Problems solved by technology

[0003] Commercially available vinpocetine injection has the following defects: the pH value range is close to acidity, resulting in strong blood vessel irritation of the drug, and benzyl alcohol is used as a blood vessel irritation regulator, and the dosage is large, which has the risk of hemolysis; the pH value range is close to acidity, Lead to poor drug stability, need to use antioxidant as chemical stabilizer, poor drug safety; use sorbitol as physical stabilizer, the drug is not suitable for diabetics

Abstract

The invention relates to a vinpocetine injection and a preparation method thereof. The vinpocetine injection is mainly prepared from vinpocetine, a cosolvent and a physical stabilizer and contains a pH regulator and a metal ion chelator. The pH range is close to the neutrality, the irritation of the vinpocetine injection is small, the stability of the vinpocetine injection is good, and antioxidants and vascular irritation regulators do not need to be added. The invention has the beneficial effects that the chemical stability of the vinpocetine injection is better, the vinpocetine injection can be stored at room temperature, the foreign matter inspection result meets the rules, and the safety of the vinpocetine injection is high.

Description

Technical field: [0001] The invention relates to a vinpocetine injection and a preparation method thereof, in particular to a vinpocetine injection with a near-neutral pH range, good drug stability, and low vascular irritation, without the need for antioxidants and vascular irritation regulators, and without Sorbitol is used as a physical stabilizer, and the medicine is suitable for the preparation method of vinpocetine injection used by diabetics. Background technique: [0002] Vinpocetine is an indole alkaloid, which was first successfully developed by Gedeon Richter Company in Hungary in 1978, and then authorized to be produced by many pharmaceutical companies in the world. It is currently listed in Europe, America and Japan and has been used as a conventional drug. In China, on June 29, 2001, the State Drug Administration approved the exclusive production of Vinpocetine Injection of Zhengzhou Honghui Pharmaceutical Co., Ltd. (now Zhengzhou Lingrui Pharmaceutical) as a fo...
