Bioequivalence of two transdermal therapeutic systems delivering 100 mcg/h fentanyl
This study is looking into two different types of skin patches that deliver a pain medication called fentanyl at a rate of 100 micrograms per hour. The main goal is to see if these two patches deliver the medication into the body in a very similar way. This is called a 'bioequivalence' study. It's an important step to ensure that if a new version of a medication patch is made, it works just as effectively and safely as one already approved. This trial is for healthy adults and is one of the very first stages of testing a new medication or medical device. It helps regulators confirm that patients will get a consistent and reliable dose, regardless of which approved patch they use.
At a glance
What is this study about?
This study is a research project looking at two different skin patches that deliver a pain medicine called fentanyl. Fentanyl is a strong pain reliever, and these patches are designed to release it slowly into your body over time. The study's main purpose is to see if two different brands or types of these patches actually deliver the medicine into your bloodstream in the same way and at the same speed. This is really important to ensure that if a new patch comes onto the market, it will work exactly like existing ones, providing the same pain relief without unexpected side effects.
Imagine you buy medicine from two different companies, but it's supposed to be the same drug and dose. This study makes sure that even if the patches look a bit different, they deliver the medication in a very similar way inside your body. This is crucial for patient safety and to make sure you always get the right amount of medication you need.
This kind of study is called a 'bioequivalence' study and is usually done in healthy volunteers. It's a very early stage of testing, often called a 'Phase I' study. The information gathered helps medicines regulators decide if a new version of a patch can be approved for general use, giving doctors and patients confidence that different brands of the same medication will work consistently.
Key takeaways
- This study compares two fentanyl patches to ensure they work similarly.
- It's a very early-stage safety and effectiveness check (Phase I).
- Only healthy adults aged 18 and over can take part.
- Participation involves clinic visits, patch application, and blood tests.
- The goal is to ensure consistent medication delivery for patient safety.
- You can withdraw from the study at any time.
Who may be eligible?
To take part in this study, you need to be a healthy adult aged 18 or older. The study is open to both men and women.
Being 'healthy' usually means you don't have any major medical conditions, you're not taking certain medications, and your organs (like your heart, liver, and kidneys) are all working well. Researchers will check this very carefully to make sure it's safe for you to take part.
There may be other specific reasons why you couldn't join, such as if you have allergies, are pregnant or breastfeeding, or have certain lifestyle habits. The study team will review your medical history in detail to confirm you meet all the safety requirements.
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 in good health?
- Are you not pregnant or breastfeeding?
- Are you willing to follow study instructions, including diet if requested?
- Do you understand that this is not a treatment study for an illness?
What does participation involve?
If you decide to take part, you would likely visit a research clinic several times. During these visits, you might have blood samples taken to measure how the medication is absorbed into your body over time. You would also have the study patches applied to your skin, and researchers would monitor you closely for any effects or side effects.
Your overall health would be regularly checked with things like blood pressure readings and perhaps heart traces (ECGs). You would receive different patches at different times to allow for comparison. The total duration of your participation would involve a series of visits over a period, likely several weeks, including follow-up appointments after the patches have been removed.

Common questions
What is fentanyl?
Fentanyl is a powerful pain-relieving medication, usually used for severe or ongoing pain. In this study, it's delivered through patches placed on the skin.
What does 'bioequivalence' mean?
It means the study is comparing two different versions of the same medicine to see if they deliver the active drug into your body in a very similar way and at the same rate. This ensures they work equally well.
Why is this study important?
It helps make sure that if a new version of a fentanyl patch is developed, it will be just as safe and effective as the original, giving doctors and patients confidence in its use.
Will I receive treatment for a medical condition?
No, this study is for healthy volunteers and is not designed to treat a medical condition. It's about how the medication is handled by the body.
Do I have to be sick to join?
No, quite the opposite! This particular study is looking for healthy volunteers, not people with specific illnesses or medical conditions.
