WebMany drugs bind to proteins, primarily albumin, alpha-1 acid glycoprotein, and lipoproteins; protein binding limits distribution of free drug throughout the body. Albumin and total protein concentrations are lower in neonates but approach adult levels by 10 to 12 months. Decreased protein binding in neonates is also due to qualitative differences in binding … WebExamining the important but transient ligand–protein-bound conformations, in addition to experimentally determined structures, also provides a more accurate estimation for drug efficacy and ...

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…
