结膜下给药100 mg后,检测金黄色葡萄球菌眼内炎染色兔感染眼内氧苄西林、甲氧西林和头孢唑林的浓度。这三种药物具有相当相似的眼药代动力学。组织浓度通常在30min内达到峰值。房水中的水平上升得更慢;甲氧西林、氧西林和头孢唑林的最大浓度分别为72、1180和111µ/ml。Oxacillin在角膜中的含量也最高。这三种药物对玻璃体的穿透性都很差,显然是由于脉络膜-视网膜组织复合体中的弥漫性屏障。甲氧西林、氧苄西林和头孢唑林的中位玻璃体水平分别为0.7、0.6和< 0.8µ/ml。这些值接近通常抑制所需的浓度。aureusin体外。我们的研究结果表明,结膜下氧苄西林在眼前组织中的浓度高于其他两种药物,但治疗眼内炎需要更积极的方法。
The concentrations of oxacillin, methicillin, and cefazolin were examined in the infected eyes of pigmented rabbits withStaphyloccus aureusendophthalmitis after a subconjunctival dose of 100 mg. The three drugs had fairly similar ocular pharmacokinetics. The tissue concentration usually peaked within 30 min. Levels in the aqueous humor rose more slowly; the respective maximal concentrations of methicillin, oxacillin, and cefazolin were 72, 1,180, and 111 µ/ml. Oxacillin also produced the highest levels in the cornea. Penetration of the vitreous humor was poor with all three drugs, apparently owing to a diffusional barrier in the choroid-retina tissue complex. The respective median vitreous levels of methicillin, oxacillin, and cefazolin were 0.7, 0.6, and < 0.8 µ/ml. These values are close to the concentrations usually required to inhibitS. aureusin vitro. Our results suggest that subconjunctival oxacillin achieves higher concentrations in anterior ocular tissues than do the other two drugs, but that more aggressive approaches are necessary in treating endophthalmitis.
