Limitations in interpretation of digoxin adsorption using averaged pharmacological response intensities.
In this paper, the interpretation of averaged pharmacological effect data for the cardiac glycoside digoxin is reconsidered through a comparison with theoretically simulated data. Four parameters, with their standard deviations calculated from the best-fit biexponential equation for the experimentally derived transformed pharmacological response intensity, were the basis for the random development of a series of 17 individual sets of data with average parameters and standard deviations identical to the values found experimentally. Parameters from these 17 data sets were averaged and randomly altered as a function of the standard deviations for each average. Loo-Riegelman analyses, modified for application to the peripheral compartment, and fraction remaining to be absorbed plots were made. Results of this comparison of experimental pharmacological simulated data indicate that the presence or absence of enterohepatic recycling may not be unambiguously determined here.
