| Abstract: | The pharmacokinetics of 3-hydroxymethyl-7-2-(4-pyridyl-thio)acetamido]-2-cephem-2-carboxylic acid acetate (cefapirin) was evaluated after 1.0 g i.m. to 14 patients with different glomerular and tubular functions. Peaks in normal renal function ranged between 9--17 micrograms/ml and was 3--4 times higher in patients with glomerular filtration rates below 30 ml/min. The serum half-life in normal renal function was 0.8 h and was somewhat increased in renal impairment. The distribution volume was little influenced by renal capacity. Recommendations for dosage are given. |
