PK-PD Comparative Study of Lansoprazole Capsules and Lansoprazole Enteric-coated Capsules in Healthy Chinese Volunteers

A Randomized, Open Label, Parallel, Single and Multiple Doses Designed Clinical Study to Evaluate Comparative Pharmacokinetics (PK)-Pharmacodynamics (PD) After Oral Administration of Lansoprazole Capsules and Lansoprazole Enteric-coated Capsules in Healthy Chinese Volunteers

The objective of this study was to compare the relative PK-PD of Lansoprazole Capsules and Lansoprazole DR Capsules in healthy Chinese volunteers.

Study Overview

What is the study measuring?

Primary Outcome Measures

Outcome Measure	Measure Description	Time Frame
Pharmacokinetics Assessment	Cmax: Maximum Observed Plasma Concentration for lansoprazole Maximum observed plasma concentration (Cmax) is the peak plasma concentration of a drug after administration, obtained directly from the plasma concentration-time curve.[Time Frame: 16 hours post-dose on Day 1 and D7]; TmaxTime to Reach the Maximum Plasma Concentration [Time Frame: 16 hours post-dose on Day 1 and D7]; AUC(0-inf): Area Under the Plasma Concentration-time Curve from Time 0 to Infinity for lansoprazole AUC (0-inf) is a measure of total plasma exposure to the drug from time zero extrapolated to infinity [Time Frame: Time Frame: 16 hours post-dose on Day 1 and D7] model.	16 hrs post-dose on day 1 and day 7.
PD Assesment	Percentage time with the intragastric potential of hydrogen (pH)<4 Duration of intragastric pH<4 within 24 hours postdose; Percentage time with the intragastric pH>6 Duration of intragastric pH>6 within 24 hours postdose; The time of the intragastric pH reaching 4The time of intragastric pH reaching 4 after the last dos; The time of the intragastric pH reaching 6The time of intragastric pH reaching 6 after the last dose	24 hrs post-dose on day 1 and day 7.

Secondary Outcome Measures

Outcome Measure	Measure Description	Time Frame
Duration of intragastric pH within 24 hours postdose	ean intragastric pH per hour Mean intragastric pH per hour Percentage time with the intragastric pH>4 during the first 4 hours Duration of intragastric pH>4 within first 4 hours postdose Percentage time with the intragastric pH>6 during the first 4 hours Duration of intragastric pH>6 within first 4 hours postdose Percentage of the participants with duration time of intragastric pH>4 over 12hNumbers of participants with duration time of intragastric pH>4 over 16h Percentage of the participants with duration time of intragastric pH>6 over 12h Numbers of participants with duration time of intragastric pH>6 over 16h intragastric pH<4 within 24 hours postdose	24 hrs after dose on day 1 and 7
