Cholestasis alters drug metabolism enzymes and transporters (DMETs), affecting how the body processes medications. Understanding these changes is crucial for safe and effective drug selection and dosing in patients with this liver condition.
Area of Science:
- Hepatology
- Pharmacology
- Biochemistry
Background:
- Cholestasis is a chronic liver disease impacting bile acid homeostasis.
- This condition significantly complicates drug disposition and patient treatment.
- Drug metabolism enzymes and transporters (DMETs) are critical for drug clearance.
Purpose of the Study:
- To review alterations in hepatic and extrahepatic DMETs during cholestasis.
- To focus on changes in cytochrome P450 (CYP450) and drug transporters.
- To discuss drugs that can restore DMET expression in cholestasis.
Main Methods:
- Literature review synthesizing existing research on DMETs in cholestasis.
- Analysis of studies documenting changes in DMET expression and function in rodents and humans.
- Examination of drug substrates affected by cholestasis-induced DMET modifications.
Main Results:
- Cholestasis induces significant modifications in the expression and function of key DMETs.
- Both cytochrome P450 enzymes and drug transporters are affected, altering drug metabolism.
- Changes in DMETs impact the disposition of various drug substrates.
Conclusions:
- Cholestasis profoundly affects drug disposition by altering DMETs.
- These alterations necessitate a reevaluation of drug selection and dosing strategies for cholestatic patients.
- Further research into therapeutic agents that restore DMET function is warranted.
