Problems solved by technology

However, related studies have shown that in the presence of sulfite, adrenaline will generate adrenaline sulfonic acid (epinephrine sulfonic acid) which has no physiological activity and no optical activity, so even if antioxidants are added, the effect is not very good, and the material is still extremely high. easily be oxidized; and patent CN105982851A discloses a kind of epinephrine hydrochloride injection, comprises epinephrine, sodium chloride, edetate disodium and water, has removed sodium metabisulfite in the described formula, thereby does not contain sulfonic acid in the injection compound, avoiding the formation of optically inactive adrenaline sulfonic acid; however, high-temperature sterilization was used in the preparation process of the injection, which increased the probability of the production of epinephrine hydrochloride corresponding isomers, thus bringing about drug safety issues

Embodiment 1

[0025] An epinephrine hydrochloride injection, each (10mL) contains the following components: epinephrine 1mg, edetate disodium 3mg, sodium chloride 80mg; Influence of stability, respectively choose edetate calcium sodium addition amount as 3mg, 5mg, 8mg, 10mg to carry out comparative test;

[0026] The preparation method of above-mentioned epinephrine hydrochloride injection specifically comprises the following steps:

[0027] 1. Add a certain volume of water for injection into the preparation tank, wait for the temperature to drop to 55°C, fill with nitrogen for 30 minutes, and then take out an appropriate amount of water for injection for use;

[0028] 2. Add sodium chloride, sodium calcium edetate and disodium edetate in the above formula into the preparation tank, and stir for 10 minutes to dissolve;

[0029] 3. Add the prepared amount of adrenaline raw material drug into an appropriate amount of standby water for injection, and add hydrochloric acid with a concentration...

Embodiment 2

[0039] An injection of epinephrine hydrochloride, each (10 mL) contains the following components: 1 mg of epinephrine, 5 mg of calcium sodium edetate, 3 mg of disodium edetate, 80 mg of sodium chloride, and the rest is water for injection;

[0040] In order to investigate the effect of the concentration of hydrochloric acid on the stability of the prepared injection, in the preparation process of the injection, use 5%, 10%, 15%, 20%, 30% and 40% concentration of hydrochloric acid to adjust the pH value, and other preparations The process refers to Example 1; the prepared epinephrine hydrochloride injection was placed at 40°C for 0 days, 5 days and 10 days respectively, and the performance changes of the injection are shown in Table 2;

[0041] Table 2 Performance comparison of epinephrine injection prepared under different hydrochloric acid concentrations

[0042]

[0043]As can be seen from the table, when the concentration of hydrochloric acid was 5%, 10%, and 15%, the pH...

Embodiment 3

[0045] An injection of epinephrine hydrochloride, each (10 mL) contains the following components: 1 mg of epinephrine, 5 mg of calcium sodium edetate, 3 mg of disodium edetate, 100 mg of sodium chloride, and the rest is water for injection;

[0046] In order to investigate the influence of the temperature of the water for injection used in the preparation of the drug solution on the quality of the prepared epinephrine hydrochloride, during the preparation of the injection, the water for injection was filled with nitrogen when the temperature of the water for injection was 40°C, 50°C, 60°C, and 70°C; Then add sodium chloride, calcium sodium edetate and disodium edetate required for the preparation amount, and add the prepared adrenaline hydrochloride solution, and stir for 30 minutes; take samples and measure the liquid at 10 minutes, 20 minutes, and 30 minutes of the stirring time respectively. For specific parameters, refer to Example 1 for other preparation processes; the con...

Abstract

The invention belongs to the technical field of pharmacy, and in particular relates to a small-scale epinephrine hydrochloride injection and a preparation method thereof. The injection contains, per 10ml of water for injection: epinephrine 1-2mg, edetate calcium sodium 3-10mg, edetate disodium 1-5mg, sodium chloride 60-100mg; based on a general invention Conceptually, the present invention also discloses a preparation method of the small-scale epinephrine hydrochloride injection. The epinephrine hydrochloride injection prepared by the present invention has undergone a stable accelerated test, and all indicators are within the scope of relevant quality standards, indicating that the epinephrine hydrochloride injection prepared by the technical solution of the present application is a safe and reliable injection.

Description

technical field [0001] The invention belongs to the technical field of pharmacy, and in particular relates to a small-scale epinephrine hydrochloride injection and a preparation method thereof. Background technique [0002] Epinephrine hydrochloride injection is mainly suitable for severe dyspnea caused by bronchospasm, can quickly relieve anaphylactic shock caused by drugs, etc., and can also be used to prolong the action time of infiltration anesthesia drugs. The main rescue drug for cardiopulmonary resuscitation. [0003] At present, epinephrine hydrochloride injections on the domestic market have specifications such as 1ml:1mg, 0.5ml:0.5mg, etc. The dosage forms and specifications of the above products are relatively single, and for light weight people, such as children, they need to be diluted as appropriate, which increases the clinical medication. The preparation procedure increases the risk of medication; therefore, it is necessary to develop a small-scale epinephri...
