More Info

A pharmacokinetic study means that a participant will have a blood draw and possibly other body fluids taken a few times over a few hours to see how the study treatment was used by the body.

The PK study is done to find out how a drug is absorbed, moves through, is broken down, and exits the body.

Other info to think about when joining a study

If you enroll in a pharmacokinetic study a drug or medicine will be given to you and then blood samples will be taken several times over several hours to see how the study treatment was processed by your body.

If you have any questions about the drug or medicine being tested or how long the pharmacokinetic study will take, you could discuss them with the study team.
