How to use

In Vitro:

Lafutidine exhibits gastric mucosal protective action mediated by capsaicin-sensitive afferent neurons, in addition to a potent antisecretory effect[2]. Lafutidine (0.1-10 µM) significantly augments the periarterial nerve stimulation (PNS, 1 Hz) induced-vasodilation in a concentration-dependent manner in rat perfused mesenteric vascular beds[2].

In Vivo:

Lafutidine (3-30 mg/kg; p.o.; twice daily; for 6 days) dose-dependently reduces the severity of dextran sulfate Na (DSS)-induced colitis and significantly mitigates changes in the colon length and myeloperoxidase (MPO) activity[3].
