Plasma argatroban concentrations after s.c. administration of 2 mg·kg⁻¹ in pigs using solutions with different concentrations: 5 (open triangles), 15 (closed rhombus), 30 (open circles), 50 (open squares), and 100 mg·mL⁻¹ (closed circles). Results are expressed as the mean plasma concentration (μg·mL⁻¹) of , showing the standard deviation at each sampling time.
