Effect of Hepatic Disease on Pharmacokinetics: Pathophysiologic Assessment and Liver Function Test

10
In clinical practice, the direct measurement of hepatic blood flow to evaluate liver function presents significant challenges due to the intricate and specialized nature of the necessary techniques. Consequently, healthcare professionals often rely on empirical estimates derived from thorough patient examinations and liver function tests to gauge liver health. Among the tools at their disposal, the Child–Pugh and MELD scoring systems stand out for their ability to categorize and assess...

Effect of Hepatic Disease on Pharmacokinetics: Dose Adjustments Due to Hepatic Impairment

8
Hepatic impairment, characterized by decreased liver function, does not uniformly mandate adjustments in drug dosage. Whether dosage modifications are necessary depends on various factors related to the drug's metabolism and elimination pathways. If a drug is primarily excreted via the kidneys and bypasses significant hepatic processing, if it undergoes minimal metabolic transformation in the liver, or if it is volatile and primarily expelled through the lungs, dose adjustments may not be...

Area of Science:

  • Oncology
  • Hepatology
  • Pharmacology

Background:

  • Immune-mediated drug-induced liver injury (DILI) is a significant concern with various medications, including immunotherapies.
  • Olaparib, a poly (adenosine diphosphate-ribose) polymerase (PARP) inhibitor, is utilized in treating specific ovarian cancers with BRCA mutations.

Observation:

  • This report details the first documented case in the United States of acute and severe liver injury linked to olaparib.
  • The patient presented with jaundice and impaired liver synthetic function, indicative of significant hepatotoxicity.

Findings:

  • Cessation of olaparib led to the resolution of the drug-induced liver injury.
  • Treatment with a prednisone taper further supported the recovery of liver function.

Implications:

  • This case underscores the potential for olaparib to cause severe hepatotoxicity, necessitating vigilant liver function monitoring in patients undergoing treatment.
  • Awareness of this adverse effect is crucial for oncologists and hepatologists managing patients on olaparib therapy.
  • Early recognition and intervention, including drug withdrawal and corticosteroid treatment, can effectively manage olaparib-induced liver injury.
