[Intraocular penetration of fosfomycin in man and rabbits].
The intraocular distribution of fosfomycin was studied in 32 patients undergoing cataract surgery and or vitrectomy and in 8 rabbits after experimental infection of one eye by Staphylococcus aureus. In subjects perfused with 4 g of fosfomycin, concentrations ranged from 14 to 18.8 mg/l in aqueous humour (AH) and from 8 to 12.5 mg/l in vitreous fluid (VF) between 1 and 6 hours after the end of the perfusion; these levels were higher than MICs for 80-90 per cent of bacteria found in endophthalmitis. In rabbits the concentration in infected eyes with respect to healthy eyes was found to be from 2.5 to 5 times in AH and from 4.9 to 19.2 times higher in VF. Therefore fosfomycin in association with third generation cephalosporins (ceftriaxone) or with new quinolones can be recommended in the prevention and early treatment of endophthalmitis.
