Trial Outcomes & Findings for SECOTEX® (Tamsulosin Hydrochloride) Bioequivalence Study Brazil - Fed Admin (NCT NCT01330303)

NCT ID: NCT01330303

Last Updated: 2017-08-01

Results Overview

The area under the plot of plasma concentration of drug against time after drug administration is defined as the area under the curve (AUC). The AUC from time 0 (prior to administration of medication) to time t (the time of the last quantifiable concentration) was calculated using the trapezoidal method. This method consists of the sum of the trapezoids' areas, determined by the collection times and their concentrations. The AUC is of particular use in estimating the bioavailability of drugs, by measuring the extent of absorption. ng, nanograms; ml, milliliter.

The area under the plot of plasma concentration of drug against time after drug administration is defined as the area under the curve (AUC). The AUC from time 0 (prior to administration of medication) to infinity (the time of complete elimination of the drug) was calculated using the trapezoidal method. This method consists of the sum of the trapezoids' areas, determined by the collection times and their concentrations. The AUC is of particular use in estimating the bioavailability of drugs, by measuring the extent of absorption.

Cmax is defined as the maximum or "peak" concentration of a drug observed after its administration. Cmax is one of the parameters of particular use in estimating the bioavailability of drugs, by measuring the total amount of drug absorbed.
