PK and PD Study After Single Dose, Intravenous Administration of Two Epoetin Alfa, Eritromax and Eprex, in Healthy Subjects

Study Overview
=================
Brief Summary
-----------------
The hypothesis of this trial is that the test drug (Eritromax ®) pharmacokinetics and pharmacodynamics parameters are similar to the comparator drug (Eprex ®) in healthy subjects following administration of single intravenous dose. The objective of this randomized, crossover, clinical trial is to evaluate the pharmacokinetic and pharmacodynamic profile of the drug Eritromax® marketed by Blau Farmacêutica, compared to the product Eprex ®, produced by Janssen-Cilag, by assessing plasma concentration of the drug and the reticulocyte count following a single-dose intravenous administration of 100 IU/kg in healthy subjects.
