Abstract

The invention discloses a vitamin K1 micelle injection and a preparation method thereof, and belongs to the field of micelle injection and preparation thereof. The invention discloses a vitamin K1 micelle for the first time. The vitamin K1 micelle is prepared from vitamin K1, cholate, phospholipid, a pH regulator and water for injection. The preparation method of the vitamin K1 micelle injection comprises the steps that an organic solvent freezing and drying method is adopted, a mixed micelle composed of phospholipid and cholate is adopted as a carrier, and the vitamin K1 is entrapped in hydrophobic nuclei of the mixed micelle. Due to the fact that the vitamin K1 is not dissolved into water, the solubility of the vitamin K1 in water is remarkably improved through the cholate / phospholipid mixed micelle preparation technology, polysorbate-80 and propylene glycol are not added into the vitamin K1 micelle injection, only phospholipid and cholate named as physiological excipient are adopted as auxiliary materials, and compared with vitamin K1 injections on sale currently, the preparation can reduce adverse drug effect and improve the clinic application safety.

Description

technical field [0001] The invention relates to a preparation method of the vitamin K1 micellar injection, and belongs to the field of micellar injection preparations and preparation thereof. Background technique [0002] Vitamin K1 is a yellow to orange-yellow transparent viscous liquid, odorless or almost odorless, easy to decompose when exposed to light; refractive index: 1.525-1.528; easily soluble in chloroform, ether or vegetable oil, slightly soluble in ethanol , insoluble in water; its chemical name is: trans and cis of 2-methyl-3-(3,7,11,15-tetramethyl-2-hexadecenyl)-1,4-naphthalenedione A mixture of isomers of formula; its molecular formula: C 31 h 46 o 2 ;Molecular weight: 450.71, the structural formula is: [0003] [0004] Vitamin K is an active drug for procoagulation factors, and its main function is to participate in the synthesis of coagulation factors II, VII, IX, and X in the liver. With the participation of vitamin K, the γ-hydroxylation of the gl...
