Bioequivalence of Lisdexamfetamine dimesylate 70 mg Capsules in Healthy Participants Under Fasting Conditions.
This research study is looking at a medicine called lisdexamfetamine dimesylate 70 mg, which is usually used for certain conditions. However, this study isn't looking at treating an illness. Instead, it's making sure that a new version of this medicine works in exactly the same way as an older, established version. This is important to ensure that new medicines are just as safe and effective. Healthy volunteers will take the medicine after not eating for a while (fasting). Researchers will then measure how the medicine is absorbed and used by the body. This helps us understand if the new version is 'bioequivalent,' meaning it behaves the same way in the body.
At a glance
What is this study about?
This study is all about a medicine called lisdexamfetamine dimesylate, specifically the 70 mg capsule. You might recognise this medicine as it's sometimes used for conditions like ADHD (Attention-Deficit/Hyperactivity Disorder). However, it's very important to understand that this study is not about treating ADHD or any other illness. Instead, it's a very common type of study that medicine companies do when they're developing new versions of medicines that are already available.
The main goal here is to find out if a new version of this lisdexamfetamine dimesylate 70 mg capsule works in exactly the same way as the original or well-known version. Think of it like comparing two different brands of a popular painkiller; you want to make sure the newer brand still gives you the same relief and is absorbed by your body in the same way. This kind of study helps make sure that whenever a new version of a medicine comes out, it will be just as effective and safe as the one people are used to.
To check this, healthy people will take the medicine after a period of not eating, also known as fasting. This helps researchers see how the medicine is absorbed without food affecting it. By carefully measuring how much of the medicine gets into the bloodstream and how quickly, they can tell if the new version is 'bioequivalent.' This means it performs just like the established version. This is a vital step in bringing new medicines to people safely and reliably.
Key takeaways
- This study compares a new version of a medicine called lisdexamfetamine dimesylate 70 mg to an existing one.
- It's for healthy adults, not people with a specific illness.
- Participants will take the medicine after fasting (not eating beforehand).
- The goal is to ensure the new version works exactly the same in the body (is 'bioequivalent').
- It involves several visits, mostly for blood tests.
- You'll likely be compensated for your time and participation.
Who may be eligible?
This study is looking for volunteers who are healthy adults. This means you shouldn't have any serious ongoing medical conditions or take regular medications that could affect the study results. It's also suitable for both men and women.
You need to be at least 18 years old to take part. There isn't an upper age limit mentioned, but generally, studies like this look for adults who are in good general health.
Because this study isn't about treating an illness, they are specifically looking for people who are generally healthy.
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 with no ongoing serious medical conditions?
- Are you willing to fast before taking the study medicine?
- Are you able to attend clinic visits for tests, including blood draws?
- Are you comfortable with taking a study medicine for research purposes?
What does participation involve?
If you decide to take part, you would usually visit the study clinic several times. On these visits, you would typically receive the medicine after not eating (fasting) for a certain number of hours, usually overnight. Over the next few hours, healthcare staff would take regular blood samples to see how the medicine is being processed by your body. You might also have your blood pressure and heart rate checked. There will likely be a follow-up visit or call after your last dose to check on your well-being. The total length of your involvement, including all visits and follow-ups, would be explained in detail.

Common questions
What is 'bioequivalence'?
It means checking if a new version of a medicine works in exactly the same way as an older, established version, like comparing two brands of the same product.
Why do I need to fast before taking the medicine?
Fasting helps researchers see how the medicine is absorbed by your body without food affecting it, making the results clearer.
Will I be given the medicine to treat an illness?
No, this study is not about treating any medical condition. It's about testing the medicine itself in healthy people.
What kind of tests will I have?
You will mostly have blood samples taken regularly after taking the medicine, and your vital signs like blood pressure might be checked.
Do I get paid to take part?
Most studies like this offer payment or compensation for your time and any travel expenses.
