Changes in drug metabolism with increasing age: 1. warfarin binding and plasma proteins. 1975

M J Hayes, and M J Langman, and A H Short

1 A decrease was found in the binding capacity of elderly people for warfarin. 2 The decrease in binding correlated with a fall in plasma albumin concentrations. 3 No changes in the association constant were observed.

D011485 Protein Binding The process in which substances, either endogenous or exogenous, bind to proteins, peptides, enzymes, protein precursors, or allied compounds. Specific protein-binding measures are often used as assays in diagnostic assessments. Plasma Protein Binding Capacity,Binding, Protein

D000328 Adult A person having attained full growth or maturity. Adults are of 19 through 44 years of age. For a person between 19 and 24 years of age, YOUNG ADULT is available. Adults
D000368 Aged A person 65 years of age or older. For a person older than 79 years, AGED, 80 AND OVER is available. Elderly
D000375 Aging The gradual irreversible changes in structure and function of an organism that occur as a result of the passage of time. Senescence,Aging, Biological,Biological Aging
D012709 Serum Albumin A major protein in the BLOOD. It is important in maintaining the colloidal osmotic pressure and transporting large organic molecules. Plasma Albumin,Albumin, Serum
D014859 Warfarin An anticoagulant that acts by inhibiting the synthesis of vitamin K-dependent coagulation factors. Warfarin is indicated for the prophylaxis and/or treatment of venous thrombosis and its extension, pulmonary embolism, and atrial fibrillation with embolization. It is also used as an adjunct in the prophylaxis of systemic embolism after myocardial infarction. Warfarin is also used as a rodenticide. 4-Hydroxy-3-(3-oxo-1-phenylbutyl)-2H-1-benzopyran-2-one,Aldocumar,Apo-Warfarin,Coumadin,Coumadine,Gen-Warfarin,Marevan,Tedicumar,Warfant,Warfarin Potassium,Warfarin Sodium,Potassium, Warfarin,Sodium, Warfarin
