Drug interactions with digoxin are important because of this agent's narrow therapeutic index. Among the drugs that can decrease digoxin bioavailability are cholestyramine, antacid gels, kaolin-pectate, certain antimicrobial drugs and cancer chemotherapeutic agents. In selected patients, antibiotics may enhance digoxin bioavailability by eliminating intestinal flora that metabolize digoxin. Ant...
BACKGROUND In recent years, digoxin use has been on the decline, with decreased incidence of digoxin toxicity. Hence, digoxin toxicity, when it occurs, remains an elusive diagnosis to emergency physicians. OBJECTIVE To present a case of digoxin toxicity with normal levels of digoxin and serum potassium, but with severe hypomagnesemia. CASE REPORT A 66-year-old woman presented with junctiona...
Intact sheep antidigoxin antibodies and their Fab fragments have both been found to exert profound effects on digoxin pharmacokinetics in [3H] digoxin-treated dogs. Both classes of molecule remove digoxin from the extravascular space and sequester it in the circulation in protein-bound form, a form in which the digoxin is presumably inactive. These two classes of molecule differ, however, in th...
The most common methods for measuring digoxin concentrations in serum are immunoassays. The prerequisite for exact determination of the digoxin value is an antibody that specifically binds digoxin. Because digitoxin differs from digoxin only in the C-12 hydroxy group, it is difficult to obtain anti-digoxin antibodies that do not cross-react with this compound. During the development of a fluore...
Digoxin determined in the Abbott "TDx" by fluorescence polarization immunoassay by the manufacturer's recommended method involving precipitation of protein with 5-sulfosalicylic acid (SSA) is subject to interference from endogenous compounds having digoxin-like immunoreactivity. Guided by the work of Graves et al. (Clin Chem 1986;32:1506-9), we eliminated interference caused by digoxin-like imm...
Elimination of endogenous digoxin-like immunoreactive factors (DLIF) that interfere with accurate measurement of digoxin requires use of a highly specific anti-digoxin antibody, or that DLIF be separated from digoxin before immunoassay. Several commercial digoxin-assay kits include a step for separating serum proteins and other substances from digoxin before immunoassay. We tested six different...
The purpose of this study was to determine if there is a linear relationship between oral doses of digoxin and various measurements of steady-state digoxin plasma concentration and urinary excretion in patients with wide range of renal function. Ten patients (mean age 58 years) with creatinine clearances greater than 50 ml/min/1.73 m2 BSA (mean creatinine clearance 80 ml/min/1.73 m2 BSA) and ni...
PURPOSE Digoxin, a major medication for heart disease, was recently reported to have immunosuppressive capacity. Here, we determined the immunosuppressive capacity of digoxin on the development of experimental autoimmune uveitis (EAU) and on related immune responses. METHODS The B10.A mice were immunized with interphotoreceptor retinoid-binding protein (IRBP) and were treated daily with digox...
Nov 6, 2016. The amiodarone digoxin interaction is one that every pharmacist should know. Here's what to expect along with a few other clinical pearls. Amiodarone-digoxin interaction: clinical significance, time course of development , potential pharmacokinetic mechanisms and therapeutic implications. Amiodarone is known to raise serum digoxin levels. This study was designed to evaluate the pha...
Introduction & Objective:Cardiac glycosids are the oldest drugs in congestive heart failure. Digoxin one of this class drugs has widespread use Today. Because the therapeutic index of this drug is small, the change in kintic of drug induce change in serum level of drug and can be dangerous. The aim of this study was evaluation of serum level of digoxin in hospitalized patients. Materials & Met...
