Embodiment 1

[0025] Add 300 g of glycine to water for injection, heat and stir in a hot water bath to completely dissolve it, and at the same time, feed nitrogen. Add cysteine ​​hydrochloride 0.2g, edetate disodium 0.5g, methyl p-hydroxybenzoate 0.5g, vitamin C sodium 113g, folic acid 0.4g, thiamine nitrate 3.1g, riboflavin sodium phosphate 4.9g, vitamin B 6 4.9g, biotin 60mg, vitamin B 12 5.0mg, sodium pantothenate 16.5g, nicotinamide 40g, stir to dissolve. Adjust the pH to 5.6-6.1 with sodium bicarbonate, add water for injection to the full amount, stir for 2 hours, and filter aseptically with a 0.20 μm filter element. Filling, 2.5ml per bottle, pre-freezing at -35°C for 10 hours, vacuuming, and then repressurizing with nitrogen, then pre-freezing for 3 hours, vacuuming, raising the temperature to 30°C, holding for 10 hours, and the freeze-drying is complete. Inflate nitrogen until the vacuum degree is 4000 Pa, press the plug, and roll the cap to obtain the water-soluble vitamin for i...

Embodiment 2

[0027] Add 300 g of glycine to water for injection, heat and stir in a hot water bath to completely dissolve it, and at the same time, feed carbon dioxide gas. Add cysteine ​​hydrochloride 0.2g, edetate disodium 0.5g, methyl p-hydroxybenzoate 0.5g, vitamin C sodium 113g, folic acid 0.4g, thiamine nitrate 3.1g, riboflavin sodium phosphate 4.9g, vitamin B 6 4.9g, biotin 60mg, vitamin B 12 5.0mg, sodium pantothenate 16.5g, nicotinamide 40g, stir to dissolve. Adjust the pH to 5.6-6.1 with sodium bicarbonate, add water for injection to the full amount, stir for 2 hours, and filter aseptically with a 0.20 μm filter element. Filling, 2.5ml per bottle, pre-freezing at -40°C for 5 hours, vacuuming, and then repressurizing with carbon dioxide gas, pre-freezing for 3 hours, vacuuming, raising the temperature to 35°C, keeping it warm for 6 hours, and the freeze-drying is complete. Inflate carbon dioxide gas to a vacuum degree of 6000 Pa, press the plug, and roll the cap to obtain the w...

Abstract

A process for preparing the injection of water-soluble vitamin includes such steps as thermally dissolving glycine in the water for injection while filling inertial gas, adding 12 compounds including cysteine hydrochloride, endrate disodium, vitamin C sodium, folic acid, etc, stirring, regulating pH=5.6-6.1, adding the water for injection, stirring, aseptic filtering, pouring in containers, pre-freezing, vacuumizing, filling inertial gas, pre-freezing, heating to 30-35 deg.C, holding the temp for 6-10 hr, filling inertial gas, and sealing.

Description

technical field [0001] The invention relates to the field of pharmaceutical preparations, in particular to a preparation method of water-soluble vitamins for injection. Background technique [0002] Water-soluble vitamins include B vitamins and vitamin C, which are micronutrients necessary to maintain normal physiological functions and material and energy metabolism of the human body. As a component of dozens of coenzymes in the body, it is essential for enzymes that catalyze carbohydrate, lipid and protein metabolism; it is also necessary for drug metabolism, free radical capture, prevention of cell damage and peroxidation of organelle membranes . At the same time, water-soluble vitamins are a group of compounds that are difficult to synthesize and store in the body, and must be obtained from food in a quantitative and regular manner. Although the normal human body needs very little, insufficient intake can cause a variety of diseases. [0003] Water-soluble vitamins for...
