To determine if administration of naproxen sodium 220 mg maintains the platelet inhibitory effect of a low dose Immediate Release Aspirin (IR ASA) regimen.

Conditions

Hematology

Outcome Measures

Primary Outcomes (1)

• Inhibition of Serum Thromboxane B2 (TXB2) on Day 16 at 24 Hour Post IR ASA 81 mg Administration

  Inhibition of serum TXB2 at specified time point was calculated using the percentage of reduction from baseline as follows: Inhibition (%) = 100 × (Baseline Value - Post-baseline Value) / Baseline Value. For primary analysis, the mean and the lower bound of the corresponding one-sided 95% Confidence Interval (CI) were calculated.

  At hour 24 on Day 16 post treatment

Secondary Outcomes (3)

• Inhibition of Serum TXB2 on Days 7, 16, 17, and 19 of the In-house Treatment Period at 1, 3, 6, 12, 18, and 24 Hours (Except at 24 Hours on Day 16) Post IR ASA 81 mg Administration

  At 1, 3, 6, 12, 18, and 24 hours on Days 7, 16, 17, and 19 (except 24 hours on Day 16)

• Inhibition of Arachidonic Acid (AA)-Induced Platelet Aggregation on Days 7, 16, 17, and 19 at 1, 3, 6, 12, 18, and 24 Hours Post IR ASA 81 mg Administration

  At 1, 3, 6, 12, 18, and 24 hours on Days 7, 16, 17, and 19

• Inhibition of TXB2 Using Platelet-rich Plasma (PRP) on Days 7, 16, 17, and 19 of the In-house Treatment Period at 1, 3, 6, 12, 18, and 24 Hours Post IR ASA 81 mg Administration

  At 1, 3, 6, 12, 18, and 24 hours on Days 7, 16, 17, and 19
