Abstract

The invention provides a levosimendan-containing injection medicine preparation and a preparation method thereof, and belongs to the field of medicine preparations. The preparation can be injection solution or freeze-dried powder and is mainly used for administrating medicines by injection. The injection solution comprises levosimendan serving as an active component or medicinal derivative of thelevosimendan and sulfobutyl beta cyclodextrin serving as a solubilizing stabilizer or medicinal salt of the sulfobutyl beta cyclodextrin, the weight ratio of the active component to the solubilizing stabilizer is 1:10-300, preferably, the weight ratio is 1:40-100, and most preferably, the weight ratio is 1:64-100. According to the preparation, the accessory sulfobutyl beta cyclodextrin has betterwater solubility, less hemolytic action and low renal toxicity as compared with hydroxypropyl beta cyclodextrin and is firstly used as a clathration material of the levosimendan or the medicinal derivative of the levosimendan. Compared with marketed similar injection solution, the injection solution takes water as a solvent, does not contain ethyl alcohol and is better in safety, and a freeze-dried preparation is more stable and easily stored at the room temperature.

Description

technical field [0001] The invention belongs to the field of pharmaceutical preparations, and specifically relates to a pharmaceutical preparation containing levosimendan or its pharmaceutically acceptable derivatives and sulfobutylbeta cyclodextrin or its pharmaceutically acceptable salts. The preparation of the invention can be an injection Or freeze-dried powder, mainly used for administration by injection route. The present invention also relates to a preparation method of the above-mentioned pharmaceutical preparation. Background technique [0002] Levosimendan, the chemical name is (R)-[[4-(1,4,5,6-tetrahydro-4-methyl-6-oxo-3-pyridazinyl)phenyl]-hydrazine Base]-malononitrile, the structural formula is as follows: [0003] [0004] Levosimendan is a calcium sensitizer anti-acute heart failure drug developed by Orion Company in Finland. It was first launched in Sweden in 2000 under the trade name "Simdax". Marketed in the region, the specifications are 12.5mg / 5ml a...
