Comparative Bioavailability and Bioequivalence of Oxazepam 10 mg Orodispersible Tablets (Test) Versus Seresta® 10 mg Tablets (Reference): A Single-Dose, Open-Label, Randomized, Two-Sequence, Two-Treatment, Two-Period Crossover Study in Healthy Subjects
This study is looking at a new way to take oxazepam tablets. Oxazepam is a medicine used for anxiety. Researchers want to see if a new fast-dissolving 10mg tablet works in the body in the same way as the already approved 10mg Seresta tablet. This type of study, called a bioequivalence study, is important. It helps ensure that when a new version of a medication is made, it delivers the active ingredient into your bloodstream at the same speed and amount as the original. This means you can expect the same effect. Healthy adult volunteers will take part, receiving one tablet type at a time, to compare how their bodies handle each one. It’s part of the process to make sure new medicines are safe and effective.
At a glance
What is this study about?
Imagine you have two different brands of the same medicine – let's say, two different kinds of orange juice. Both contain orange juice, but one might be a new brand. This study is a bit like checking if the new brand of orange juice delivers the same amount of 'orange' to your system as the old one, and just as quickly. In medical terms, this study is comparing a new 10mg oxazepam tablet that dissolves in your mouth (called an 'orodispersible tablet') with an existing 10mg oxazepam tablet called Seresta.
Oxazepam is a medicine prescribed by doctors to help with anxiety. When a new version of an existing medicine is developed, even if it's just a different way it's taken (like dissolving in your mouth instead of being swallowed whole), regulators need to be sure it acts the same way in the body. This is called 'bioequivalence'. It means that the new tablet releases the medicine into your bloodstream at the same rate and extent as the original tablet. This is vital because it ensures the new version will have the same calming effect and safety profile as the original.
So, this study isn't looking into a new treatment for a specific illness. Instead, it's a necessary step in developing new medications. It's about making sure that different forms of the same medicine are equally effective and safe for patients. Volunteers who take part will help scientists gather this important information.
Key takeaways
- This study compares a new oxazepam tablet with an existing one.
- It aims to ensure new dissolving tablets work just as effectively as standard ones.
- Healthy adults, aged 18 and over, are needed as volunteers.
- Participants will have regular health checks and blood tests.
- You will receive both tablets at different times during the study.
- Your involvement helps ensure medicine safety and effectiveness for others.
Who may be eligible?
To join this study, you need to be a healthy adult, 18 years old or older. The study is open to both men and women. Because this study is checking how a medicine acts in healthy people, you won't be able to join if you have any serious or ongoing health problems.
This study is looking for healthy volunteers, not people with specific medical conditions. This means you should generally be well and not taking regular medication for long-term health issues. The research team will do medical checks to make sure you are suitable and fit enough to participate.
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, without any major ongoing medical conditions?
- Are you able to attend clinic visits as required?
- Are you willing to have blood samples taken?
- Are you not allergic to oxazepam or similar medications?
What does participation involve?
If you decide to take part, you'll visit the clinic regularly. This is a "crossover" study, which means you'll try both the new oxazepam tablet and the existing Seresta tablet at different times, with a break in between. During your visits, blood samples will be taken frequently to measure how much oxazepam is in your system. You'll also have standard health checks like measuring your heart rate, blood pressure, and having an electrocardiogram (ECG) to check your heart. You'll also be asked about any side effects you might experience. For the new dissolving tablet, you’ll be asked about how it tastes shortly after taking it. The specific number of visits and the total time you'll be involved will be explained by the study team, but generally, these types of studies involve overnight stays or multiple visits over a few weeks.

Common questions
What is oxazepam used for?
Oxazepam is a medication often prescribed by doctors to help treat anxiety.
Why is this study being done?
This study is being done to check if a new dissolving 10mg oxazepam tablet works the same way in the body as an existing 10mg tablet, ensuring it's equally effective and safe.
Do I need to have an illness to join?
No, this study is specifically looking for healthy adult volunteers, not people with a medical condition.
What does a 'crossover study' mean?
It means you will receive both types of tablets (the new one and the existing one) at different times during the study, allowing researchers to compare them directly in the same person.
Will I get paid for taking part?
Many clinical studies offer some payment or compensation for your time and travel, but you should ask the study team for details.
