• congestive heart f
  • The Prospective Randomized study Of Ventricular failure and the Efficacy of Digoxin (PROVED) trial assessed the effect of digoxin withdrawal in patients with mild to moderate congestive heart failure and sinus rhythm, and the Randomized Assessment of Digoxin on Inhibitors of Angiotensin-Converting Enzyme (RADIANCE) study had the same design and patient characteristics with the exception of patients being on concomitant ACEi therapy. (oncologynurseadvisor.com)
  • The results published in 1997 revealed that after 3 years of follow up, when digoxin was added to an ACEi-based protocol for symptomatic congestive heart failure and sinus rhythm with left ventricular ejection fraction below 45%, there was no statistically significant mortality differences between treatment and control group but hospitalization for worsening heart failure and all-cause hospitalizations were significantly diminished in the digoxin group. (oncologynurseadvisor.com)
  • Because other therapies have shown a mortality benefit in congestive heart failure, maximizing other therapies (e.g., beta blockers) first is recommended before using digoxin. (wikipedia.org)
  • serum
  • This is followed by a much more gradual decline in the serum concentration of the drug, which is dependent on the elimination of digoxin from the body. (nih.gov)
  • The digoxin receptor sites are located in the peripheral compartment, and the high degree of tissue binding means that equilibrium drug concentrations in cardiac tissue are 15-30 times those in serum. (southend.nhs.uk)

  • nausea
  • Spurious use of digoxin as a weight loss drug has been reported, presumably driven by its side effect of anorexia and nausea. (oncologynurseadvisor.com)
  • While IV therapy may be better tolerated (less nausea), digoxin has a very long distribution half-life into the cardiac tissue, which will delay its onset of action by a number of hours. (wikipedia.org)

  • heart failure
  • Digoxin is prescribed to alleviate some symptoms of heart failure. (labtestsonline.org)
  • More recently digoxin has been vanishing from our heart failure treatment protocols. (oncologynurseadvisor.com)
  • For example, in the SOLVD study of enalapril done in the late 1980s and published in 1991 about 67% of participants were concomitantly on digoxin compared to 27% in Eplerenone in Mild Patients Hospitalization and Survival Study in Heart Failure (EMPHASIS-HF) and 22% in Systolic Heart Failure Treatment (SHIFT), which were recently completed. (oncologynurseadvisor.com)
  • Older patients with AF also often have heart failure, and digoxin is approved to treat both conditions. (redorbit.com)
  • Heart failure is the only other condition for which digoxin is used, so many of the patients who continued digoxin in the AF clinical trial also had heart failure," said Ali Ahmed, M.D., professor in the divisions of Gerontology, Geriatrics, & Palliative Care and Cardiovascular Disease within the School of Medicine at the University of Alabama at Birmingham (UAB), and the new study's senior author.

  • renal
  • There is wide ranging clinical response for a given digoxin concentration and routine monitoring in patients on long- term therapy has little relevance unless renal function is changing or interacting drugs (e.g. quinidine or verapamil) are added or withdrawn. (southend.nhs.uk)
  • Digoxin elimination is predominately renal and half-life is prolonged in patients with impaired renal function. (southend.nhs.uk)
  • Quinidine, verapamil, and amiodarone increase plasma levels of digoxin (by displacing tissue binding sites and depressing renal digoxin clearance), so plasma digoxin must be monitored carefully when coadministered. (wikipedia.org)
  • thiazide
  • High calcium levels can ultimately affect body fluid levels and heart function as well, so a thiazide drug interaction with digoxin warrants observation of calcium levels. (livestrong.com)
