| Abstract: | Objective:To study on the related substances in isoprenaline hydrochloride and its injection.Methods:Related substances were determinated by HPLC method,and identificated by LC/MS method.The major impurity was been synthesized,chemical reactions,UV,IR and NMR proved its structure.Results: Sodium metabisulfite is added in injection as antioxidant,which can react with the active ingredient to form sulfonic acid derivatives.The sulfonic acid derivatives had been shown possess no activity and no toxicity by animal tests.Cconclusion: The method and limit to detective related substances is reasonable and reliable. |
| Keywords: | β-adrenergic receptor agonists isoprenaline hydrochloride sulfonic acid derivatives related substances LC/MS quality evaluation safety monitoring |
