Bioavailability Study for New Atorvastatin Formulation

An Open Label, Single Dose, Randomized 2-Way Crossover Study To Estimate The Relative Bioavailability Of Atorvastatin Commercial Tablet, And An Extemporaneous Preparation (EP) Suspension Formulation, In Healthy Subjects

The purpose of this study is to estimate the relative bioavailability of the commercial tablet with one prototype extemporaneous preparation suspension formulation, to assist with internal decision making on formulation development.

Primary Outcome Measures

Outcome Measure
Measure Description
Time Frame
Area Under the Curve From Predose (Time Zero) to 48 Hours Post-dose (AUC48)
Time Frame: 5 days
Geometric means of AUC48 = area under the plasma concentration-time profile from time zero (0) to 48 hours postdose of atorvastatin (test versus [vs] reference); measured in nanograms times hour per milliliter (ng.hr/mL).
5 days
Area Under the Curve From Predose (Time Zero) to Extrapolated Infinite Time (AUC Infinity)
Time Frame: 5 days
Geometric means of AUC infinity (AUCinf) = area under the plasma concentration-time curve from time zero (0) extrapolated to infinite time; measured in ng.hr/mL of atorvastatin (test vs reference).
5 days
Maximum Observed Plasma Concentration (Cmax)
Time Frame: 5 days
Geometric mean of Cmax = maximum observed plasma concentration of atorvastatin (test vs reference); measured in nanograms per milliliter (ng/mL).
5 days

Secondary Outcome Measures

Outcome Measure
Measure Description
Time Frame
Area Under the Curve From Predose (Time Zero) to Last Quantifiable Concentration (AUClast)
Time Frame: 5 days
Geometric mean of AUClast = area under the plasma concentration-time curve from time zero (0) to the last measurable concentration of atorvastatin (test vs reference); measured as ng.hr/mL
5 days
Terminal Phase Rate Constant (Kel)
Time Frame: 5 days
Geometric mean of Kel= termination phase rate constant for atorvastatin (test vs reference); measured as 1 per hour (1/hr).
5 days
Time to Reach Maximum Plasma Concentration (Tmax)
Time Frame: 5 days
Median of Tmax = time to maximum plasma concentration (Cmax) (test vs reference); measured in hours (hr).
5 days
Plasma Elimination Half-life (t1/2)
Time Frame: 5 days
Mean of t1/2 = terminal elimination half-life of atorvastatin (test vs reference); measured in hours.
5 days
