Certain medications can damage the inner ear, causing hearing loss and balance problems. Early identification of at-risk patients and monitoring are crucial for preventing severe ototoxicity.

Area of Science:

  • Ototoxicology
  • Neuroscience
  • Pharmacology

Context:

  • Dizziness and equilibrium disturbances can stem from central nervous system (CNS) dysfunction or sensory input impairment.
  • Numerous medications, including antihypertensives and antipsychotics, can cause positional hypotension.
  • This review focuses specifically on drugs with ototoxic properties, which damage the inner ear or vestibulocochlear nerve.

Purpose:

  • To review drugs with true ototoxic properties, detailing their potential to cause cochlear or vestibular damage.
  • To identify predisposing factors for ototoxicity, such as renal failure, age, and drug combinations.
  • To discuss prevention strategies, including early risk recognition and monitoring of cochleovestibular functions.

Summary:

  • Over 130 products are classified as potentially ototoxic, with antibiotics (aminoglycosides, macrolides), loop diuretics, antimalarials, and chemotherapeutics being extensively studied.

  • Individual susceptibility to ototoxicity varies, influenced by factors like age, renal function, and prior neurosensory deficits.
  • Environmental toxins and drugs of abuse also pose risks, though scientific data is less extensive.

    • Impact:

    • Ototoxicity can lead to irreversible hearing impairment and balance disturbances, significantly impacting quality of life.
    • Early detection of at-risk individuals and vigilant monitoring are essential for preventing severe, life-altering complications.
    • Understanding ototoxic mechanisms and risk factors aids in clinical decision-making and patient management.
