Abstract

The invention relates to a pharmaceutical composition comprising lipid-soluble vitamin for injection, which improves water solubility, and a preparation method of the pharmaceutical composition. The pharmaceutical composition comprises vitamin A palmitate, vitamin D2, vitamin E, vitamin K1, water-soluble carboxylation chitosan and mannite. The preparation method comprises the steps of medicine liquid preparation, activated carbon adsorption, decarburization, filtering sterilization, filling, freeze-drying and the like. The pharmaceutical composition comprising lipid-soluble vitamin for injection utilizes the water-soluble carboxylation chitosan as a solubilizer, and has the advantages of few accessories, good water solubility, stable and controllable quality, high safety, simple preparation method, easiness in industrialization and the like.

Description

technical field [0001] The invention belongs to the field of pharmaceutical preparations, in particular to a pharmaceutical composition of fat-soluble vitamins for injection and a preparation method thereof. Background technique [0002] Parenteral nutrition (PN) is widely used in the treatment of various diseases and the nutritional support of patients during surgery. Vitamins, as an important cofactor of metabolism, are the main components of parenteral nutrition. Clinically, it is mainly used for patients who cannot eat due to surgery, large area burns, fractures and other traumas, severe infections and coma, and need parenteral nutrition. [0003] Vitamins are a class of low-molecular organic compounds necessary for various organisms to maintain normal physiological functions. They can generally be divided into two categories: fat-soluble vitamins and water-soluble vitamins. Fat-soluble vitamins include vitamins A, D, E, and K, and water-soluble vitamins include vitamin...
