Systemic absorption of gentamicin ear drops

Abstract: Aminoglycoside-containing topical preparations are commonly used in the treatment of chronic suppurative otitis media and otitis externa. We report a case where systemic absorption of topical Gentisone HC™ occurred producing a serum gentamicin level of 6.2 μg/ml.

“…Similarly, systemic absorption of gentamicin eardrops has also been reported in literature. 9 Other risk factors contributing to increasing the susceptibility of gentamicin nephrotoxicity in our patient include dehydration, female sex, old age, and concomitant use of aminoglycoside with vancomycin. 10 In conclusion, systemic absorption of gentamicin and vancomycin eyedrops can be significant, and nephrotoxicity is possible in susceptible patients.…”

“…A maioria das gotas otológicas é formulada com associação de corticosteróides, anestésicos locais e antimicrobianos (geralmente aminoglicosídeos ou quinolonas) [3][4][5] . Seu uso por doentes com perfuração timpânica traz riscos de ototoxicidade (lesão coclear ou vestibular pelos aminoglicosídeos, por exemplo) e toxicidade sistêmica, pois as gotas podem ser absorvidas pela mucosa da orelha média ou alcançar a faringe através da tuba auditiva, sendo então deglutidas 6,7 .…”

“…We often assume that the reported ototoxic effects of preparations are solely due to round window penetration, but seeing that routine aminoglycoside levels are not measured in these patients, this must remain an assumption. In a recent case report, a 62-year-old patient with chronic renal failure was found to have a serum gentamicin level of 6.2 |xg/ml after using two Gentisone HC™ drops three times a day, for 37 days duration (Green et al, 1997).…”
