Concurrent use of neuromuscular blocking agents; conditions predisposing to ototoxicity and nephrotoxicity; lactation. Monitor plasma concentrations of gentamicin in patients receiving high doses or prolonged courses, in infants, elderly, patients with renal impairment, cystic fibrosis or significant obesity. Monitor auditory and renal functions.
Lactation: excreted in breast milk; no adverse effect on nursing infant
Indication
Bacterial skin infections, Burns, eczema, seborrheic dermatitis, ecthyma, excoriation, folliculitis, furunculosis, insect bites and stings, lacerations and abrasions, paronychia, pyoderma gangrenosum, skin cysts and abscesses, stasis ulcers and infected skin ulcers, bacterial, fungal or viral superinfection, sycosis barbae, minor surgical wounds, infected contact dermatitis caused by susceptible organisms.
Contra Indication
History of hypersensitivity to aminoglycoside; pregnancy; hepatic impairment, skin rash.
Dose
N/A
Side Effect
Allergic contact dermatitis, Erythema, Pruritus
Pregnancy Category
Name :
C
Description
Animal reproduction studies have shown an adverse effect on the fetus and there are no adequate and well-controlled studies in humans, but potential benefits may warrant use of the drug in pregnant women despite potential risks
Mode of Action
Gentamicin is an aminoglycoside that binds to 30s and 50s ribosomal subunits of susceptible bacteria disrupting protein synthesis, thus rendering the bacterial cell membrane defective.
Interaction
Synergistic with ampicillin, benzylpenicillin and other beta-lactam antibiotics. Increased risk of severe respiratory depression when used concurrently with anaesthetics or opioids. May reduce renal clearance of zalcitabine and induce hypocalcaemia when used with biphosphonates. Not to be used with agalsidase alfa or beta as it may inhibit alpha-galactosidase activity.
Potentially Fatal: Increased incidence of ototoxicity when combined with ethacrynic acid and furosemide. Cephalosporins, ciclosporin, cisplatin, vancomycin, hydrocortisone and indometacin potentiate nephrotoxicity. Potentiates neuromuscular blocking agents.
