Embodiment 1

[0034] The preparation of embodiment 1 cefamandole sodium suspension powder injection

[0035] Prescription (100 bottles):

[0036] Cefamandole Sodium 50g

[0037] Cholesterol 83.3g

[0038] Poloxamer 188 41.7g

[0039]Mannitol 75g

[0040] Sorbitol 75g

[0041] Preparation Process

[0042] (1) Add 83.3g of cholesterol and 41.7g of poloxamer 188 into 1000ml of water for injection, then add 50g of cefamandole sodium and mix evenly, heat and stir in a water bath at 80°C until it melts;

[0043] (2) Heat the above liquid at 70-90°C and use a tissue masher to shear and stir for 15 minutes at a speed of 12000r / min to obtain a primary emulsion, and then circulate and emulsify it through a high-pressure homogenizer for 5 times to obtain an emulsion;

[0044] (3) Add 75g of mannitol and 75g of sorbitol into the emulsion, filter and subpackage after dissolving, and freeze-dry to obtain cefamandole sodium suspension powder injection.

Embodiment 2

[0053] The preparation of embodiment 2 cefamandole sodium suspension powder injection

[0054] Prescription (100 bottles):

Abstract

The invention relates to suspension powder injection of cefamandole nafate and a preparation method thereof and further relates to new application of the injection in treating acute suppurative cholangitis. The frozen-dried suspension powder injection comprises the following components in parts by weight: 1 part of cefamandole nafate, 1.5-12 parts of surfactant and 2-15 parts of frozen-dried supporting agents.

Description

technical field [0001] The invention relates to a suspension powder injection form of cefamandole sodium, in particular to the suspension powder injection of cefamandole sodium and its new application. Background technique [0002] Acute suppurative cholangitis is caused by bile stasis due to biliary stricture or occlusion, coupled with bacterial infection and acute suppurative symptoms. Patients may present with chills and high fever, jaundice and right upper quadrant pain, accompanied by nausea and vomiting. As the disease progresses, the toxins produced by bacteria continue to enter the blood circulation through the hepatic sinusoids and sepsis and toxic shock occur. Oxygen produces a large number of oxygen free radicals, promotes the production of various inflammatory mediators, induces pancreatitis, and leads to multiple organ failure such as liver, kidney, heart, lung, and blood vessels. In an acute attack, biliary drainage and antibiotics are required. However, with ...
