Tobramycin
別名: Nebcin, TOBI, Brulamycin, Gernebcin, Mytobrin, Tobrex
Tobramycin is a powerful antibiotic reserved for serious infections. Because of its strength, it requires careful monitoring to ensure your pet's safety. * **Administration:** If you are instructed to give subcutaneous (under the skin) injections at home, ensure you understand the exact technique and dosing schedule. Never give more than prescribed. * **Potential Risks:** This medication carries a risk of causing **kidney damage** and **hearing or balance problems** (ototoxicity). * **What to Watch For:** Contact your veterinarian immediately if you notice any of the following: * Changes in urination (drinking more, urinating more, or urinating less) * Loss of balance, stumbling, head tilt, or abnormal eye movements * Apparent hearing loss or unresponsiveness to sounds * Lethargy, vomiting, or loss of appetite * **Follow-up:** Keep all appointments for blood and urine tests. These tests are crucial to catch early signs of kidney stress before permanent damage occurs.
劑量必須由獸醫按你寵物的個別情況決定。切勿在沒有獸醫指導下給予人類藥物或其他寵物的處方藥。

給藥方式
可能的副作用
- Nephrotoxicity (acute tubular necrosis)
- Ototoxicity (vestibular and auditory damage, potentially irreversible)
- Neuromuscular blockade
- Facial edema
- Pain or inflammation at the injection site
- Peripheral neuropathy
- Hypersensitivity reactions
- Rarely: GI signs, hematologic, and hepatic effects
- Ototoxicity (vestibular and auditory damage)
- Neuromuscular blockade (rare)
注意事項與禁忌
- Known hypersensitivity to aminoglycosides
- Rabbits and hares (causes fatal disruption of GI flora)
- Pre-existing severe renal disease (unless benefits outweigh risks)
- Dehydration
- Corneal ulceration (specifically for ophthalmic preparations)
- **Extreme Caution Required:** * **Renal Impairment:** Use with extreme caution in patients with preexisting renal disease. Dosage intervals must be extended, and therapeutic drug monitoring is highly recommended. * **Risk Factors:** Neonatal and geriatric patients, fever, sepsis, and dehydration significantly increase the risk of toxicity. * **Working Dogs:** Use cautiously in working dogs (e.g., seeing-eye, herding, hearing-assistance dogs) due to the risk of irreversible ototoxicity (deafness or vestibular dysfunction). * **Neuromuscular Disorders:** Avoid or use with extreme caution in patients with myasthenia gravis or other neuromuscular disorders due to the drug's neuromuscular blocking activity. * **Feline Sensitivity:** Cats appear to be particularly sensitive to the vestibular toxic effects of aminoglycosides.
藥物相互作用
- Beta-lactam antibiotics (penicillins, cephalosporins): Synergistic antibacterial effects in vivo; however, can cause physical inactivation of aminoglycosides if mixed in the same syringe or IV line, or in vivo in patients with severe renal failure.
- Cephalosporins: Potential for additive nephrotoxicity (historically documented with older generation cephalosporins like cephalothin).
- Loop Diuretics (furosemide, torsemide): Increased risk of nephrotoxicity and ototoxicity.
- Osmotic Diuretics (mannitol): Increased risk of nephrotoxicity and ototoxicity.
- Other Nephrotoxic Drugs (cisplatin, amphotericin B, polymyxin B, vancomycin): Significantly increased risk of acute kidney injury.
- Neuromuscular Blocking Agents & General Anesthetics: Concomitant use can potentiate and prolong neuromuscular blockade, potentially leading to respiratory paralysis.
- Amphotericin B: Increased risk of nephrotoxicity
- Furosemide: Increased risk of ototoxicity and nephrotoxicity
- Heparin: In vitro chemical inactivation if mixed
- Pancuronium: Enhanced non-depolarizing neuromuscular blockade
