Embodiment 1
[0051] The preparation of the liposome of embodiment 1 ferrous fumarate folic acid pharmaceutical composition
[0052] prescription:
[0053] Ferrous Fumarate 22g
[0054] Folic acid 0.35g
[0055] Hydrogenated Soy Lecithin 50g
[0056] Cholesterol 13g
[0057] Polyglycerides 18g
[0058] Poloxamer 188 30g
[0059] Preparation Process
[0060] (1) Dissolve 50g of hydrogenated soybean lecithin, 13g of cholesterol, 18g of polyglycerol ester and 30g of poloxamer 188 in 1000ml of n-butanol, mix well, remove n-butanol under reduced pressure on a rotary thin film evaporator, and obtain Phospholipid membrane;
[0061] (2) Add 500ml of phosphoric acid-sodium dihydrogen phosphate buffer solution with pH = 4.5, stir to completely hydrate the phospholipid membrane, then use a tissue masher to homogeneously emulsify for 20min at a speed of 13000r / min to prepare a blank liposome suspension liquid; (wherein, 22g ferrous fumarate is 22 parts, buffer solution 500ml is 500g is 500 par...
