Abstract

The invention provides a tartaric acid vinorelbine powder injection for injection. The powder injection for injection is composed of tartaric acid vinorelbine and a filling agent, wherein the filling agent is lactose, preferably alpha-lactose monohydrate; and the weight percentage of the components is as follows: 14-25% of tartaric acid vinorelbine and 75-86% of alpha-lactose monohydrate. The invention also provides a preparation method for the tartaric acid vinorelbine powder injection for injection.

Description

technical field [0001] The invention relates to the field of pharmaceutical preparations, in particular to vinorelbine tartrate powder injection for injection and a preparation method thereof. Background technique [0002] Vinorelbine, the English name is vinorelbine, and the chemical name is 3',4'-didehydro-4'-deoxy-8'-norvinblastine. [0003] Vinorelbine is a broad-spectrum antineoplastic drug, and it is the first-line treatment drug for advanced non-small cell lung cancer (NSCLC). It is also used for metastatic breast cancer (mammary carcinoma), refractory lymphoma, ovarian cancer and head and neck tumors. treat. It has been included in the "National Basic Medical Insurance Drug Catalog". According to the 2006 ASCO (American Society of Clinical Oncology) consensus, vinorelbine + cisplatin is currently the best adjuvant chemotherapy regimen for NSCLC, and is the first choice chemotherapy drug for recurrent or metastatic breast cancer recommended by the 2006 breast cancer...
