PRIMARY outcome

Timeframe: Predose and up to 24 hours postdose

Population: The Hodges-Lehmann estimator was used to analyze nicotinuric acid Cmax and uses only subjects with data available on both treatment periods. 188 subjects were randomized,17 subjects discontinued, 26 subjects were inadvertently overdosed with 5 tablets of MK0524A 1000 mg/20 mg, reducing the available subject population for analysis to 145.
