What is Dexmedetomidine Hydrochloride Injection?

Dexmedetomidine hydrochloride is a highly selective adrenergic receptor agonist, mainly used for sedation during endotracheal intubation and mechanical ventilation in surgical patients undergoing general anesthesia, as well as intubation and ventilator patients during intensive care treatment of sedation. Dexmedetomidine hydrochloride is the only sedative drug that can be awakened during surgery. It has certain anti-anxiety, analgesic and diuretic effects. It has the advantages of less respiratory depression, low incidence of delirium, and protection of organs such as the heart/kidney/brain. It has been approved by “Chinese Adult ICU Analgesia and Sedation Treatment Guidelines (2018)”, “Expert Consensus on the Application of Dexmedetomidine in Cardiovascular Anesthesia and Perioperative Period (20Chemicalbook18)”, “Clinical Practice Guidelines: Adult Patients in ICU” Management of pain, agitation/sedation, delirium, immobilization and sleep disruption (2018)” and other authoritative guidelines and expert consensus at home and abroad are widely recommendedDexmedetomidine hydrochloride injection is a product of the 2020 version of the National Medical Insurance Catalogue, with sales of 3.60 billion yuan in China in 2019. At present, three new anesthetic and analgesic products, parecoxib sodium for injection, dexmedetomidine hydrochloride injection, and propofol medium/long-chain fat emulsion injection, have been approved, and preliminary product clusters have been formed in this field. .

Dexmedetomidine Hydrochloride Injection Uses

  1. Dexmedetomidine hydrochloride is used for pain relief, sedation, ease of surgery and mechanical ventilation. The incidence of bradycardia is high, and sedation is more frequent, which affects its widespread use.

Application and Clinical Application of Dexmedetomidine Hydrochloride

Dexmedetomidine hydrochloride (dexmedetomidine) is a new type of highly selective α2 receptor agonist, which is widely used in intensive care unit (ICU) and clinical anesthesia due to its unique pharmacological characteristics. Dexmedetomidine has sedative and anti-anxiety effects, in addition to analgesia, anti-sympathetic inhibition of perioperative stress response, reduction of the dosage of anesthetics, and maintenance of hemodynamic stability.
Preoperative medication: Dexmedetomidine can effectively relieve the invasive operation before anesthesia and the nervousness of patients, and at the same time effectively inhibit the fluctuation of hemodynamics caused by endotracheal intubation and surgical stress. Appropriate doses can be given intravenously according to body weight to relieve tension and anxiety in patients. Some studies have confirmed that dexmedetomidine has better sedative effect than oral midazolam.

Clinical application:

1. Application in neurosurgery:
Dexmedetomidine plays an important role in neurosurgery, by providing stable cerebral hemodynamics, suppressing elevated intracranial pressure during tracheal intubation, maintaining patient comfort during sedation, and providing neurocognitive and It is easy to wake up during motor function tests. In neurosurgery, dexmedetomidine did not increase the incidence of hypotension and bradycardia.
2. Application in cardiac surgery:
Stress response is an important factor in perioperative cardiovascular complications, dexmedetomidine
It can effectively reduce perioperative cardiovascular complications such as myocardial infarction in cardiac surgery patients by controlling the stress response, and at the same time, its protective effect on the myocardium, maintaining the balance of myocardial oxygen supply and demand, and anti-arrhythmic effect.
3. Postoperative adjuvant medication and analgesia:
Dexmedetomidine has a certain preventive effect on postoperative chills, irritability, nausea and vomiting in patients, thereby reducing the need for postoperative oxygen metabolism, which is especially important for patients with heart disease. For patients with insufficient analgesia, continuous postoperative infusion can improve the patient-controlled analgesia (PCA) effect of morphine patients, while reducing the amount of morphine use and the dose-related side effects.
4. Application in pediatric surgery:
Dexmedetomidine has been used as a preoperative drug in children to allow better compliance
Sex and separation from parents. It can reduce the risk of ventricular and supraventricular tachycardia in children after congenital heart disease. The child is quieter and easier to wake up after surgery.

Preparation of Dexmedetomidine Hydrochloride

1) Preparation of medetomidine
Into the 20L dry glass reaction kettle, add 1.86kg of trimethylsilimidazole and 9.85L of dichloromethane in turn, stir for 10min, start to add 2.52kg of titanium tetrachloride dropwise, control the internal temperature to 20~30℃, and continue stirring 30min, continue to add 1.33kg of 1-(2,3-dimethylbenzene) ethanol dropwise under the temperature adjustment, after the drop is completed, continue to stir the reaction for 18h, take samples for TLC detection or HPLC detection. After the completion of the reaction, the reaction solution was added to 10L of ice water, stirred for 20min, left to stand for stratification, the aqueous phase and the organic phase were separated, the organic phase was discarded, the pH of the aqueous phase was adjusted to 10 with sodium hydroxide, and 12L of dichloromethane was added for extraction. , separate the organic phase, add 4L of dichloromethane to the aqueous phase again for extraction, and combine the organic phases. The organic phase was dried with anhydrous sodium sulfate, filtered, and the filtrate was concentrated to dryness under reduced pressure to obtain 2.23 kg of a yellow oily liquid, which was a crude product of medetomidine, with a yield of 89.9%.
2) Refinement of medetomidine
In the 30L dry glass reaction kettle, add 2.23kg of medetomidine crude product successively, 22.3L of dehydrated alcohol and 0.65kg of L-(+) tartaric acid, stir and heat up to make the solids dissolve completely, turn off the heating, naturally cool down and stir, and crystallize 10h, filter, collect the solid, add the obtained white solid to 22.3L of dichloromethane and 5.6L of water, stir, add sodium hydroxide, adjust the pH to pH 10, stir for 15min, stand for stratification, separate the organic phase, add no The water was dried over sodium sulfate, filtered, and the filtrate was concentrated to dryness under reduced pressure to obtain 1.56 kg of yellow oily liquid, which was a refined product of medetomidine, and the yield was 70.0%.
3) Preparation of Dexmedetomidine
In the 50L dry glass reactor, add 1.56kg of refined medetomidine, 31.8L of dehydrated alcohol and 0.42kg of L-(+) tartaric acid successively, stir and heat up to make the solids dissolve completely, turn off the heating, and naturally cool down to room temperature , crystallized for 10h, filtered, and the solid was collected. The obtained white solid was added to 31.8L of dichloromethane and 10.6L of water, stirred, added with sodium hydroxide, adjusted to pH 10, stirred for 15min, left to stand for stratification, and the organic phase was separated. , was dried by adding anhydrous sodium sulfate, filtered, and the filtrate was concentrated to dryness under reduced pressure to obtain 0.47kg of white solid, which was dexmedetomidine.
4) Preparation of Dexmedetomidine Hydrochloride
0.47kg of dexmedetomidine was added to 9.4L of dichloromethane, stirred to dissolve all the solids, and after the solution was clear, 390ml of 9N hydrochloric acid ethanol was added dropwise. 37.6L of petroleum ether was added dropwise, and a large amount of white solid was precipitated. After the drop was completed, stirring and crystallization was carried out for 2 h, suction filtration, and the filter cake was blast-dried to constant weight to obtain 0.54 kg of dexmedetomidine hydrochloride, with a total yield of 18.4 %.
