A new tablet form of PF-04531083 has been manufactured. Previously the compound was administered as a solution/suspension to healthy volunteers. This study will investigate the pharmacokinetics of PF-044531083 in tablet form and compare with the pharmacokinetics obtained, with the same dosing regimen, with the solution/suspension.

Further study details as provided by Pfizer:

Primary Outcome Measures:
  • concentration of PF-04531083 in blood just before dosing on the 8th day of the study [ Time Frame: Days 1 and 8 of the study ] [ Designated as safety issue: No ]

Secondary Outcome Measures:
  • pharmacokinetic parameters derived from the plasma concentration versus time profile of PF-04531083 following single and multiple dosing. AUCtau, Cmax, Tmax will be calculated. [ Time Frame: Days 1, 8 and 14 of the study ] [ Designated as safety issue: No ]
