Outcome Measures

Primary Outcomes (1)

  • Baseline and Peak TNF-alpha Values as Categorized by Race and Gender

    Baseline (-15 min, -5 min), and 1, 2, 4, 6, 12, 18, and 24 hours post LPS

Secondary Outcomes (1)

  • Baseline and Peak C-Reactive Protein (CRP) Values as Categorized by Race and Gender

    Baseline ( -15 min, -5 min), and 1, 2, 4, 6, 12, 18, and 24 hours post LPS

Study Arms (1)

Niacin and Endotoxin

EXPERIMENTAL

All subjects are expected to have the same interventions- Niacin and Endotoxin.

Drug: Immediate Release Niacin, Extended Release Niacin, Endotoxin

Interventions

Subjects receive a one-time 1000mg dose of immediate release Niacin (Niacor pills), a one-time 1000mg dose of extended release Niacin (Niaspan pill) and one-time 1ng/kg injection of endotoxin (LPS).

Also known as: Niacor, Niaspan
Niacin and Endotoxin
