The purpose of this study is to assess the pharmacokinetics after a single dose of dexlansoprazole 30 and 60 mg delayed-release capsules in healthy Chinese participants.

The drug being tested in this study is called Dexlansoprazole. This study will assess the pharmacokinetics, safety and tolerability of a single oral dose of Dexlansoprazole 30 mg and 60 mg delayed-release capsules in healthy participants.

The study will enroll approximately 40 participants, 20 participants in each parallel arm. Participants will be randomly assigned (by chance, like flipping a coin) to one of the two treatment groups:

• Group 1: A single oral dose of Dexlansoprazole 30 mg delayed-release capsule
• Group 2: A single oral dose of Dexlansoprazole 60 mg delayed-release capsule

All participants will be asked to take single dose of study drug on Day 1.

This single center trial will be conducted in China. The overall time to participate in this study is approximately 40 days. Participants will be contacted by telephone or will make a final visit to the clinic 5 to 10 days after receiving their last dose of study drug for a follow-up assessment.

At each visit the investigator had to document any occurrence of adverse events and abnormal laboratory findings. Any event spontaneously reported by the participant or observed by the investigator was recorded, irrespective of the relation to study treatment.
