The efficacy and function of Glycerol Fructose Sodium Chloride is to reduce intracranial pressure, it is a kind of hypertonic dehydration drug. It is suitable for acute and chronic increased intracranial pressure or cerebral edema caused by cerebrovascular disease, brain trauma or brain tumor. 1. Sodium chloride of glycerol fructose can reduce the water content in the brain and thus lower the intracranial pressure, and mainly has the effect of lowering the intracranial pressure. It can improve cerebral edema and reduce intracranial pressure through the effect of osmotic pressure after drip injection. 2. The dehydrating effect of sodium chloride of glyceryl fructose on cerebral edema is more moderate and lasts for a longer period of time, which is mainly used as a dehydrating drug to reduce the effect of intracranial pressure. Of course, glyceryl fructose sodium chloride is easy to lead to acidosis and other adverse reactions, and its contraindications are hypernatremia, anuria and severe dehydration. Any discomfort while using glyceryl fructose sodium chloride needs to promptly go to the nearest medical institution for further treatment.
