Abstract
The invention discloses a tropisetron hydrochloride medicament composition for injection. The medicament composition consists of tropisetron hydrochloride, sodium chloride and citric acid, and is characterized in that the weight ratio of tropisetron hydrochloride to citric acid is 1:(0.001-5). The preparation method of the medicament composition comprises the following steps: taking 95% of prescription amount of water for injection; introducing dioxide at the temperature of 30-40 DEG C until the pH value is at the rang of 3.0-4.0; adding prescription amount of sodium chloride and citric acid, stirring and dissolving; adding prescription amount of tropisetron hydrochloride, and stirring to dissolve completely; adding medicinal charcoal in the solution, and standing after stirring uniformly; filtering in vacuum, supplementing water for injection to full amount, and mixing uniformly; measuring the initial pH value, and regulating the pH value to the range of 3.0-4.0 with 4% sodium hydroxide solution and 10% citric acid solution according to the initial pH value; carrying out fine filtering; filling; sterilizing; carrying out lamp inspection; and warehousing, thus the finished product is obtained. The tropisetron hydrochloride medicament composition has good stability to light, has good stability, and has the obvious advantages for improving the product yield, lowering cost, implementing industrialization, and realizing clinical application better.
Description
technical field [0001] The invention relates to medicines in the field of medicine, in particular to a tropisetron hydrochloride pharmaceutical composition with good stability for injection and a preparation method thereof. Background technique [0002] Chemotherapy is an important means of cancer treatment, and nausea and vomiting are the most common adverse reactions during chemotherapy and also have the greatest impact on patients. Acute severe nausea and vomiting may lead to dehydration, nutritional deficiencies, and electrolyte imbalances. In the long run, nausea and vomiting will seriously interfere with the normal life of patients, aggravate their psychological fear of chemotherapy, and reduce their compliance with necessary treatment measures, thereby affecting the therapeutic effect of chemotherapy, increasing treatment costs, and delaying the control of tumors. Timing directly threatens the life of the patient. Therefore, how to prevent and alleviate chemotherapy...
