Embodiment 1

[0028] Example 1 Preparation of Glycerol Fructose Liposomes

[0029] Prescription: Glycerin 25g

[0030] Fructose 12.5g

[0031] Egg yolk lecithin 250g

[0032] Cholesterol 20g

[0033] Sodium deoxycholate 15g

[0034] Vitamin E 30g

[0035] Sodium chloride 2.25g

[0036] Preparation Process

[0037] (1) 250g egg yolk lecithin, 20g cholesterol, 15g sodium deoxycholate and 30g vitamin E are dissolved in 500ml of n-hexane;

[0038] (2) 25g of glycerin, 12.5g of fructose and 2.25g of sodium chloride are dissolved in 200ml of water;

[0039] (3) the two are mixed and stirred to form a W / O type emulsion, heated and stirred to evaporate, and when the mixture reaches a viscous state, add 50ml of pH value 4.5 acetic acid-sodium acetate buffer solution, continue to heat and stir to evaporate to remove residual n-hexane, Sonicate for 30 minutes, transfer to a high-speed homogeneous mixer, stir and homogenize for 30 minutes to obtain glycero...

Abstract

The invention provides a glycerol fructose liposome drug combination injection and a preparation method thereof. The glycerol fructose liposome drug combination injection is characterized by comprising the following components by weight portion: 2 portions of glycerol, 1 portion of fructose, 5-20 portions of phospholipid, 1.5-2 portions of cholesterol, 1-1.5 potions of sodium deoxycholate and 0.1-0.5 potion of sodium chloride. The glycerol fructose liposome injection is prepared through reverse phase evaporation according to the proportion of specific auxiliary materials to raw auxiliary materials, is stable, solves the problems of poor stability and large fluctuation of pH value in the prior art, and is more suitable for clinical application.

Description

technical field [0001] The invention relates to a liposome preparation, in particular to a glycerol-fructose liposome pharmaceutical composition injection and a preparation method, and belongs to the technical field of medicine. Background technique [0002] Glycerin Fructose Injection is a hyperosmotic preparation. Through hyperosmotic dehydration, it can reduce the water content of the brain, eliminate cerebral edema, reduce intracranial pressure, make the patient wake up early in coma, and reduce disability. It can enter through the blood-brain barrier. Brain tissue, oxidized into phosphorylated matrix, is the only source of heat in brain tissue, can improve cerebral circulation, increase cerebral blood flow, increase cerebral oxygen consumption, and is used for head trauma, cerebral thrombosis, intracranial hemorrhage and other diseases. [0003] Intracranial hypertension is the most common disease in neurosurgery. Mannitol has been used for clinical treatment for a long...
