Consequently, water-soluble drugs are not well distributed throughout the body. They exist in large amounts in the plasma or tissue fluid and are rapidly cleared by the liver or kidney. In practice, such drugs have little therapeutic use.
At equilibrium, drugs are partitioned between plasma, plasma proteins and the different tissues.
