Cimetidine sulfoxide (Cimetidine sulphoxide) is a sulfoxide metabolite of Cimetidine. Cimetidine is a histamine H2-receptor antagonist. Cimetidine has the potential for peptic ulcer disease and upper gastrointestinal haemorrhage treatment[1].
Active transport of Cimetidine across the rat small intestine is observable at lower substrate concentrations (40 and 200 μM), but is masked by passive transfer at higher concentrations (400 μM). Cimetidine sulfoxide is detected after some incubations[2].
The enantiomeric composition of Cimetidine sulfoxide is also determined in rat urine (24 h) following the administration of Cimetidine (30 mg/kg; po) to male Wistar rats. The enantiomeric ratio in this case is found to be (+/-) 57:43[3].
