Renal digoxin clearance: dependence on plasma digoxin and diuresis. 1982

E Steiness, and S Waldorff, and P B Hansen

The renal handling of digoxin in animals involves glomerular filtration, tubular secretion and tubular reabsorption, while only glomerular filtration and tubular secretion have been described in humans. The influence of plasma digoxin and urine flow on the renal handling of digoxin was investigated in 6 healthy volunteers. Non-glomerular renal excretion of digoxin (tubular secretion minus tubular reabsorption) was inversely correlated with plasma digoxin concentration and directly with urine flow. Hence, the present study demonstrated the occurrence of tubular reabsorption in addition to glomerular filtration and tubular secretion of digoxin. The results suggest that renal clearance of digoxin should be increased by increased urine flow, which might be of importance during digoxin toxicity.

UI MeSH Term Description Entries
D007684 Kidney Tubules Long convoluted tubules in the nephrons. They collect filtrate from blood passing through the KIDNEY GLOMERULUS and process this filtrate into URINE. Each renal tubule consists of a BOWMAN CAPSULE; PROXIMAL KIDNEY TUBULE; LOOP OF HENLE; DISTAL KIDNEY TUBULE; and KIDNEY COLLECTING DUCT leading to the central cavity of the kidney (KIDNEY PELVIS) that connects to the URETER.

D004077 Digoxin A cardiotonic glycoside obtained mainly from Digitalis lanata; it consists of three sugars and the aglycone DIGOXIGENIN. Digoxin has positive inotropic and negative chronotropic activity. It is used to control ventricular rate in ATRIAL FIBRILLATION and in the management of congestive heart failure with atrial fibrillation. Its use in congestive heart failure and sinus rhythm is less certain. The margin between toxic and therapeutic doses is small.
