Trial Information

Bioequivalency Study of Sulindac in Capsule vs. Tablet Formulations



- Compare the systemic exposure of sulindac tablets vs sulindac capsules in healthy


- Compare the terminal half-life and time of peak drug concentration of sulindac tablets
vs sulindac capsules.

OUTLINE: This is a randomized study. Participants are randomized to 1 of 2 treatment arms.

- Arm I: Participants receive one sulindac capsule followed 7-10 days later by one
sulindac tablet.

- Arm II: Participants receive one sulindac tablet followed 7-10 days later by one
sulindac capsule.

Blood is collected periodically during treatment for pharmacokinetic studies.

After completion of study therapy, participants are followed at 7-10 days.

PROJECTED ACCRUAL: A total of 28 participants will be accrued for this study.
