WebThe most important plasma proteins in this context are albumin, acid-glycoprotein and beta-globulin. Once a drug has been absorbed into the circulation it may become attached (we say bound) to plasma proteins. However this binding is rapidly reversible and non-specific – that is many drugs may bind to the same protein. WebMany acidic drugs (eg, warfarin, aspirin) are highly protein-bound and thus have a small apparent volume of distribution. Many basic drugs (eg, amphetamine , meperidine ) are extensively taken up by tissues and thus have an apparent volume of distribution larger …

Only the unbound fraction of the drug undergoes metabolism in the liver and other tissues. As the drug dissociates from the protein, more and more drug undergoes metabolism. Changes in the levels of free drug change the volume of distribution because free drug may distribute into the tissues leading to a decrease in plasma concentration profile. For the drugs which rapidly undergo metabolism, clearance is dependent on the hepatic blood flow. For drugs which slowly undergo m… polymer clay australia
