Histamine H2-receptor[1]

In Vitro 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].
In Vivo 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].
