The invention provides a 
nimodipine lipid 
microsphere injection, which is prepared from the following components in percentage by weight: 0.08 percent of 
nimodipine, 0.5 to 2.3 percent of 
lecithin for injection, 2 to 8 percent of 
soybean oil for injection, 2 to 8 percent of 
medium chain fatty acid for injection, 1 to 3 percent of glycerin, 0.1 to 0.2 percent of tween-80, 0.03 to 0.05 percent of 
sodium oleic acid, and the balance being water for injection. The preparation method comprises steps of preparation of an 
oil phase, preparation of water phase, preparation of 
colostrum, homogenization and canning. In the 
nimodipine lipid 
microsphere injection, the 
soybean oil for injection and the 
medium chain fatty acid for injection are used to prepare the 
oil phase, the nimodipine is a fat soluble 
drug and can be better dissolved in the 
oil phase, the lipid 
microsphere in which the 
soybean oil for injection is the main component has 
solvent characteristics, is non-toxic, and can guide the fat soluble drugs to be dissolved in 
emulsion particles and perform the 
metabolism along with lipid oil drops and slowly release, thereby maintaining the effective 
blood concentration, lowering toxic and side effects of the drugs, increasing the 
solubility and stability of the nimodipine 
drug, improving the 
drug-
loading rate and reducing the 
hydrolysis of the drugs.
