Insights

Drug-induced hearing loss, or ototoxicity, can permanently damage hearing, especially in children. This review details ototoxic drugs, their mechanisms, and strategies for prevention and early detection.

Area of Science:

  • Ototoxicology
  • Pharmacology
  • Audiology

Background:

  • Drug ototoxicity significantly impacts patient quality of life, with severe psychosocial implications for children.
  • While some drug-induced ototoxicity is reversible, platinum derivatives and aminoglycosides are known to cause permanent hearing loss.

Purpose of the Study:

  • To review and list drugs known to cause ototoxicity.
  • To elucidate the mechanisms by which these drugs damage auditory structures.
  • To discuss protective strategies and early detection methods for ototoxic effects.

Main Methods:

  • Literature review of ototoxic drugs and their effects.
  • Analysis of mechanisms underlying drug-induced ototoxicity.
  • Compilation of current protective and diagnostic approaches.

Main Results:

  • Identification of key ototoxic drug classes, including platinum derivatives and aminoglycosides.
  • Detailed explanation of cellular and molecular mechanisms of ototoxicity.
  • Overview of potential interventions and monitoring techniques.

Conclusions:

  • Understanding ototoxic mechanisms is crucial for mitigating hearing loss.
  • Proactive strategies and early detection are vital for managing drug-induced ototoxicity.
  • This review provides a comprehensive resource for clinicians and researchers.

Drug toxicity: Idiosyncratic Reactions

Idiosyncratic drug reactions represent abnormal chemical responses that vary significantly among individuals, ranging from extreme sensitivity to low doses to insensitivity to high doses. These reactions often occur due to the drug's covalent binding with serum proteins, forming a foreign hapten that triggers an immunotoxicological response. The variability in drug reactions has a strong pharmacogenetic foundation, with genetic differences crucial in how individuals metabolize drugs. For...

Pharmacogenetic Phenotypes: Alterations in Pharmacokinetics, Drug Targets and Biologic Milieu

Genetic variations significantly influence drug response through pharmacokinetics, receptor interactions, and biologic milieu modifications. Pharmacokinetic alterations impact drug metabolism and clearance, affecting efficacy and toxicity. Variants in drug-metabolizing enzymes, such as CYP2C9 and CYP2C19, alter drug activation and elimination. For example, CYP2C9 loss-of-function variants require lower warfarin doses to prevent excessive bleeding, while CYP2C19 variants reduce clopidogrel...

Drug Toxicity: Risk factors01:24

Drug Toxicity: Risk factors

Adverse Drug Reactions (ADRs) are potential complications that arise during pharmacotherapy, influenced by multiple risk factors. Age plays a significant role; both neonates and the elderly are at heightened risk due to their respective immature and diminished metabolic and elimination processes. Gender also impacts ADRs, with females experiencing a 1.5 to 1.7-fold greater risk than males, which may be linked to pharmacokinetic, pharmacodynamic, and hormonal differences. Notably, neonates, the...

Pharmacogenetics and Pharmacogenomics: Overview01:29

Pharmacogenetics and Pharmacogenomics: Overview

Pharmacogenetics and pharmacogenomics examine how genetic factors influence an individual's response to drugs. While pharmacogenetics focuses on the impact of specific genetic variants on drug effects, pharmacogenomics takes a broader approach, studying how genetic variation across populations contributes to differences in drug responses. These fields aim to explain why individuals may experience varying levels of efficacy or adverse reactions to the same medication.Variability in drug...

Drug Toxicity: Dose-Dependent Reactions

Drug toxicities can be stratified into pharmacological, pathological, or genotoxic based on their mechanisms. The incidence and severity of these toxicities generally increase with the drug's concentration in the body and exposure time.Pharmacological toxicity is evident when the therapeutic effects of drugs overshoot into adverse reactions in a predictable, dose-dependent manner. Central nervous system (CNS) depression from barbiturates is a classic example, with effects escalating from...

Pharmacogenetics of Drug Metabolism: Overview01:27

Pharmacogenetics of Drug Metabolism: Overview

Genetic polymorphism in drug metabolism is crucial to the inter-individual variability observed in drug responses. Drug metabolism primarily involves the chemical modification of drugs and other xenobiotics to enhance their elimination by increasing their polarity. Two main classes of enzymes mediate this biotransformation process: Phase I enzymes, primarily cytochrome P450s, catalyze oxidation and reduction reactions, while other enzymes, such as esterases, mediate hydrolysis, and Phase II...
