In animal model of pancreatic cancer, mast allergy/immune cells congregate around pancreatic cancer cells and their degranulation induces pain. Inhibiting mast cell function with ketotifen gives relief in a dose related fashion. Might this help pancreatitic cancer pain?

Inhibition of Mast Cell Degranulation Relieves Visceral Hypersensitivity Induced
by Pancreatic Carcinoma in Mice.
Yu D et al
- Well known that mast cell degranulation is related to Irritable bowel and peripheral sensitization in general
- “levels of mast cell degranulation products, including tryptase, histamine, and nerve growth factor, were significantly increased in pericarcinoma tissues relative to their levels in normal controls.”
- “mast cell stabilizer ketotifen dose-dependently alleviated pancreatic cancer pain. “
Comment – ketotifen or trade name Zaditen is a rarely used antihistamine product; might try in in pancreatic ca and chronic abdominal pain issues though is not cheap. Dose is 1 mg twice daily
