Study Arms (1)
Niacin and Endotoxin
EXPERIMENTALAll subjects are expected to have the same interventions- Niacin and 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).
