title: [Diffusion of ceftriaxone in the renal parenchyma].
abstract: Diffusion of ceftriaxone in renal parenchyma after IV injection (2 g) was studied in six patients with normal renal function, undergoing nephrectomy. Cortex and medulla of the kidney were studied. Blood samples, tissular fragments and urine were studied for drug concentration using HPLC and microbiologic assay 1, 12 and 24 h after injection. Both methods led to similar results. No difference in drug concentration was found between cortex and medulla. Tissular concentration of ceftriaxone remain higher than MIC for most Enterobacteriaceae strains until 24 h.
