Primary Outcome Measures:
  • To assess the single-dose pharmacokinetics and relative bioavailability of esomeprazole in PN 400 (naproxen 500mg / esomeprazole 20mg), the enteric-coated (EC) naproxen 500mg plus EC esomeprazole 20mg and the EC esomeprazole 20mg alone treatments [ Time Frame: 12-72 hour PK assessments ] [ Designated as safety issue: No ]

Secondary Outcome Measures:
  • To assess the single-dose pharmacokinetics and relative bioavailability of naproxen in PN 400 (naproxen 500mg / esomeprazole 20mg, the EC naproxen 500mg plus EC esomeprazole 20mg, and the EC naproxen 500mg alone treatments. [ Time Frame: 72-hour PK assessments ] [ Designated as safety issue: No ]
  • To evaluate the safety of each of the single-dose treatments [ Time Frame: Entire study duration (48 days) ] [ Designated as safety issue: Yes ]

Detailed Description:

This study is being conducted to assess the relative bioavailability of naproxen and esomeprazole from a single dose of PN 400 (delayed-release naproxen 500mg / immediate-release esomeprazole 20mg), enteric-coated naproxen 500mg co-administered with enteric-coated esomeprazole 20mg, enteric-coated naproxen 500mg administered alone, and enteric-coated esomeprazole 20mg administered alone.
