dose of an ibuprofen solution after not eating for a while (fasting). After taking the medicine, you'd have blood samples taken regularly over several hours to see how the ibuprofen is absorbed by your body. There would be a 'washout' period between these two visits – a break where you don't take any study medication – to make sure the first dose is completely out of your system before you take the second dose. The total duration of your participation, including the time between visits, would vary but typically these types of studies involve two treatment days spread over a couple of weeks.

Common questions
What is 'bioavailability'?
It means how much of a medicine actually gets into your bloodstream and is available to do its job.
Do I need to be ill to join?
No, this study is specifically looking for healthy volunteers.
Will I know which ibuprofen I'm taking?
You will take both versions, but the order might be random, and you won't necessarily know which one you're taking at any given time.
What does 'fasting conditions' mean?
It means you won't be allowed to eat or drink anything (except water) for a certain period before and during part of the study day.
Will I get paid for taking part?
Often, studies like this offer some payment for your time and inconvenience, but you'd need to ask the study team about specifics.
