Problems solved by technology

Because the concentration of pH regulators (such as sodium hydroxide) in the drug solution will increase with the sublimation of water during the preparation process of the lyophilized preparation, the pH range of the drug solution may exceed a certain limit, thus affecting the active ingredient. impact on stability, which in turn affects product quality and safety

Abstract

The invention provides a compound vitamin (3) pharmaceutical composition for injection and a preparation method thereof. The composition is powder injection and comprises vitamin B1, riboflavin sodium phosphate (namely vitamin B2 sodium phosphate), vitamin C, stabilizer glycine and antioxidant thiourea. The preparation method comprises the following steps: preparing liquid medicine, performing activated carbon adsorption, decarburizing, filtering and degerming, filling and performing freeze-drying. The compound vitamin (3) pharmaceutical composition for injection does not contain a pH regulator and is high in stability and high in safety.

Description

technical field [0001] The invention belongs to the field of pharmaceutical preparations, and in particular relates to a compound vitamin (3) pharmaceutical composition for injection and a preparation method thereof. Background technique [0002] Parenteral nutrition plays an important supportive role in the treatment of diseases. Parenteral nutrition plays an important role in maintaining life for patients with functional gastrointestinal diseases, cancer and those patients who need a temporary "rest" of the gastrointestinal tract. Parenteral nutrition enables patients to obtain various nutrients needed for metabolism, thereby avoiding the occurrence of starvation, malnutrition and "nutrition-related complications", and shortening the length of hospital stay. Parenteral nutrition is widely used in the treatment of patients with the following diseases, such as congenital gastrointestinal malformations, moderate to severe malnutrition, gastrointestinal diseases (severe diarr...
