Therefore, we have attempted to predict digoxin serum concentration in 62 patients with a wide range of body weight, age and renal function, using creatinine clearance and individual digoxin dose. Creatinine clearance in each patient was determined by the Cockroft and Gault method (1). Digoxin clearance was determined by Scheiner's method (2). Once digoxin clearance was determined, the predicted steady-state serum concentration was calculated using general pharmacokinetic principles. Each patient was on digoxin therapy for at least 1 month. Digoxin serum concentration was measured by the newly developed fluorescence polarization immunoassay (FPIA). A linear regression analysis was performed on the data from the predicted and measured serum level which yielded a slope of 0.9463, intercept of 0.0950 and a correlation coefficient (r) of 0.9600. The method was found to be very useful to predict digoxin serum levels in overdosed and underdosed patients  ISSN : 1365-2710  Journal Name : Journal of Clinical Pharmacy and Therapeutics  Volume : 13  Issue Number : 2  Publishing Year : 1408 AH 1988 AD  Article Type : Article  Added Date : Wednesday, March 30, 2011  Researchers Researcher Name (Arabic) Researcher Name (English) Researcher Type Dr Grade Email أسامة طيب Tayeb, Osama Investigator Doctorate   سميرة اسلام Islam, Samira Researcher Doctorate   Files File Name Type Description  29427.pdf pdf   Back To Researches Page
