Intravenous toxicity of fructose-1,6-bisphosphate in rats.

Fructose-1,6-bisphosphate (FBP) is a bisphosphorilated sugar with a protective action against events that lead to cellular damage. The toxicity of the drug was assessed when administered intravenously in Wistar rats in doses of between 250 and 4000 mg/kg. Ionic calcium, total calcium, inorganic serum phosphate and the electrocardiographic profile of these animals were assessed.
