Bindingen er 95% ved plasma koncentrationer under 100 mg/ l med en bindingsprocent der falder i takt med at koncentrationen øges (til 85% ved ceftriaxon plasma koncentrationer af 300 µg/ ml).
The binding is 95% at plasma concentrations less than 100 mg/ l with the binding percentage decreasing as the concentration increases (to 85% at ceftriaxone plasma concentrations of 300 µg/ ml).
