Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

The aim of the present study was to compare the pharmacokinetic profiles and to evaluate the bioequivalence of two commercial amoxicillin-suspension formulations in healthy Brazilian volunteers.

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

Under fasting condition, 25 volunteers (13 males and 12 females) were included in this randomized, open-label, two-period crossover (1-week washout interval) bioequivalence study. Blood samples were collected at pre-dose (0h) and 0.5, 1, 1.33, 1.66, 2, 2.5, 3, 4, 6, 8 and 12 hours after drug ingestion. Pharmacokinetic parameters (Cmax, Tmax, T1/2, Area-under-curve0-12h and Area-under-curve0-inf) were calculated from plasma concentrations for both formulations in each subject.
