Brief Summary:

The study will be a double-blind, randomized, placebo-controlled, single-center, 2 treatment, 3-­way crossover. Subjects will be randomly allocated to a treatment sequence – AAB, ABA or BAA. The two treatments will be:

  • Treatment A: 500 mg nicotinic acid (Niacor(R))
  • Treatment B: Niacor(R) Placebo

Each trial period will last one day, there will be a wash-out period of at least 2 days between each trial period. Five to seven days after study day 1 of trial period 3 there will be a final safety examination.

  • Pregnancy or lactation
  • Subject is the investigator or any sub-investigator, research assistant, pharmacist, study coordinator, other staff or relative thereof directly involved in the conduct of the protocol
  • Mental condition rendering the subject unable to understand the nature, scope, and possible consequences of the study
