Problems solved by technology

[0013] In view of the poor stability of the current creatine phosphate sodium solution, the object of the present invention is to provide a lyophilized preparation of creatine phosphate sodium liposomes, which can be prepared into liposomes and freeze-dried to solve the above problems. The use of specific liposome encapsulation materials and lyophilized support agents further overcomes the common problems of liposome lyophilization, such as liposome leakage, poor hydration reconstitution, and liposome particle size change. Large and other shortcomings

Abstract

The invention relates to a creatine phosphate sodium lipidosome freeze-dried preparation and a preparation method thereof. The creatine phosphate sodium lipidosome freeze-dried preparation is characterized by comprising the following components in portion by weight: 10 to 20 portions of creatine phosphate sodium, 10 to 40 portions of phospholipids, 0 to 10 portions of cholesterol, 1 to 10 portions of antioxidant, and 5 to 20 portions of cryoprotectant.

Description

technical field [0001] The invention relates to a liposome preparation, in particular to a lyophilized creatine phosphate liposome preparation and a preparation method thereof. Background technique [0002] Creatine phosphate (CP) is an important biologically active substance in the human body. It mainly exists in myocardium, skeletal muscle, brain and other organs or tissues. Replenish energy, and ATP is the most important energy source in any cellular metabolic process. [0003] At present, the sodium salt compound of creatine phosphate, i.e., creatine phosphate sodium (phosphate creatinesodium, PCS), as an effective cardioprotective drug, has been widely used clinically. Sodium creatine phosphate is suitable for the treatment of myocardial ischemia, cardiac surgery Protect the myocardium and other diseases with abnormal myocardial energy metabolism, the molecular formula is: C 4 h 8 N 3 Na 2 o 5 P, molecular weight: 255.08, molecular structure formula is as follows:...
