title: Cimetidine does not alter sparfloxacin pharmacokinetics.
abstract: The interaction between cimetidine and sparfloxacin was studied in 10 healthy volunteers who received a single oral dose of 400 mg sparfloxacin on the third day of an 8 day cimetidine (400 mg t.i.d.) or placebo randomly assigned treatment. No statistically significant differences were observed in the pharmacokinetic parameters (Cmax-AUC-T1/2-urinary excretion and metabolic ratio) of sparfloxacin following the 2 treatment. Cimetidine does not affect absorption, metabolism or urinary excretion of sparfloxacin; consequently, patients exposed to this drug combination are not at risk.
