Randomized, crossover, two-period, comparative bioavailability study of two ibuprofen (arginate) formulations, administered as solutions in single oral dose of 400 mg to healthy subjects under fasting conditions.
This study is comparing two different liquid forms of a painkiller called ibuprofen arginate. We want to understand how quickly and effectively the ibuprofen gets absorbed into the body from each type of liquid. This is important to make sure that new versions of medicines work just as well as existing ones. Healthy adults will be taking part, and they will receive a single dose of 400 mg of each formulation at different times. Participants will be asked to fast (not eat) before taking the medicine. This type of study mainly focuses on understanding how the drug behaves in the body. It helps ensure that any new medicine is safe and effective when compared to others. The aim is to help develop reliable pain relief options for the future.
At a glance
What is this study about?
This study is looking into a common painkiller called ibuprofen arginate, which is a specific type of ibuprofen that often works quickly. We are comparing two different liquid versions of this medicine. The main goal is to see how these two liquids are absorbed and used by the body. Think of it like comparing two different brands of a fizzy drink – they both contain the same main ingredient, but we want to check if your body uses them in exactly the same way.
This kind of research is important because when a company makes a new version of a medicine, especially a liquid form, they need to show that it works just as well and is absorbed similarly to existing, approved versions. This helps ensure that patients always get a consistent and effective treatment, no matter which version of the medicine they are given. It’s about making sure future medicines are just as reliable for you.
By understanding how these different liquid forms behave in the body, scientists can make sure that any new ibuprofen product will be absorbed correctly and deliver the right amount of medication to treat pain effectively. This particular study is an early-stage investigation, focusing purely on how the medicine works inside healthy individuals, rather than testing its effects on a specific illness.
Key takeaways
- This study compares two different liquid forms of ibuprofen arginate.
- It aims to see how well and how quickly the body absorbs each medicine.
- Only healthy adults, aged 18 and over, can participate.
- Participants will need to fast before taking the medicine.
- You'll get both liquid forms over different visits.
- The study helps ensure new medicines are safe and work effectively.
Who may be eligible?
This study is looking for healthy adults to take part. This means we're looking for people who generally feel well and don't have any major ongoing health problems.
You would need to be at least 18 years old to be considered for this study. There is no upper age limit, meaning older adults are welcome to participate as long as they are in good general health.
Both men and women are invited to take part in this study. The most important thing is that you are healthy, as confirmed by medical checks, and you meet the age requirement.
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.
- Am I at least 18 years old?
- Do I consider myself generally healthy?
- Do I have any major ongoing medical conditions?
- Am I able to follow instructions about fasting?
- Am I able to attend multiple study visits?
What does participation involve?
If you decide to take part, you will be given a single dose of one liquid ibuprofen formulation on one occasion, and then a single dose of the other liquid formulation on a separate occasion. This is a 'crossover' study, meaning you will receive both treatments at different times. Before each medicine dose, you will need to come to the study centre and will be asked to fast, which means not eating anything for a certain period, usually overnight. During your visits, medical staff will take some blood samples at different times to measure how the ibuprofen is absorbed into your body. They will also keep a close eye on you to make sure you are well and to check for any reactions. This study involves a few visits to the clinic, usually spaced out by a 'washout' period where you don't take any study medication. The total time you'd be involved in the study, including all visits and follow-ups, would be explained to you in detail.

Common questions
What is ibuprofen arginate?
Ibuprofen arginate is a type of ibuprofen that is designed to be absorbed more quickly by your body, often leading to faster pain relief.
What does 'fasting' mean for this study?
Fasting means you will be asked not to eat or drink anything (except plain water) for a specific number of hours before taking the study medicine, usually overnight.
Will I know which liquid ibuprofen I'm getting?
In a 'crossover' study like this, you will receive both liquid forms of ibuprofen over different visits. You might not know which one you're getting on a particular visit, and sometimes the staff might not know either, to keep the comparison fair.
What does 'healthy volunteers' mean?
It means the study is looking for people who are generally well, without any long-term medical conditions that could affect how their body handles the medicine being tested.
Will I get paid for taking part?
Most studies for healthy volunteers offer some reimbursement for your time, travel, and inconvenience. This would be clearly explained to you before you agree to take part.
