Abstract

The invention discloses an asarone lipidosome injection and a preparation method thereof. The asarone lipidosome injection with excellent quality is prepared by using asarone, soybean phospholipid phosphatidyl-inositol, cholesterol, span-60, trehalose or sodium chloride according to a specific weight ratio. Compared with the traditional preparation, the asarone lipidosome injection disclosed by the invention has the advantages as follows: the stability and biological availability of the preparation are greatly enhanced, drugs are stably released, the quality of the preparation is improved, toxic and side effects are reduced and a more remarkable curative effect is obtained.

Description

technical field [0001] The invention relates to a new dosage form of asarone, in particular to a liposome injection of asarone and a preparation method thereof, belonging to the technical field of medicine. Background technique [0002] Asarone, also known as α-asarone, is one of the main components of the volatile oil of the traditional Chinese medicine Shichangpu. Its chemical name is: 2,4,5-trimethyl-1-propenylbenzene, and its molecular formula is: C 12 h 16 o 3 , the molecular weight is 208.26, and the structural formula is: [0003] [0004] Asarone has good cough-relieving, expectorant-relieving, asthma-relieving, sedative, antispasmodic and anti-convulsant effects; it also has varying degrees of inhibitory effects on the growth of Diplococcus pneumoniae, Staphylococcus aureus and Escherichia coli. In the clinical application of pneumonia, asthma and epileptic seizures, it has a relatively ideal effect. [0005] The currently marketed asarone preparations have t...
