  Purpose

The purpose of this study is to determine how pioglitazone and aspirin affect platelets in the blood of diabetic and non-diabetic subjects. Platelets are small cells in the blood that help with blood clotting. Pioglitazone is a drug that is used to lower blood sugar and fats by helping the body to use insulin correctly. Pioglitazone is presently used to treat diabetes but has not been approved for non-diabetics. This study will determine whether pioglitazone reduces the activity of platelets in people who are or are not also taking aspirin.

Primary Outcome Measures:
  • To determine how pioglitazone and aspirin affect platelets in the blood of diabetic and non-diabetic subjects. [ Time Frame: 6-9 days ] [ Designated as safety issue: No ]

Enrollment: 40
Study Start Date: December 2008
Estimated Study Completion Date: December 2010
Primary Completion Date: June 2010 (Final data collection date for primary outcome measure)
Arms Assigned Interventions
Experimental: Pioglitazone
Blood samples will be taken at time 0 to measure platelet aggregation. 30mg Pioglitazone will be ingested and another blood sample will be obtained 90-180 minutes later for platelet aggregation.
Drug: Pioglitazone
30mg Pioglitazone x1
Other Name: Actos
Experimental: Pioglitazone + 81mg Aspirin
After 6-9 days, subjects will ingest 81mg of aspirin. Another blood sample will be obtained 2-24 hours later for baseline determination of platelet aggregation and activation after taking aspirin. Subjects will then ingest 30mg pioglitazone and a final blood sample will be obtained 90-180 minutes later to measure platelet aggregation.

Detailed Description:

Blood samples will be taken at time 0 to measure platelet aggregation. 30mg Pioglitazone will be ingested and another blood sample will be obtained 90-180 minutes later for platelet aggregation. After 6-9 days, subjects will ingest 81mg of aspirin. Another blood sample will be obtained 2-24 hours later for baseline determination of platelet aggregation and activation after taking aspirin. Subjects will then ingest 30mg pioglitazone and a final blood sample will be obtained 90-180 minutes later to measure platelet aggregation.

Criteria

Inclusion Criteria:

  • Subjects must be over 21 years of age and provide written informed consent.
  • Normal subjects must have a BMI <30 and must not have known cardiovascular disease, Diabetes Mellitus (DM), hyperlipidemia, or hypertension. Diabetic subjects must have previously diagnosed DM.
