Abstract:
Most drugs are carried from the site of absorption to their intended site of action (target site) by the bloodstream, either dissolved in the serum or bound to plasma proteins. Binding to plasma proteins influences (i.e. limits or favours), drug distribution through the body. Usually it is the unbound drug concentration that determines its pharmacological and toxicological properties. Our ability to design suitable drug candidates depends on our ability to understand the molecular characteristics of drug-protein binding and ideally be able to predict the extent of binding in vivo. Here we review the different approaches that have been used to model and predict the binding of drugs and drug like molecules to plasma proteins in the body.

Protein-Drug Binding: Determination Methods
Indirect methods involve isolating the bound drug from its free form in biological samples such as blood, serum, or plasma. These techniques aim to measure the percentage of drugs bound to proteins. Equilibrium dialysis is a commonly used method where the free drug concentration at equilibrium is measured by separating the bound...

Factors Affecting Protein-Drug Binding: Drug-Related Factors
One crucial factor in drug-protein binding is the drug's lipophilicity or its affinity for fat. More lipophilic drugs tend to have higher binding extents. For example, highly lipophilic drugs like cloxacillin exhibit substantial protein binding, with as much as 95% of the drug binding to proteins. In...
