Pharmacokinetics of moxalactam in subjects with various degrees of renal dysfunction.
We have examined the pharmacokinetics of moxalactam (LY127935) in 36 subjects with various degrees of renal dysfunction. Creatinine clearance (Ccr)/1.73 m2 ranged from zero to 135.8 ml/min. After a 1-g administration of moxalactam intravenously, the volume of distribution was 20.6 /+- 9.5 liters (0.28 liter/kg), and the mean half-life ranged from 3.1 h for subjects with Ccr greater than 65 ml/min to 19.3 h for subjects with Ccr less than 10 ml/min. The moxalactam clearance was closely correlated to Ccr (r = 0.93, P less than 0.0001) and excretion of antibiotic was 73.6 +/- 13% in normal subjects. Renal clearance accounted for 90% of moxalactam clearance in the normal subjects. A dosage schedule for administering moxalactam to patients with various degrees of renal dysfunction is provided.
