Effect of Drugs, Safety Issues
Conditions
Brief summary
This is a single center, open-label, multiple-dose phase 1 clinical trial. This study will determine the pharmacokinetics (PK), pharmacodynamics (PD), safety and side-effect profile of an investigational dexlansoprazole injection after multiple intravenous administration in healthy Chinese adults.
Detailed description
This is a single center, open-label, multiple-dose clinical trial. 5 dosing groups were designed, including 15mg q12h,30mg q12h,15mg qd,30mg qd in dexlansoprazole treatment arm for 5 days, and 30 mg q12h in an active comparator, lansoprazole, treatment arm for 5 days. The study will enroll approximately 70 participants with 14 cases in each group. Participants will make 3 visits to the clinic including 8-day of confinement to the clinic.
Interventions
15mg q12h,30mg q12h,15mg qd,30mg qd for 5 days
