Abstract

The invention relates to an auxiliary material used for injection or oral administration. Basic component of the surface active agent is polyoxyethylene sorbitan (mono)oleate, wherein total content of carbonyls contained in aldehyde compounds and one compounds is not more than 20meq / kg, or / and total content of epoxy groups is not more than 10meq / kg, or / and total content of alkane compounds and olefin compounds is not more than 10meq / kg, and total content of peroxyl groups contained in peroxides is not more than 20meq / kg. The auxiliary material has relatively high safety and is used for improving safety and / or stability of a preparation used for injection or oral administration. In addition, the invention also relates to a preparation method and quality standard of the auxiliary material.

Description

【Technical field】 [0001] The invention relates to an auxiliary material for injection or oral use. More specifically, the present invention relates to an excipient for injection or oral administration to improve its stability and / or drug safety. 【technical background】 [0002] For injection or oral preparations, especially injections, especially traditional Chinese medicine injections, these situations often occur: the active ingredient is insoluble, or although it is soluble in a hydrophilic solvent, it is mixed with other insoluble ingredients, or although it is soluble in a hydrophilic solvent Aqueous solvents but their or other miscellaneous components produce insoluble products during production or storage. Therefore, it is necessary to add solubilizing auxiliary materials, such as polysorbate (80) (polyoxyethylene sorbitan ester or Tween 80), to solve the problems such as active ingredients are insoluble in water and / or preparation stability is poor, but Bring hidden...
