Brief Summary:

RATIONALE: Giving healthy volunteers sulindac capsules or sulindac tablets may help doctors learn which form of the drug may be more effective in preventing cancer.

PURPOSE: This randomized clinical trial is studying sulindac capsules to see how well they work compared with sulindac tablets in healthy volunteers.

Condition or disease Intervention/treatment Phase
Unspecified Adult Solid Tumor, Protocol Specific Drug: sulindac Other: pharmacological study Not Applicable

Detailed Description:



  • Compare the systemic exposure of sulindac tablets vs sulindac capsules in healthy volunteers.


  • 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.

Study Type : Interventional  (Clinical Trial)
Estimated Enrollment : 28 participants
Allocation: Randomized
Primary Purpose: Prevention
Official Title: Bioequivalency Study of Sulindac in Capsule vs. Tablet Formulations
Study Start Date : April 2006
