Lidocain Hydrochlorid Uses

  1. Lidocain Hydrochlorid has the characteristics of solid penetrability, strong dispersibility, and fast start of activity. The anesthetic efficacy is two times that of procaine, as well as the toxicity is 1.After absorption, it can hinder the main nerve system, hinder ventricular automaticity, shorten the refractory duration, and can be made use of to manage ventricular tachycardia and also treat arrhythmia symptoms such as ventricular premature beats, ventricular tachycardia and also ventricular fibrillation. It works for cardiovascular disease or cardiac arrhythmia brought on by cardiac glycosides, however not for supraventricular tachycardia. This product has a quick action, a short duration, and also is ineffective when taken orally. It is typically provided as an intravenous injection.
  2. Lidocain Hydrochlorid is an anesthetic. Big, improved impact or poisoning, anticonvulsant result at sub-toxic plasma focus.

Preparation of Lidocain Hydrochlorid

report one,
(1) Preparation of intermediate 2,6-dimethylaniline
24.43 g (0.2 mol) of 2,6-xylenol, 63.1 g (0.6 mol) of ammonia water, 1.06 g of 5% Pd/C, and 2.52 g (0.02 g of 2,6-dimethylcyclohexanone) were successively added to the reaction vessel. mol), reacted at 185 °C for 6 h, cooled to room temperature, filtered, recovered Pd/C and applied; the filtrate was distilled under reduced pressure, recovered 2,6-dimethylcyclohexanone and applied next time, the residue was washed with water once, and left to stand for stratification. , the oil layer is the intermediate 2,6-dimethylaniline 23.35g, the HPLC purity is 98.32%, and the yield is 94.73%.

(2) Preparation of Lidocain Hydrochlorid
To the there-necked flask with the distillation device, add 15.12g (0.28mol) of sodium methoxide, 24.24g (0.2mol) of the intermediate 2,6-dimethylaniline and 31.9g (0.22g) of N,N-diethylaminoacetate methyl ester successively. mol), heated to 95°C, and the methanol generated by the reaction was distilled off while reacting, until no methanol was evaporated, continued the reaction for 30 min, cooled to room temperature, added dichloroethane to dissolve, washed twice with water, and allowed to stand for stratification. The organic layer is the dichloroethane solution of lidocaine base.

In the dichloroethane solution of above-mentioned lidocaine base, add hydrochloric acid 2.56g, then adjust the pH to 3.5 with hydrogen chloride, add activated carbon to reflux for 20min, filter, concentrate the filtrate, crystallize by cooling, and dry to obtain Lidocain Hydrochlorid 48.28g, HPLC purity was 99.52%, the yield was 88.72%, and the total yield was 84.04%.

report two,
(1) Add acetone 200L, 2,6-dimethylaniline 50.0kg (412.6mol), potassium carbonate 142.6kg (1031.5mol) to the 500L enamel reaction kettle, stir and adjust the temperature of the material to 20±5°C, keep at Within this temperature range, 48.9 kg (433.2 mol) of chloroacetyl chloride was added dropwise at a high position, and the reaction was stirred at this temperature for 0.5 h after the dropping. Add 33.2kg (453.9mol) of diethylamine, heat to 60±5°C for 8h, filter, add hydrochloric acid to the filtrate with stirring, and adjust the pH of the filtrate to below 4.

(2) Concentrate the above reaction solution under reduced pressure at 50±5°C until no liquid is evaporated, add 200L acetone, heat and dissolve completely, add 2kg activated carbon, stir and decolorize at 55~65°C for 0.5h, press filter to clean area Crystallization kettle, stirring and cooling for crystallization, cooling to below -5°C for 3h, shaking off for filtration, and vacuum drying at 40-50°C in double cones for 4h to obtain 93.4kg of white crystalline powder, yield: 78.38%, HPLC normalized purity: 99.84 %.

Precautions for Lidocain Hydrochlorid

(1) Those who are allergic to other local anesthetics may also be allergic to lidocaine hydrochloride.
(2) Use with caution in the following situations: pregnancy, neonates, especially premature infants, patients with reduced hepatic blood flow, liver and kidney insufficiency, congestive heart failure, severe myocardial damage, hypovolemia and shock.
(3) Strictly control the concentration and the total amount of medication, overdose can cause convulsions and cardiac arrest; its metabolism in the body is slower than that of procaine, and it has an accumulation effect, which can cause poisoning and convulsions.
(4) The dose for the elderly should be adjusted according to the needs and tolerance, and the dose should be halved for those over 70 years old.
(5) Prevent accidental entry into blood vessels during anesthesia and prevent local anesthetic poisoning.
(6) When treating arrhythmia, attention should be paid to monitoring blood pressure, electrocardiogram, and rescue equipment; if the P-R interval of electrocardiogram is prolonged or the QRS wave is widened, and other arrhythmias occur or the original arrhythmia is aggravated, the drug should be discontinued immediately.
(7) During anesthesia, the P-R interval of the electrocardiogram is prolonged or the QRS wave is widened, and the drug should be discontinued immediately if other arrhythmias occur or the original arrhythmia is aggravated.

Lidocain Hydrochlorid Drug Interactions And Adverse Reactions

Drug Interactions:

(1) Cimetidine as well as β-blockers can hinder the metabolic rate of lidocaine in the liver and increase the blood concentration, which can trigger negative reactions of the heart as well as nerves. The dosage of lidocaine hydrochloride must be readjusted. (2) Barbiturates can advertise the metabolic process of Lidocain Hydrochlorid, and the mix of the two medicines can create bradycardia and sinus arrest.
( 3) Mix with procainamide can generate transient delirium as well as hallucinations, however does not impact the plasma concentration of this item.
( 4) Isoproterenol can enhance the complete clearance price of this item by raising the hepatic blood flow; norepinephrine can decrease the overall clearance price of Lidocain Hydrochlorid by minimizing the hepatic blood flow.
( 5) Conflict with the following drugs: phenobarbital, thiopental sodium, sodium nitroprusside, mannitol, amphotericin B, ampicillin, sulfadiazine.

Adverse Reactions:

The incidence of damaging responses of Lidocain Hydrochlorid has to do with 6.3%. Most negative reactions are dose-related. Damaging responses include drowsiness, wooziness, vertigo, queasiness, vomiting, lethargy, euphoria, complication, muscle twitches, convulsions, blurred vision, complication and also dyspnea. Big dosages can create severe sinus bradycardia and also heart arrest., Serious atrioventricular block as well as deteriorated myocardial contractility, blood pressure and so forth.

Extreme focus of Lidocain Hydrochlorid in the blood can create slowing of atrial conduction velocity, atrioventricular block (A-V-B), as well as inhibition of myocardial contractility as well as decreased heart result. A few have allergies such as erythematous breakout as well as angioedema.
