Bioequivalence clinical trial of two formulations of bilastine.
This research study is looking at two different forms (formulations) of a medicine called bilastine, which is used for allergies like hay fever. The main goal is to see if both versions of the medicine are absorbed into the body in the same way and at the same speed. This is called a 'bioequivalence' study. We are looking for healthy volunteers, aged 18 and over, of any gender. This is an early-stage study, meaning it helps ensure new generic versions of medicines are just as effective and safe as the original. Participating helps ensure people have access to reliable medicines.
At a glance
What is this study about?
This clinical trial is designed to compare two different versions of a medicine called bilastine. Bilastine is commonly used to treat symptoms of allergies, such as hay fever, by blocking histamine, a chemical in the body that causes allergic reactions. When different companies make a medicine, or when a medicine is made slightly differently (a new 'formulation'), it's very important to check that the body takes it in and uses it in the same way as the original or standard version. This ensures that people get the same treatment effect, no matter which version they take.
The main purpose of this study, often called a bioequivalence study, is to see if the two bilastine formulations deliver the same amount of medicine to the bloodstream over the same amount of time. This isn't about seeing if the medicine works to stop allergies – that's already known. Instead, it's a careful check to make sure the body processes two different forms of the same medicine in an identical way. If they are 'bioequivalent,' it means they are effectively interchangeable.
This kind of study is a crucial step in developing new medicines, especially when a generic version of a drug is being made available. By making sure different versions of a medicine work the same way in the body, we can help ensure that patients receive consistent and effective treatment, and that safe and affordable options are available.
Key takeaways
- This study compares two versions of the allergy medicine bilastine.
- It aims to ensure both versions are absorbed by the body in the same way.
- Participants must be healthy and aged 18 or older.
- Participation involves clinic visits and blood tests.
- Your contribution helps ensure safe and effective medicines are available.
- You can stop participating at any time.
Who may be eligible?
This study is looking for participants who are generally healthy. You don't need to have an illness or specific condition to join; in fact, the study specifically focuses on healthy individuals to clearly see how the medicine is absorbed without other health issues getting in the way.
To be considered for this study, you must be at least 18 years old. There is no upper age limit mentioned, so older adults who are otherwise healthy may also be eligible. Both men and women are welcome to participate.
Before you can take part, a medical team will carry out some checks to make sure you are healthy enough for the study. This will likely involve a medical history review, a physical examination, and some blood tests to confirm your general health. You will also be fully informed about what's involved to help you decide if it's right for you.
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?
- Are you able to attend clinic visits regularly?
- Are you comfortable with blood samples being taken?
- Are you not currently pregnant or breastfeeding (if applicable for women)?
What does participation involve?
If you decide to take part in this study, you will be asked to visit a research clinic several times. During these visits, you will receive doses of the bilastine medicine. Sometimes, you might be asked to stay at the clinic for a short period, especially after taking the medicine, so that blood samples can be taken regularly. These samples help researchers measure how much of the medicine is in your bloodstream over time.
You will receive both versions of the bilastine medicine at different times, though you won't know which one you are taking at any given point. Between taking the different medicines, there will be a 'washout period' where you won't take any study medication, to make sure the first dose is completely out of your system before the next one. Your health will be monitored throughout the study, and you'll have check-ups to make sure you're feeling well. The total duration of your participation, including all visits and follow-up, will be explained in detail before you agree to join.

Common questions
What is bilastine?
Bilastine is a medicine used to treat allergy symptoms, like hay fever or hives, by blocking a chemical in your body called histamine.
Why are you studying healthy people?
By studying healthy people, researchers can clearly see how the medicine is absorbed and processed by the body without any other health conditions making it complicated.
Is this medicine new?
Bilastine itself is a known medicine. This study is testing if different versions or ways of making bilastine work in the same way as the original.
Will I get paid for taking part?
It's common for healthy volunteer studies to offer some payment for your time and inconvenience. The study team will explain this to you.
What does 'bioequivalence' mean?
Bioequivalence means that two different versions of a medicine deliver the same amount of active drug into your bloodstream at the same speed, making them work the same way.
