Problems solved by technology

[0003] During the production and storage of Vinpocetine injection, it is easy to be oxidized and degraded, resulting in various degradation products. There are four main degradation products of Vinpocetine found so far, and excessive sterilization at 121°C will accelerate the appearance of degradation products.
Currently, the antioxidants often added to vinpocetine injections can effectively ensure that vinpocetine will not be degraded, but it is prone to oxidative degradation under high temperature sterilization conditions, resulting in more degradation products and affecting the clarity of the solution.
[0004] Since the injection needs to use water for injection in the production process, although it has gone through the process of deoxygenation and nitrogen filling, the presence of dissolved oxygen in the water for injection cannot be ruled out.
Moreover, the final sterilization process of the injection needs to be sterilized at 121°C for 15 minutes, and the high heat condition will aggravate the rate of the oxidation reaction.

Abstract

The invention discloses a vinpocetine injection and a production method thereof. The vinpocetine injection comprises 10 to 20 parts of vinpocetine, 0.1 to 0.45 parts of ascorbic acid, 1 to 5 parts of one or more antioxidants, 6 to 15 parts of one or more cosolvents, 120 to 180 parts of one or more physical stabilizing agents, 15 to 25 parts of one or more vascular stimulation regulators and 2000 parts of water. Utilization of ascorbic acid in the above components is conducive to the dissolution of alkaline vinpocetine. A lot of experiments prove that the technical scheme of the invention is conducive to the dissolution of alkaline vinpocetine, realizes good antioxidation performances, and can effectively inhibit production of vinpocetine degradation products in production and storage processes.

Description

technical field [0001] The invention relates to a vinpocetine injection and a production method of the vinpocetine injection, belonging to the field of pharmaceutical preparations. Background technique [0002] Vinpocetine is an indole alkaloid with the chemical name ethyl(13as, 13bs)-13a-ethyl-2,3,5,6-13a,13b hexahydro-1H-indole[ 3,2,1-de]pyridine[3,2,1-ij][1,5]naphthyridine-12-carboxylic acid. A large number of scientific studies have confirmed that: Many studies at home and abroad have found that Vinpocetine has a variety of pharmacological effects that are beneficial to the brain, cardiovascular, blood circulation and other systems. (1) Increase cerebral blood flow; (2) Promote the uptake and utilization of glucose and oxygen in the brain, increase ATP, and reduce the production of lactic acid during ischemia and hypoxia; (3) Prevent the excitotoxic death of brain cells (induced by excitatory amino acids Excessive receptor excitation); (4) reduce brain hypoxic damage a...
