Is there a role for digoxin in atrial fibrillation without heart failure?
ABSTRACT Digoxin remains one of the most frequently prescribed drugs in the management of atrial fibrillation. The main indications for digoxin in atrial fibrillation are restoration of sinus rhythm, prevention of recurrence and slowing of the ventricular rate. However, none of these effects of digoxin have been confirmed in placebo controlled studies. In addition, recent reports suggest increased mortality in patients with atrial fibrillation without heart failure taking digoxin. The aim of this article is to review the role of digoxin in atrial fibrillation without heart failure.

ABSTRACT: In addition to being valuable source of energy, carbohydrates, one of the main dietary components, are integral parts of the cell. As extra- & intracellular molecules they act as cell surface receptor and also as signaling molecules playing predominant role in molecular recognition and many other cellular processes. The clear understanding of their role in the various important biological events has led to the demand for easy access of diverse glycoconjugates for their complete chemical and biological investigations. Several carbohydrate-based molecules both of synthetic and natural origin are known for their wide range of pharmacological activities and even many of them are clinically used to treat different ailments. Due to their structural diversity in terms of functional groups, ring size and linkages they are valuable scaffolds in drug discovery processes. Because of the hydrophilic nature of monosaccharides they offer good water solubility, optimum pharmacokinetics and decreased toxicity. These naturally occurring molecules have therefore been extensively used to access diverse library of compounds with great chemotherapeutic importance. This review highlights an overview of development of carbohydrate-based molecules from others and our lab which have shown promising biological activity against front line diseases.Mini Reviews in Medicinal Chemistry 06/2012; DOI:10.2174/138955712803832654 · 3.19 Impact Factor
