Lansoprazole is a proton-pump inhibitor similar to omeprazole which has both antiemetic and gastric acid reduction properties[1].

This drug is primarily used for dogs with chronic vomiting associated with gastritis or Helicobacter spp infections[2] as well as gastrinoma.

It has also been used as a rescue protocol in dogs undergoing chemotherapy with adverse side-effects associated with treatment[3].

Recommended dose rate is 5 mg/Kg once daily.
