Directions

Select values for the different PK parameters by dragging the slider for each parameter to the right. The current parameter value will be displayed.

The renal excretion rate-time profile will be graphed when you click plot.

You can change the x and y scale values by clicking the Adjust scale buttons

Adjust X Scale

Enter the maximum value for the X axis. The minimum value for the X axis will be zero.

Adjust Y Scale

Enter the maximum value for the Y axis. The minimum value for the Y axis will be 1/1000 of the maximum value.
