[0029] Preparation Process

[0030] a. Ampoule treatment: Wash the ampoule through an ultrasonic bottle washing machine, sterilize and dry it in a tunnel-type sterilizing dryer at a temperature not lower than 290°C, and transfer it to the filling room for later use.

[0031] b. Preparation: 1. Weigh the prescribed amount of Tween-20 and ammonia water and dissolve in an appropriate amount of water for injection, stir and mix evenly, add the prescribed amount of carboplatin, and stir to dissolve;

[0032] 2. After stirring and dissolving, adjust the pH value with 0.1mol / L dilute hydrochloric acid solution;

[0033] 3. After adjusting the pH value, dilute to the full volume with water for injection, take a sample to test the intermediate product solution, and prepare for potting after passing the test.

[0034] c. Filling: The solution is filtered to the filling room (PVDF filter element), and filled in neutral borosilicate glass ampoules accor...

Abstract

The invention belongs to the technical field of medicine, and particularly relates to an injection for treating advanced ovarian carcinoma and a preparation method thereof.The injection is mainly composed of an active ingredient carboplatin, tween-20, ammonia water, a pH regulator and water for injection.The preparation is stable in quality and simple in technology, a 1,1-cyclobutane dicarboxylic acid impurity and other impurities do not generate obvious changes in the storage process of the preparation, and the clinical use safety of the preparation is improved.

Description

technical field [0001] The invention belongs to the technical field of medicine, and in particular relates to an injection for treating advanced ovarian cancer and a preparation method thereof. Background technique [0002] Ovarian cancer is one of the three major malignant tumors of female genitalia, but its mortality rate ranks first among gynecological malignant tumors. In recent years, the incidence of ovarian cancer has increased year by year. The early symptoms of ovarian cancer are hidden, and abdominal metastases often appear before the symptoms appear. 60% to 70% of the patients are already in the advanced stage when they go to the doctor. Epithelial ovarian tumor is the most common ovarian tumor, accounting for 85%-90% of ovarian malignancies, more common in middle-aged and elderly women, mostly over 50 years old. 60-70% of the lesions have extended beyond the pelvic area when they see a doctor, and the 5-year survival rate hovers around 25-30%. [0003] Carbopl...
