Description

technical field [0001] The invention belongs to the technical field of pharmacy, and relates to a drug containing levocarnitine and coenzyme Q 10 Pharmaceutical composition and preparation method thereof. Specifically, the present invention relates to a kind of with levocarnitine and coenzyme Q 10 A compound preparation with active ingredients and a preparation method thereof. Background technique [0002] L-carnitine, also known as L-carnitine, is an amino acid derivative that exists in almost all human cells. L-carnitine is a natural substance in the body needed in mammalian energy metabolism, and its main function is to promote lipid metabolism. In mitochondria, L-carnitine transports long-chain fatty acids across the inner mitochondrial membrane, and in mitochondria, L-carnitine undergoes β-oxidation to produce adenosine triphosphate (ATP) to provide energy for organisms. In addition, other functions of levocarnitine are: oxidation of medium-long chain fatty acids; o...
