OBJECTIVE:: Niacin is underutilized due to flushing, which occurs in over 90% of niacin-treated patients. Laropiprant (LRPT) reduces flushing associated with niacin. This study compared flushing with a combination tablet of extended-release (ER) niacin (ERN)/LRPT to niacin ER (N-ER; without LRPT) during the first week of therapy among patients in Asia. METHODS:: Following a 1-week placebo run-in, 332 patients with dyslipidemia from China, Korea and Singapore were randomized to ERN/LRPT 1 g/20 mg, N-ER 1 g (given as Niaspan®) or placebo in a 2:2:1 ratio for 1 week. Patient-reported flushing severity was assessed using the Global Flushing Severity Score (GFSS; none/mild = 0-3; moderate = 4-6; severe = 7-9; extreme = 10). RESULTS:: Compared with N-ER, the ERN/LRPT group experienced significantly less flushing (p < 0.001), as measured by maximum GFSS categorized as none/mild, moderate, severe or extreme. Overall, 23.8% of patients in the ERN/LRPT group and 50.0% in the N-ER group (p < 0.001), versus 12.1% in the placebo group, had moderate or greater flushing (GFSS ≥4). Except for flushing, which occurred more frequently in the N-ER group, ERN/LRPT had a safety/tolerability profile similar to that of N-ER. CONCLUSION:: ERN/LRPT produced significantly less flushing than N-ER during the initiation of therapy and was generally well tolerated in Asian patients with dyslipidemia.
