Evaluation of the Pharmacodynamics of a Heparin With Its Biological Comparator, Subcutaneous Administration

Randomized, Open-label, Single-dose, Crossover Study to Evaluate the Pharmacodynamics of an Unfractionated Heparin Compared to Heparin Sodium Injection, USP (Comparator) After Subcutaneous Administration in Healthy Subjects

Experimental Drug: Porcine sodium heparin, injectable solution - 5,000 IU/ 0.25 mL; Blau Farmacêutica S/A.

Comparator Drug: Heparin Sodium Injection, USP, injectable solution - 5,000 IU/ 0.5 mL; Fresenius Kabi Lake Zurich.
