Primary Outcome Measures:
- AUC 0-t [ Time Frame: Day 1 (day that blood collections started) to Day 4 (Period 1) and Days 8 to 11 (Period 2) ] [ Designated as safety issue: No ]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.
- AUC0-infinity [ Time Frame: Day 1 (day that blood collections started) to Day 4 (Period 1) and Days 8 to 11 (Period 2) ] [ Designated as safety issue: No ]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 [ Time Frame: Day 1 (day that blood collections started) to Day 4 (Period 1) and Days 8 to 11 (Period 2) ] [ Designated as safety issue: No ]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.

Detailed Description:
It will be an open-label, randomized, laboratory-blind, crossover study with 02 treatments, 02 sequences, and 02 periods, in which the volunteers receive, in each period, the test formulation or the reference formulation, under fed conditions.
The treatment's sequence attributed to each volunteer on the study period is determined by a randomization list, which is generated by PROC PLAN from SAS version 9.1.3 system.
The formulations will be administered as a single oral dose followed by blood collections between, at least, 3 to 5 half-lives. The treatment's periods may obey a minimum interval of 7 half lives between them (period for drug's whole elimination by the organism).
