Further study details as provided by GlaxoSmithKline:

Primary Outcome Measures:
  • Steady-state Cmax and AUC (0-t) of atorvastatin [ Time Frame: Pre-dose,0.25, 0.5, 1, 1.5, 2, 2.5, 3, 4, 6, 8, 10, 12, 16, 20 and 24 hrs post dose. ] [ Designated as safety issue: No ]
    Steady-state Cmax and AUC (0-t) of atorvastatin when dosed to steady-state.


Secondary Outcome Measures:
  • To assess the effect of lamotrigine or phenytoin on the pharmacokinetics of 2-OH atorvastatin and 4-OH atorvastatin [ Time Frame: Pre-dose, 0.25, 0.5, 1, 1.5, 2, 2.5, 3, 4, 6, 8, 10, 12, 16, 20 and 24 hrs post dose. ] [ Designated as safety issue: No ]
    Steady state Tmax, Cmax and AUC of 2-OH atorvastatin and 4-OH atorvastatin in the presence and absence of LTG XR or phenytoin.
