Brief Summary

This study was a single-center, randomized, open-label, two-agent, two-cycle, double-cross bioequivalence trial.

Detailed Description

The objectives of this study are to evaluate the difference of absorption degree and absorption rate of two kinds of patches( FB3002 vs. Loxonin®) in Chinese healthy population, and to assess the bioavailability of these two patches.

Primary Outcome Measures
NameTimeMethod
AUC0-∞ of loxoprofen and its trans-OH0-72 hours

Area under the plasma concentration curve from time 0 to ∞ (AUC0-∞). Analyzing AUC with ANOVA test to evaluate the 90% confidence interval for the ratio (Test/Reference) of the population mean with a logarithmic transformation prior to analysis with acceptance interval of 0.80 - 1.25.

Cmax of loxoprofen and its trans-OH0-72 hours

Maximum plasma concentration. Analyzing AUC with ANOVA test to evaluate the 90% confidence interval for the ratio (Test/Reference) of the population mean with a logarithmic transformation prior to analysis with acceptance interval of 0.80 - 1.25.

AUC0-T of loxoprofen and its trans-OH0-72 hours

Area under the plasma concentration curve from time 0 to the last measured (AUC0-t).

Analyzing AUC with ANOVA test to evaluate the 90% confidence interval for the ratio (Test/Reference) of the population mean with a logarithmic transformation prior to analysis with acceptance interval of 0.80 - 1.25.

Secondary Outcome Measures
NameTimeMethod
Tmax of loxoprofen and its trans-OH0-72 hours

Time to reach maximum plasma concentration

t1/2 of loxoprofen and its trans-OH0-72 hours

Apparent terminal elimination half-life

λz0-72 hours

Apparent terminal elimination rate constant

Adverse Events0-14 days

All of the adverse events will be reported

AUC_%Extrap0-72 hours

Percentage of AUCINF(_obs, _pred) due to extrapolation from Tlast to infinity

Irritation score0-14 days

A combined irritation score should be calculated by adding the "dermal response" score and the numeric equivalent for "other effects" letter score.
