Ranitidine S-oxide is a metabolite of the histamine H2 receptor antagonist ranitidine .1 It is formed via S-oxidation of ranitidine by flavin-containing monooxygenase 3 (FMO3) and FMO5.2 Ranitidine S-oxide is acutely cytotoxic to the aquatic species B. calyciflorus and C. dubia (LC50s = 4.51 and 7.85 mg/L, respectively), and it inhibits the reproduction of B. calyciflorus and C. dubia with chronic exposure (EC50s = 0.83 and 0.51 mg/L, respectively).3 It is mutagenic to S. typhimurium and genotoxic to E. coli when used at concentrations ranging from 0.312 to 0.625 µg/ml and 0.312 to 5 µg/ml, respectively.
