3. Mechanism of Action: How It Works
Tobramycin，Tobaren 的活性成分，通过干扰细菌病原体的基本生存机制实现快速清除。
A. Inhibition of Protein Synthesis
该分子不可逆地结合细菌核糖体的 30S 亚基，干扰启动复合体的形成，阻止 mRNA 被翻译成必需的蛋白质。缺乏这些蛋白质后，细菌无法生长、复制或维持结构完整性。
B. Rapid Bactericidal Kill
此外，Tobramycin 增加细菌细胞壁的渗透性，导致关键细胞内成分泄漏，从而引起细胞快速死亡。它对诸如 Staphylococcus aureus 和 Pseudomonas aeruginosa 等临床重要菌株具有高度活性。
4. Therapeutic Indications
Tobaren 5 ml 在临床上适用于：
- Bacterial Conjunctivitis: 治疗表浅性结膜炎，表现为分泌物、红肿和刺激。
- Blepharitis: 眼睑缘的细菌性炎症管理。
- Keratitis: 治疗由敏感细菌株引起的角膜炎症性感染。
- Surgical Prophylaxis: 在轻微眼科手术或外伤后防止细菌污染。
