简要总结
To determine whether 8 weeks of Niaspan treatment increases cholesterol efflux in male subjects with low HDL-C cholesterol when compared to no treatment.
To determine whether 8 weeks of Niaspan treatment increases fecal cholesterol excretion when compared to no treatment.
To determine whether 8 weeks of Niaspan treatment increases the rate of global reverse cholesterol transport when compared to no treatment.
详细描述
This will be a single center, open-label, randomized, mechanism of action study consisting of 8 weeks of active treatment preceded by a screening phase from one to 8 weeks and a baseline measurement of parameters of reverse cholesterol transport for 10 days. The population for this trial is 15 non-diabetic men aged 18-70 years. Ten subjects will be low HDL-C male volunteers who will receive aspirin and Niaspan and five subjects will be low HDL-C male volunteers who will receive only aspirin.

- •Avoidance of extreme change of physical activity from screening through the follow-up period.
排除标准
- •Subjects are excluded from participation in the study if any of the following criteria apply:
- •History of intolerance to Niacin or Niaspan.
