- ED50V10 (Readme) is an Excel add-in for calculating IC50/EC50 values. Input your data in the left columns, and your results will be shown in the right half of the Excel table. To calculate IC50, input 50 in the INTERPOLATE... table (highlighted in blue), the result will be shown on the right (highlighted in green).inear Regression. The simplest estimate of IC50 is to plot x-y and fit the data with a straight line (linear regression). IC50 value is then estimated using the fitted line, i.e., Y = a * X + b, IC50 = (0.5 - b)/a. Log transformation. Frequently, linear regression is not a good fit to dose-response data.

PHARMACIST ADVISOR: Calculating drips per minute To calculate gtt/min, follow these steps: Step 1: Convert the rate of administration from ml/hr to ml/min. 1 hour = 60 minutes, so take your number in ml/hr and divide by 60 min/hr. For example: You have an order for D5W 1000 ml over 8 hours.First, 1000 ml / 8 hr = 125 ml/hr; 125 ml/hr / 60 min = 2.08 ml/min.Math tip: use conversions in which the units cancel to find your answer: hour = 60 minutes, so take your number in ml/hr and divide by 60 min/hr. For example: You have an order for D5W 1000 ml over 8 hours. First, 1000 ml / 8 hr = 125 ml/hr; 125 ml/hr / 60 min = 2.08 ml/min.

- The concept of an absolute IC50 is not standard, and many find it not to be useful. But if you do, it is not hard to fit a curve to determine it. This EPA document, give the needed equation (which I have generalized a bit, so not require that the data already be normalized). Fifty=(Top+Baseline)/2.Y= Bottom + ....f the response plateaus at 0%, then an absolute and relative IC50 are the same, and you can just fit the usual dose-response curve to find the IC50. 2. At the bottom of the data table, add a new row of data. Enter 50 into each Y column.
