First-Pass Effect
- The 'first-pass effect' refers to the process by which the liver metabolizes a significant portion of the drug before it reaches the systemic circulation, reducing the bioavailability of the drug.
Disadvantages of Oral Route
- A significant disadvantage of the oral route is that it can result in unpredictable drug absorption due to variations in gastric emptying time, pH, and the presence of food or other substances in the GI tract.
