Salicylates andNonsteroidal Anty- Inflammatory Drugs

Aspirin at high doses - typically exceedin g 6 grams per day for conditions such as reuxid artritis - frequently causes reversible tinnitus and mild hearing loss. The effect is dose- dependent and typically resolves with in days of stopping the drug.

Risk Factors for Othuricity

Impairment

Many ototoksyc drugs are eliminated renally. Impaired kidney functionion leads to prolonged drug exposure, elevating the risk of inner ear damage.

The Cockcroft- Gault equation should be used to estimate creatinine clearance and guidee dosing addicruments for renally clearid otototototothins.

Preegzystening noise- induced hearing loss or exposure to loud noise during ototoksyc therapy can synergicaly worsen damage. The combination of cisplatin chemotherapy eld loud noise exposure, for example, produces greater cochlear damage than either insult alone. Pationts on ototoksyc mediciations should d be advidexed to avoid recreational noise, use hearing protection in ocquigation al settings, and limit exposlure to personal audio devices at high volumes.

Age and- existing Hearing Loss

Very young children ande te elderly are more loweblade. Neonates have immature renal function andd reduced clearance of ototoksyc drugs, whill their ir developing audity systems are specilarly sensitivy to detult. Older diults may have age- related hearing loss that makes them less tolerant of additional cochlear presy, and presbycusis can mask early ototoksyc chances on audiometriy.

Interakcje z innymi lekami

Kombinacja dwóch or more ototoksyc agents signitantly amplifies risk. Te combination of aminoglikosides with roop diuretics, for instance, produces synergistic ototoksycyty. Certain medicators can also alter drug metabolism or extraction, potentiating ototoksycyty. Vancomycin and aminoglikosides should be used together only when n absolutely necesary andwith careful monitoring of both drug levels and audiologic function.
