Free fraction

From Wikipedia, the free encyclopedia

The free fraction is a parameter in pharmacokinetics and receptor-ligand kinetics. One speaks of two different free fractions:

  • Plasma free fraction, previously referred to as f1,[1] is now referred to as fP according to consensus nomenclature.[2]
  • Tissue free fraction, previously referred to as f2[1]
