3. Mechanism of Action: How It Works
Tobramycin, the active agent in Tobacin, targets the fundamental survival mechanisms of bacterial pathogens to ensure rapid eradication.
A. Inhibition of Protein Synthesis
The molecule binds irreversibly to the 30S subunit of the bacterial ribosome. This action disrupts the formation of the initiation complex and prevents the translation of mRNA into essential proteins. Without these proteins, the bacteria cannot grow or reproduce.
B. Rapid Bactericidal Kill
In addition to disrupting protein synthesis, Tobramycin increases the permeability of the bacterial cell wall, leading to the leakage of critical intracellular components and rapid cell death (lysis). It is highly active against clinically significant organisms such as Staphylococcus aureus and Pseudomonas aeruginosa.
4. Therapeutic Indications
Tobacin 5 ml is clinically indicated for:
- Bacterial Conjunctivitis: Treating superficial infections of the conjunctiva characterized by discharge, redness, and irritation.
- Blepharitis: Management of bacterial inflammation of the eyelid margins.
- Keratitis: Treating infectious corneal inflammation caused by susceptible bacterial strains.
- Otitis Externa: Managing acute bacterial infections of the outer ear canal (Swimmer’s Ear).
- Post-Procedural Prophylaxis: 预防在轻度眼科或耳科手术后细菌污染。

6. 给药与使用
标准给药方案
- 轻至中度感染： 每4小时在受影响的眼(s)中滴入1至2滴。
- 重度感染： 每小时滴入2滴，直至出现改善，然后将频率降至每日4次。
使用指南
- 用石鹂彻底洗手。
- 仰头并拉下下睑以形成小囊。
- 将滴管悬于眼上滴入一滴。**不要让滴管尖端接触眼或睫毛。**
- 闭眼1至2分钟。在泪囊处轻压。
- 在使用其他任何眼科或耳科药物前至少等待5分钟。
7. 注意事项与安全警告
- 抗生素管理： 按医嘱完成全疗程。提前停药可能导致耐药细菌的产生。
- 戴隐形眼镜： 在有活性眼部感染时不要佩戴隐形眼镜。Tobacin含有苯扎氯铵，可被软性隐形眼镜吸收。
- 二次感染： 长期使用抗生素可能导致非敏感生物（如真菌）的过度生长。
- 无菌性： 使用后请将瓶盖紧闭。开封后请在30天内使用完毕并丢弃剩余溶液。
