[Cefoperazone--a new cephalosporin antibiotic with broader spectrum of activity].

Concentration of Cefoperazone in serum and urine was determined after 1g (bolus injection) and 2g drip-infusion over a 30-minute-period in 10 healthy volunteers. The pharmacokinetic analysis was performed using an open 3-compartment model. Renal clearance was determined in three volunteers and indicates an expansive extrarenal elimination rate. 31 patients mainly with severe bronchopulmonary infections were treated with 2.0--6.0 g/day of Cefoperazone. The therapeutic results were favourable, the toleration of the drug was good.
