结局指标
主要结局
The Steady State Area Under the Drug Concentration Time Curve From 0 to 12 Hours Post Dose AUC(0-12).
时间窗: 0 and 1,2,3,4,5,6,8, and 12 hours after the last dose
AUC(0-12) was based on blood samples taken at specified outcome measure time frame for dalfampridine-ER 7.5 mg tablets in healthy adult volunteers and people with mild or moderate renal impairment.
次要结局
