Primary Outcome Measures:
  • Area under the concentration-time curve (AUC) of plasma glucagon during the standard meal test (SMT) [ Time Frame: Days 5, 10, and 14 ] [ Designated as safety issue: No ]

Secondary Outcome Measures:
  • Plasma glucose, serum insulin, and serum C-peptide AUCs during the SMT [ Time Frame: Days 5, 10, and 14 ] [ Designated as safety issue: No ]
  • Collapse under Acetaminophen PK [ Time Frame: Days 5 and 10 ] [ Designated as safety issue: No ]
  • Area under the plasma acetaminophen concentration-time curve from time 0 to 240 min (AUC0-240 min) [ Time Frame: Days 5 and 10 ] [ Designated as safety issue: No ]
  • Collapse all under ranolazine pharmacokinetics (PK) [ Time Frame: Days 5 and 10 ] [ Designated as safety issue: No ]
  • Trough plasma ranolazine concentrations (Ctrough) [ Time Frame: Days 5 and 10 ] [ Designated as safety issue: No ]
  • Average plasma ranolazine concentration during a dosing interval at steady state (Css,ave) [ Time Frame: Days 5 and 10 ] [ Designated as safety issue: No ]
  • Area under the plasma ranolazine concentration-time curve over dosing interval (AUCtau) [ Time Frame: Days 5 and 10 ] [ Designated as safety issue: No ]
  • Apparent elimination half-life (t1/2) of ranolazine [ Time Frame: Days 5 and 10 ] [ Designated as safety issue: No ]
  • Adverse events, physical examinations, clinical laboratory determinations, electrocardiograms (ECG), and vital sign assessments. [ Time Frame: From Screening to 7 days after the final dose ] [ Designated as safety issue: Yes ]
