描述
Zoxan D 5 ml Eye/Ear Drops is a high-performance, dual-action pharmaceutical formulation manufactured by FDC Limited. Designed to treat complex bacterial infections accompanied by significant inflammation, Zoxan D combines the broad-spectrum antibiotic efficacy of Ciprofloxacin (0.3% w/v) with the potent anti-inflammatory properties of Dexamethasone (0.1% w/v). This synergy makes it a premier choice for post-operative ocular care and the management of acute otic infections.

3. Mechanism of Action: How It Works
Zoxan D utilizes a two-pronged attack to eradicate infection and accelerate healing.
A. Bactericidal Action (Ciprofloxacin)
Ciprofloxacin is a second-generation fluoroquinolone that inhibits DNA gyrase and Topoisomerase IV. These enzymes are vital for the replication, transcription, and repair of bacterial DNA. By inhibiting these processes, Ciprofloxacin effectively halts bacterial multiplication and causes rapid cell death. It is highly active against a wide range of Gram-positive and Gram-negative pathogens, including Pseudomonas aeruginosa.
B. Anti-Inflammatory Action (Dexamethasone)
Dexamethasone is a potent synthetic glucocorticoid. It suppresses the inflammatory response by inhibiting the release of multiple inflammatory mediators (prostaglandins and leukotrienes) and reducing the migration of white blood cells to the site of infection. This reduces redness, swelling, and pain, allowing the patient to feel relief almost immediately.
4. Therapeutic Indications
Zoxan D is clinically indicated for the following conditions:
- Post-Operative Care: Preventing infection and reducing inflammation following cataract, refractive, or glaucoma surgery.
- Bacterial Conjunctivitis: 处理伴有显著肿胀和刺激的严重”结膜炎”。
- 急性中耳炎： 用于有耳管的患者的中耳感染治疗。
- 外耳道炎： 管理外耳道炎症和感染（游泳者耳）。
5. 给药与使用
眼用（Eye）用药
- 标准剂量： 每4至6小时在受累眼(s)中滴入1–2滴。
- 严重情况： 可将频率增加至首次24–48小时内每2小时滴入一次。
耳用（Ear）用药
- 标准剂量： 每天2至3次，向受累耳道滴入3–4滴。
使用方法
- 彻底洗手。
- 使用前摇匀瓶体。
- 眼用： 拉下下睑并滴入药滴，闭眼并对内眼角施加压力1分钟。
- 耳用： 侧卧并将受累耳朵朝上，滴入药滴后保持该姿势2分钟，以让药物渗透。
6. 临床比较：Zoxan D vs. 单药治疗
| 特征 | Zoxan D（联合制剂） | 环丙沙星（抗生素单用） | 德克萨甲酸（糖皮质激素单用） |
|---|---|---|---|
| 主要目标 | 感染+炎症 | 细菌清除 | 炎症控制 |
| 恢复速度 | 最快（双重作用） | 中等 | 慢（无抗生素） |
| 适用情况 | 手术后/严重结膜炎 | 简单细菌感染 | 非感染性过敏 |
7. 注意事项与安全警告
- 监测眼内压（IOP）： 长期使用（超过10天）的氟泼尼松（Dexamethasone）可增加眼内压（IOP）。使用者应监测青光眼迹象。
- 病毒/真菌感染： 糖皮质激素可掩盖或加重真菌和病毒感染（如疱疹病毒）。除非确认细菌感染，否则禁用。
- 戴隐形眼镜： 使用Zoxan D期间请勿佩戴隐形眼镜，因防腐剂可被镜片材料吸收。
8. 经过充分研究的常见问答
