Key information summary
Efficacy & effects
This medication is used to treat infections caused by various bacteria. The injectable form is effective against a range of infections caused by harmful bacteria such as Pseudomonas aeruginosa, Escherichia coli, and Staphylococcus aureus, including meningitis, pneumonia, peritonitis, soft tissue infections, bone infections, sepsis, pyelonephritis, and cystitis. The ophthalmic solution and ointment are used to treat ocular infections such as blepharitis, dacryocystitis, stye, conjunctivitis, and keratitis caused by bacteria such as Staphylococcus and Streptococcus around the eyes. This drug helps to comprehensively improve complex bacterial infections and facilitates rapid recovery of patients.
Dosage
In severe infections, as tobramycin, 3mg (potency) per kg body weight, divided into 3 intravenous or intramuscular injections per day. In life-threatening infections, it may be administered in divided doses up to 5mg (potency) per kg body weight, and once symptoms improve, the dose should be reduced to 3mg (potency) per kg body weight. Do not exceed 5mg (potency) per kg body weight without measuring serum concentration.
Precautions
This medication should not be used in certain patients. For example, it should not be administered to patients with allergic reactions to this drug or aminoglycoside antibiotics or bacitracin, patients with ear disorders, patients with severe renal impairment, pregnant or breastfeeding women, patients with muscle disorders, patients with bronchial asthma, and patients with eighth cranial nerve disorders. When using this drug, special caution is necessary for patients with reduced renal function, impaired liver function, neonates or premature infants, elderly patients, and those with poor nutritional status. Such patients may experience more severe drug side effects, so administration should be under careful medical judgment. Rarely, when using this drug, symptoms such as shock, nausea, vomiting, loss of appetite, blood abnormalities, dizziness, tinnitus, hearing loss, liver dysfunction, worsening renal function, skin rash, and allergic reactions may occur, so if symptoms arise, it is important to inform healthcare professionals immediately. The duration of administration should be kept as short as possible, and during long-term or high-dose treatment, blood drug levels and hearing tests should be performed regularly to detect and prevent side effects early. This drug may have intensified side effects when used with other medications that affect the kidneys or have neuromuscular blocking effects, so caution is warranted when used concurrently. During pregnancy, there is a risk of causing ear damage to the newborn, so it should only be administered when absolutely necessary, and breastfeeding should be discontinued as the drug can pass into breast milk. Due to differences in renal function, children and the elderly may experience higher drug concentrations, so dosing intervals or amounts should be adjusted, and their conditions should be closely monitored. In cases of overdose, kidney damage, hearing loss, and respiratory distress may occur, so immediate hospital visit for appropriate treatment is required. In the forms of ophthalmic solution or ointment, it is applied directly to the eye, and symptoms such as eyelid itching, swelling, erythema, and transient stinging may appear; if symptoms worsen, use should be discontinued. Contact lens wearers should avoid wearing lenses during treatment, and caution should be exercised when driving or operating machinery due to possible blurred vision. Do not inject into the eye, and during instillation, take care to avoid contact between the tube tip and the eye to prevent contamination. This medication may be resistant to certain bacteria, so it is important to use it only for an appropriate duration after confirming the type and sensitivity of the infecting bacteria.
