In cases of those drugs, which has high first-pass effect, oral administration is avoided, to get the desired effect. A significant issue of concern with the first pass effect is taking into account its variability among different individual patients. The first pass effect also has an impact on peak drug concentrations, which may result in drug concentration peaks occurring much earlier than they would in a parenteral dose. It is please click for source important that pharmacological dosing considers these natural variations in human metabolism to ensure patients remain within the therapeutic window of the appropriate drug.
