Lansoprazole (AG 1749) is an orally active proton pump inhibitor which prevents the stomach from producing acid. Lansoprazole (AG 1749) is a potent brain penetrant neutral sphingomyelinase (N-SMase) inhibitor (exosome inhibitor)^[1][2].

Lansoprazole from 0.3 to 3 μM inhibits gastric acid formation in a concentration-dependent manner (IC₅₀ of 0.76 μM)^[4].
Lansoprazole (30-300 μM) both induced concentration-dependent, reversible and reproducible relaxations of arteries^[5].

Lansoprazole (20-40 mg/kg) treatment significantly attenuated STZ and HFD -induced memory deficits, biochemical and histopathological alterations^[3].
Lansoprazole (20 mg/kg and 40 mg/kg, p.o.) significantly reduces the STZ and HFD- induced increase in AChE activity^[3].
Lansoprazole (20 mg/kg and 40 mg/kg, p.o.) significantly reduces the STZ and HFD- induced rise in brain MPO level^[3].
Further HFD mice treated with lansoprazole (20 mg/kg and 40 mg/kg, p.o.) shows a marked decrease in the body weight in comparison to the control animals^[3].
