What are the clinical symptoms of ototoxicity with aminoglycosides?
The most common aminoglycoside drugs are streptomycin, gentamicin, neomycin, it’s long-term use will lead to neurological tinnitus, neurological deafness, and even memory loss, hearing loss, dizziness and other conditions.
Which antibiotics cause nephrotoxicity and ototoxicity?
The aminoglycoside antibiotic gentamicin can cause both ototoxicity and nephrotoxicity, the severity of which varies with circadian time of daily treatment. However, it is not yet resolved if such drug-induced adverse effects are independent or dependent phenomena.
What are aminoglycosides used to treat?
Aminoglycosides are used in the treatment of severe infections of the abdomen and urinary tract, as well as bacteremia and endocarditis. They are also used for prophylaxis, especially against endocarditis. Resistance is rare but increasing in frequency.
Why do aminoglycosides cause ototoxicity?
Aminoglycosides appear to generate free radicals within the inner ear, with subsequent permanent damage to sensory cells and neurons, resulting in permanent hearing loss. Two mutations in the mitochondrial 12S ribosomal RNA gene have been previously reported to predispose carriers to aminoglycoside-induced ototoxicity.
What drugs cause ototoxicity?
Ototoxic medications known to cause permanent damage include certain aminoglycoside antibiotics, such as gentamicin (family history may increase susceptibility), and cancer chemotherapy drugs, such as cisplatin and carboplatin.
What are the two major side effects of aminoglycosides?
The major side effects of aminoglycosides are kidney injury, hearing impairment and vestibular toxicity.
Can ototoxicity be cured?
Ototoxicity symptoms can be reversed when you stop taking the underlying medication, but if the condition is not treated immediately, you may suffer permanent ear damage.

Which disease is best treated with an aminoglycoside antibiotic?
Which aminoglycoside is used in TB?
Today, the aminoglycosides kanamycin and amikacin are used to treat multidrug-resistant (MDR) TB, and resistance to any of the second-line injectable antibiotics, including kanamycin, amikacin, or capreomycin, is a defining characteristic of extensively drug-resistant (XDR) TB.
