"Webb30 nov. 2009 · 1. Binding of drug to blood/ plasma protein. Plasma protein binding. Most drugs, after absorption from gut, transported in to forms: free form and bind form. In case of free form, the drug is solubilised in plasma and transported. If the drug is in the bind form it means that it is bound with the plasma components like proteins, blood cells etc. " - Protein bound drug
