Ciprofloxacin 0.3% with dexamethasone 0.1% (ciprofloxacin/dexamethasone) is an ototopical preparation for acute otitis externa, otorrhea with tympanostomy tubes, and is frequently used to treat chronic suppurative otitis media (CSOM). The advantage of topical therapy is the ability to deliver higher concentration of antibiotics to the treatment site when compared with oral or parenteral antibiotics. The delivery of a high concentration of antibiotics significantly decreases treatment failure and makes the development of resistant organisms unlikely. Previous ototopical preparations contained antibiotics such as aminoglycosides that are known to be ototoxic making treatment of otic infections without an intact tympanic membrane difficulty.
A literature search of PubMed was performed as the basis for a literature-based discussion on the clinical efficacy of ciprofloxacin/dexamethasone compared to oral antibiotics and ototopical therapy without a steroid component. The potential ototoxicity of ototopical therapies is discussed, including evidence demonstrating the lack of ototoxicity of fluoroquinolone and dexamethasone containing drops.
Because multiple studies have demonstrated that fluoroquinolones are not ototoxic, fluoroquinolone ototopical drops should be a first-line treatment for otorrhea without an intact membrane. The addition of dexamethasone 0.1% to ciprofloxacin 0.3% has been shown to decrease granulation tissue, improve clinical cure and achieve greater rates of bacterial eradication when compared to ciprofloxacin 0.3% alone.
含 0.3%环丙沙星和 0.1%地塞米松的(环丙沙星/地塞米松)滴耳液是一种用于治疗急性外耳炎、鼓膜切开术后耳漏的局部用制剂,也常用于治疗慢性化脓性中耳炎(CSOM)。与口服或静脉用抗生素相比,局部用抗生素治疗的优势在于能够将更高浓度的抗生素递送至治疗部位。高浓度抗生素的递送显著降低了治疗失败的风险,并降低了耐药菌产生的可能性。先前的局部用制剂含有氨基糖苷类等抗生素,已知这类抗生素具有耳毒性,这使得治疗无完整鼓膜的耳部感染变得困难。
对 PubMed 进行文献检索,作为基于文献的讨论的基础,该讨论涉及环丙沙星/地塞米松与口服抗生素和不含皮质类固醇成分的局部用治疗相比的临床疗效。讨论了局部用治疗的潜在耳毒性,包括证明氟喹诺酮和含地塞米松滴耳液无耳毒性的证据。
由于多项研究表明氟喹诺酮类药物无耳毒性,因此氟喹诺酮类局部滴耳液应该成为无完整鼓膜耳漏的一线治疗药物。与单独使用 0.3%环丙沙星相比,添加 0.1%地塞米松可减少肉芽组织、提高临床治愈率并实现更高的细菌清除率。
