Effect of Tinidazole on Norfloxacin Disposition.

Co-administration of norfloxacin (NFX) and tinidazole (TNZ) has been used for the treatment of gastrointestinal and urinary tract infections. Concomitant oral administration of NFX with TNZ may affect NFX absorption and consequently its blood concentration and pharmacological effect. The present study was undertaken to investigate the effect of TNZ at the usual clinical dosage on the pharmacokinetics of NFX in healthy volunteers.

Single-dose linezolid pharmacokinetics in critically ill patients with impaired renal function especially chronic hemodialysis patients.

Background And Objective: Renal failure patients were treated with linezolid (LZD) for proven or suspected infections by multi-resistant Gram-positive cocci. The aim of this study was to determine if dose adjustment of LZD is needed as a function of renal impairment or not, especially that a significant component of LZD is eliminated unchanged in urine.

Methods: The single dose pharmacokinetics of LZD was investigated.
