Recruitment Details
Key information relevant to the recruitment process for the overall study, such as dates of the recruitment period and locations
Participants took part in this study at 3 investigative sites in the United States from 04 March 2010 to 09 February 2011.

Pre-Assignment Details
Significant events and approaches for the overall study following participant enrollment, but prior to group assignment
36 participants with gastroesophageal reflux disease were assigned to 1 of 3 once daily (QD) treatment regimens (15 mg, 30 mg or 60 mg dexlansoprazole) based on baseline body weight.

Reporting Groups

Dexlansoprazole 15 mg QD Dexlansoprazole 15 mg, delayed release capsules, orally, once daily for up to 7 days.
Dexlansoprazole 30 mg QD Dexlansoprazole 30 mg, delayed release capsules, orally, once daily for up to 7 days
Dexlansoprazole 60 mg QD Dexlansoprazole 60 mg, delayed release capsules, orally, once daily for up to 7 days

1.  Primary:   Time to Reach the Peak Plasma Concentration (Tmax)   [ Time Frame: Day 7 after 7 days of dosing with dexlansoprazole delayed release capsules. ]

2.  Primary:   The Peak Plasma Concentration (Cmax)   [ Time Frame: Day 7 after 7 days of dosing with dexlansoprazole delayed release capsules. ]

4.  Primary:   Area Under the Plasma Concentration Versus Time Curve (AUC) From Time 0 to 24 Hours Post-dose (AUC(0-24))   [ Time Frame: Day 7 after 7 days of dosing with dexlansoprazole delayed release capsules. ]

5.  Other Pre-specified:   Dose-normalized Peak Plasma Concentration (Cmax/Dose)   [ Time Frame: Day 7 after 7 days of dosing with dexlansoprazole delayed release capsules. ]

6.  Other Pre-specified:   Dose-normalized Area Under the Plasma Concentration Versus Time Curve (AUC) From Time 0 to Time of the Last Quantifiable Concentration (AUC(0-tlqc)/Dose)   [ Time Frame: Day 7 after 7 days of dosing with dexlansoprazole delayed release capsules. ]

7.  Other Pre-specified:   Dose-normalized Area Under the Plasma Concentration Versus Time Curve (AUC) From Time 0 to 24 Hours Post-dose (AUC(0-24)/Dose)   [ Time Frame: Day 7 after 7 days of dosing with dexlansoprazole delayed release capsules. ]
