| Experimental: Lansoprazole Capsules<br>Lansoprazole Capsules 30 mg of Beijing Sihuan Pharm | Drug: Lansoprazole capsules<br>* Test 1: 30 healthy volunteers will be included and randomized into 3 groups (10 for each). During the study session, subjects will receive a single dose of Lansoprazole capsules 30 mg in sequence of T-R-R in group A; R-T-R in group B; and R-R-T in group C. Test 2: 12 healthy volunteers will be recruited and randomized to 2 groups (6 for each). Subjects in group A will receive a single dose of experimental drug in sequence of fast-fed condition; while in group B, subjects will receive the same dose and drug but in fed-fast order.<br>|

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] TmaxTime to Reach the Maximum Plasma Concentration [Time Frame: 16 hours post-dose on Day 1] 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] AUC(0-16h): Area Under the Plasma Concentration-Time Curve From Time 0 to 36 hours Postdose for lansoprazoleAUC(0-36h) is measure of area under the plasma concentration and time curve from Time 0 to 36 hours postdose. [Time Frame: 16 hours post-dose on Day 1] model. | 16 hrs post-dose on day 1. |
