The data base for rational guidelines to safe, efficacious drug prescribing in adults with renal insufficiency are presented in tabular form. Current medical literature was extensively surveyed to provide as much specific information as possible. When information is lacking, however, recommendations are based on pharmacokinetic variables in normal subjects.(More)
Fluoxetine (30 mg), administered for 7 days to normal volunteers, produced a 66% inhibition of tritiated serotonin uptake into platelets. Plasma concentrations of fluoxetine correlated positively with inhibition of serotonin uptake. Fluoxetine is well absorbed after oral administration in both the fed and fasted states and demonstrates dose proportionality.(More)
The effect of decreased renal function on the disposition and elimination of the nontricyclic antidepressant fluoxetine was examined in 25 adult male subjects after a single 40-mg oral dose. Blood samples for the measurement of fluoxetine and its active metabolite norfluoxetine were drawn 13 times in the first 48 hr after dosing and thrice weekly thereafter(More)
Hemoglobin levels in individuals with chronic kidney disease fluctuate frequently above or below the recommended target levels within short periods of time even though the calculated mean hemoglobin remains within the target range of 11 to 12 g/dl. Both pharmacologic features and dosing of erythropoiesis-stimulating agents may lead to cyclic pattern of(More)
Drug dosage adjustment for patients with acute or chronic kidney disease is an accepted standard of practice. The challenge is how to accurately estimate a patient's kidney function in both acute and chronic kidney disease and determine the influence of renal replacement therapies on drug disposition. Kidney Disease: Improving Global Outcomes (KDIGO) held a(More)
Increased serum iodide concentrations secondary to iodine absorption through wounds treated with povidone-iodine dressings is described. Hyperchloremic acidosis and a disparity between serum chloride concentrations determined by two different methods suggested the presence of an unidentified halide. Cardiovascular instability and renal failure occurred(More)
BACKGROUND AND OBJECTIVES Anemia management protocols in ESRD call for hemoglobin (Hb) monitoring every 2 to 4 weeks. Short-term Hb variability affects the reliability of Hb measurement and may lead to incorrect dosing of erythropoiesis stimulating agents. We prospectively analyzed short-term Hb variability and quantified the relationship between frequency(More)
Linezolid is a member of a new, unique class of synthetic antibacterial agents called oxazolidinones that are effective against gram-positive bacteria, including vancomycin-resistant organisms. We tested the hypothesis that the linezolid clearance would not be altered in subjects with renal dysfunction. Twenty-four subjects with renal function that ranged(More)
To test the hypothesis that renal failure alters the absorption and metabolism of nitrendipine and the renal elimination of its metabolites, we gave six normal men and 16 men with various degrees of renal dysfunction a single 20 mg oral dose of nitrendipine. Plasma nitrendipine and nitrendipine pyridine analog metabolite concentrations were measured by HPLC(More)
Optimizing anemia management is the sole indication for intravenous (IV) iron administration in the patient with chronic kidney disease (CKD): Achieving and maintaining iron sufficiency is crucial to achieving and maintaining target-range hemoglobin (Hgb). Although pica (geophagia) (1) and restless legs syndrome (2,3) may arise in iron-deficient patients,(More)
