The elimination rate constant is approximated by the average of instantaneous rates over a finite period of time. The value is calculated as the negative slope of the non-weighted least squares curve fit for the logarithmically transformed concentration data versus time data (1). The formula to calculate the elimination rate constant is as follows:
