Short-Term Effects of Extended-Release Niacin With and Without the Addition of Laropiprant on Endothelial Function in Individuals With Low HDL-C: A Randomized, Controlled Crossover Trial

In these patients, the addition of laropiprant did not influence the effects of niacin on endothelial function. Based on these findings, short-term niacin treatment might improve endothelial function in patients with low HDL-C levels. ClinicalTrials.gov identifier: NCT01942291.
