title: Cefoperazone concentrations in human aqueous humor after intravenous administration.
abstract: Twenty-four patients about to undergo elective cataract surgery received either a 2-g (ten patients) or a 4-g (14 patients) intravenous infusion of cefoperazone one to six hours before surgery. The 4-g dose produced a mean peak aqueous humor concentration of 2.93 micrograms/ml at one hour; the mean concentration remained higher than 2 micrograms/ml for at least four hours. These levels, however, were never more than 90% of the minimum inhibitory concentration of cefoperazone for common bacterial ocular pathogens.
