- MK-0524A produces less flushing during the acute dosing period than niacin extended-release as measured by maximum Global Flushing Severity Score (GFSS) categorized as none/mild, moderate, severe, extreme. [ Time Frame: Over 1 week ]
- MK-0524A produces less flushing during the acute dosing period than niacin extended-release as measured by (a) maximum daily GFSS; and (b) percentage of patients with a maximum GFSS =4 (moderate or greater). [ Time Frame: Daily ]
