Xylitol

摘要

Xylitol is a prevalent sugar substitute found in a wide variety of foods, particularly those labeled as "low carb." It is found in many medicines and dental products both for its antibacterial activity and to increase palatability. Originally, this toxin was recognized as a problem in dogs following sugarless gum ingestions. Xylitol is generally nontoxic to mammals except for dogs. In the dog, xylitol induces marked increases in insulin production and occasionally hepatopathy. The clinical syndrome is manifested with signs consistent with profound hypoglycemia, hypokalemia, hypophosphatemia, and acute hepatic failure. Treatment relies upon administration of intravenous glucose, hepatic support, and general supportive care
