is bypassing enterohepatic recirculation

Question

disadvantage of oral route of administration

Answer 1

Bypassing enterohepatic recirculation can be a disadvantage of the oral route of administration in certain cases.

Enterohepatic recirculation is the process by which drugs that are metabolized and excreted by the liver are reabsorbed from the intestines back into the bloodstream, allowing for further metabolism and prolonging the drug's effect in the body. This process can be advantageous as it can increase the drug's bioavailability and enhance its therapeutic effects.

However, in some cases, bypassing enterohepatic recirculation may be desirable. For example, if a drug has a high degree of liver metabolism, bypassing this process can prevent excessive metabolism and enhance the drug's systemic availability. Additionally, if a drug undergoes significant enterohepatic recycling and there is a concern for toxicity due to accumulation, bypassing this process can help reduce the overall drug exposure and potential side effects.

In summary, while bypassing enterohepatic recirculation can be a disadvantage of the oral route of administration in terms of reducing drug availability and effects, it can also be advantageous in specific situations to enhance drug systemic availability and reduce potential toxicity.
