The purpose of this study is to find out how chemicals in the blood of patients with chronic kidney disease affect how medications are removed from the body. The patient will take one dose of three different drugs, one on each week, for a total of three single doses. The investigators want to find out if these three different medications are affected in different ways by the chemicals in the blood of patients with kidney disease.
It has been demonstrated that proteins known as drug transporters in different human organs and tissues are important for a drug to be absorbed, distributed, metabolized, and eliminated (ADME)18. The chemical properties of drugs can affect whether it needs a transporter protein to enter the cell or not. It is not well known how these proteins are affected in chronic disease and how different drugs may be absorbed, metabolized, or eliminated differently in certain diseases. Preliminary studies suggest that some drugs (those requiring drug transporter proteins) may show altered elimination in the presence of uremic toxins. Uremic toxins are substances accumulated in the blood of patients with chronic kidney disease and many are not removed through hemodialysis (HD). We hypothesize that the different classes of drugs (BDDCS class1, 2, and 3) will have different degrees of changes in AUC, meaning that for a class 1 drug we would see less of a change in AUC than in a class 3 drug because a class 3 drug requires transporters. Previous studies can't make that comparison because they used different patients for each drug, so even if there were a change in a class 1 drug, it can't be compared to a class 3 drug. In order to get an accurate comparison, we will test the three drugs on the same patient and see how he AUC changes from drug to drug within the same patient comparing it to the healthy volunteer (taking the same three drugs).

Conditions in which the KIDNEYS perform below the normal level for more than three months. Chronic kidney insufficiency is classified by five stages according to the decline in GLOMERULAR FILTRATION RATE and the degree of kidney damage (as measured by the level of PROTEINURIA). The most severe form is the end-stage renal disease (CHRONIC KIDNEY FAILURE). (Kidney Foundation: Kidney Disease Outcome Quality Initiative, 2002)
The end-stage of CHRONIC RENAL INSUFFICIENCY. It is characterized by the severe irreversible kidney damage (as measured by the level of PROTEINURIA) and the reduction in GLOMERULAR FILTRATION RATE to less than 15 ml per min (Kidney Foundation: Kidney Disease Outcome Quality Initiative, 2002). These patients generally require HEMODIALYSIS or KIDNEY TRANSPLANTATION.
A complication of kidney diseases characterized by cell death involving KIDNEY PAPILLA in the KIDNEY MEDULLA. Damages to this area may hinder the kidney to concentrate urine resulting in POLYURIA. Sloughed off necrotic tissue may block KIDNEY PELVIS or URETER. Necrosis of multiple renal papillae can lead to KIDNEY FAILURE.
An autoimmune disease of the KIDNEY and the LUNG. It is characterized by the presence of circulating autoantibodies targeting the epitopes in the non-collagenous domains of COLLAGEN TYPE IV in the basement membranes of kidney glomeruli (KIDNEY GLOMERULUS) and lung alveoli (PULMONARY ALVEOLI), and the subsequent destruction of these basement membranes. Clinical features include pulmonary alveolar hemorrhage and glomerulonephritis.
KIDNEY injuries associated with diabetes mellitus and affecting KIDNEY GLOMERULUS; ARTERIOLES; KIDNEY TUBULES; and the interstitium. Clinical signs include persistent PROTEINURIA, from microalbuminuria progressing to ALBUMINURIA of greater than 300 mg/24 h, leading to reduced GLOMERULAR FILTRATION RATE and END-STAGE RENAL DISEASE.
Nephrology - kidney function
Nephrology is a specialty of medicine and pediatrics that concerns itself with the study of normal kidney function, kidney problems, the treatment of kidney problems and renal replacement therapy (dialysis and kidney transplantation). Systemic conditions...
