Additional information

In this trial we will look at the levels of the approved drug salbutamol in the blood. This drug is already available on the market for the treatment of respiratory conditions such as asthma and COPD. Salbutamol is administered by using an inhaler (puff). An inhaler contains the active ingredient (medicine) salbutamol and a propellant which helps to dispense the medicine out of the device for it to be inhaled by the user. The propellant that is currently used in inhalers to dose salbutamol has a significant global warming potential. Therefore, an alternative propellant that is less harmful for the environment will be tested.

The second screening will be for a spirometry assessment, which will be performed in Groningen once you have passed the first medical screening.

Period of stay and research

The trial consists of 1 period during which you will stay in the research facility in Groningen (location van Swietenlaan 6) for 12 days (11 nights). The follow-up visit will be telephonic and will take place within 7 days after your departure from the research facility.

Frequently asked questions

You can participate in a trial a maximum of four times a year. There must be at least 30 days between two trials. Some trials have a longer waiting period.

During the trial, you may suffer from mild symptoms like headache or nausea. That may be caused by the medication. It might also be caused by needing to fast for the trial, for example. Those side effects are no fun, but fortunately are not dangerous.

Before a medication is tested on people, it has already been studied extensively in a lab. This enables us to predict well which side effects you might get and we can prepare you for them. It almost never happens that participants suffer from unexpected side effects. For example, an allergic reaction to the medication occurs on average once a year.

A trial usually involves 5 to 12 participants. The groups are set up so they best match the requirements of the trial. These requirements are described for each trial. View all current trials.
