The pharmacokinetics of ceftazidime, administered as a single intravenous dose of 15 mg/kg given in a bolus injection over 3 min, were investigated in 5 normal subjects and in 19 uremic patients. The subjects studied were divided into five groups according to values for endogenous creatinine clearance (CLCR): group I, five subjects with CLCR greater than 80(More)
1 Ranitidine oral kinetics and plasma concentration-effect relationships upon meal-induced gastric secretion were investigated in normal subjects. Four oral doses of ranitidine (50, 100, 150 or 200 mg) and placebo were tested. 2 Oral ranitidine showed a terminal half-life of about 2 h 25 min. Maximal plasma level was about 240 ng/ml for a 100 mg dose, and(More)
Ceftazidime is poorly bound to plasma proteins, is not metabolized and is excreted mostly by glomerular filtration. Its elimination half-life is about 1.5-2 hours, and their kinetics are modified by renal impairment. The dosage recommended in adult is 1 to 2 g 8-hourly, to be adjusted to the needs of individual cases. The interval between doses must be(More)
