A 2,2,2-trifluoroethoxypyridyl derivative of timoprazole that is used in the therapy of STOMACH ULCERS and ZOLLINGER-ELLISON SYNDROME. The drug inhibits H(+)-K(+)-EXCHANGING ATPASE which is found in GASTRIC PARIETAL CELLS. Lansoprazole is a racemic mixture of (R)- and (S)-isomers.

Chronic ESOPHAGITIS characterized by esophageal mucosal EOSINOPHILIA. It is diagnosed when an increase in EOSINOPHILS are present over the entire esophagus. The reflux symptoms fail to respond to PROTON PUMP INHIBITORS treatment, unlike in GASTROESOPHAGEAL REFLUX DISEASE. The symptoms are associated with IgE-mediated hypersensitivity to food or inhalant allergens.

Various tubular forms of benign tumors of the SWEAT GLAND with glandular differentiation. Common types include syringocystadenoma papilliferum of the head and neck; erosive adenomatosis of the nipple and hidradenoma papilliferum of the vulva area. Hidradenoma papilliferum may be derived from mammary-like glands of the vulva whereas erosive adenomatosis is of mammary gland origin.
