A significant issue of concern with the first pass effect is taking into account its variability among different individual patients.
It is incredibly important that pharmacological dosing considers these natural variations in human metabolism to ensure patients remain within the therapeutic window of the appropriate drug. The clinical significance of the first pass effect is crucial to the proper administration and maintenance of pharmacological therapy. Some drugs that undergo considerable first-pass metabolism include alprenolol, 5-fluorouracil, morphine, pentazocine, and mercaptopurine. When given orally, these drugs are quickly metabolized via the first-pass effect, requiring their oral dosages to be much larger than their intravenous dosages. 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.
