Insights

Drug-induced liver injury (DILI) poses a significant challenge in drug development. Understanding DILI

Area of Science:

  • Hepatology
  • Toxicology
  • Pharmacology

Background:

  • Drug-induced liver injury (DILI) affects millions annually and is a major cause of drug candidate failure.
  • Understanding DILI's biological mechanisms is crucial for minimizing its future prevalence.
  • Toxicity and safety concerns are the second-leading reason for drug candidate attrition.

Purpose of the Study:

  • To review analytical techniques for characterizing and investigating DILI mechanisms.
  • To discuss omics-based approaches for deeper biological insight into DILI.
  • To explore potential predictive biomarkers for DILI.

Main Methods:

  • Review of qualitative and quantitative analytical techniques.
  • Discussion of in vitro and multiplexed assays for DILI characterization.
  • Exploration of omics-based techniques (genomics, transcriptomics, proteomics, metabolomics).

Main Results:

  • In vitro and multiplexed assays characterize drug hepatotoxicity and DILI association.
  • Omics techniques provide qualitative and quantitative insights into DILI mechanisms.
  • Omics reveal genetic susceptibilities, gene expression changes, and protein/metabolite abundance alterations.

Conclusions:

  • Analytical techniques, especially omics, are vital for understanding DILI mechanisms.
  • Characterizing DILI through various assays aids in drug development.
  • Identifying predictive biomarkers can help mitigate DILI risks.

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

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: Drug Dosing and Hepatic Blood Flow

Chronic liver disease significantly impacts drug metabolism due to alterations in hepatic blood flow and enzyme accessibility. This disruption affects the body's pharmacokinetics—the movement and processing of drugs within the system. Key enzymes crucial for metabolizing medications become less accessible, changing how drugs are processed and utilized. Furthermore, liver disease influences the synthesis of plasma proteins, such as albumin and globulins, which play critical roles in drug...

Effect of Hepatic Disease on Pharmacokinetics: Active Drug, Metabolite and Fraction of Metabolized Drug

In pharmacotherapy, monitoring drug concentrations is paramount, especially for drugs whose therapeutic effects hinge on both the active compound and its metabolite. Hepatic impairment profoundly influences drug potency by altering liver function. If the drug is more potent than its metabolite, impaired liver function amplifies drug activity due to elevated drug concentration levels. Conversely, if the metabolite holds greater potency, diminished liver function diminishes drug activity by...

Drug Discovery: Overview

Drug discovery is a multifaceted process involving extensive screening, testing, and optimization of lead compounds to identify potential new drugs for therapeutic use. It combines several approaches, including screening large numbers of natural products, chemical modification of known active molecules, identification of new drug targets, and rational design based on biological mechanisms and drug-receptor structure. These approaches are carried out in both academic research laboratories and...

Drug Biotransformation: Overview

Pharmaceutical substances known as xenobiotics are predominantly lipophilic and nonionized. This enables them to permeate lipid bilayers, such as cell membranes, and interact with intracellular target receptors. Lipophilic drugs have an advantage in crossing biological barriers and reaching their intended sites of action. However, lipophilic drugs often have a restricted capacity for renal expulsion or elimination from the body. When these drugs enter the kidneys and undergo glomerular...

Drug Biotransformation: Overview01:28

Drug Biotransformation: Overview

Biotransformation, also known as drug metabolism, is a vital physiological process that chemically alters drugs, facilitating their elimination from the body and terminating their action. This process involves two main phases: phase I and phase II reactions. Phase I reactions, including oxidation, reduction, and hydrolysis, introduce or unmask polar functional groups on the drug molecule, thereby increasing its water solubility. By enhancing water solubility, the drug becomes more hydrophilic...
