Pharmacology and toxicologyWhen the plasma concentration exceeds 5 μg·mL-1, convulsions can occur, and at low doses, it can promote the outflow of K+ in myocardial cells, reduce the auto-discipline of the myocardium, and have anti-ventricular arrhythmic effect; At therapeutic doses, there is no significant effect on the electrical activity of cardiomyocytes, atrioventricular conduction and contraction of myocardium; Further increase in blood concentration can cause slowing of cardiac conduction velocity, atrioventricular block, inhibition of myocardial contractility and decrease of cardiac out

Pharmacology and toxicologyThis product is an amide local anesthetic. After blood absorption or intravenous administration, it has obvious excitation and inhibition biphasic effect on the central nervous system, and there can be no precursor excitement, when the blood concentration is low, analgesia and drowsiness, and the pain threshold is increased; With the increase of dose, the effect or toxicity increases, and there is an anticonvulsant effect at the concentration of subtoxic blood drugs; When the blood concentration exceeds 5 mg·mL-1, convulsions can occur.

Fields of applicationPurpose 1It is suitable for vitamin B1 deficiency, has the function of maintaining normal glucose metabolism and nerve conduction, and is also used for the adjuvant treatment of dyspepsia and neuritisPreparation method:Method 1Thiamine hydrochloride is usually obtained by condensation, hydrolysis, neutralization, oxidation, and acidification of excess acetamidine hydrochloride with α-dimethoxy β-methoxypropionitrile.Upstream and downstream product informationUpstream raw materialsEthanol, hydrogen peroxide, dimethyl sulfate, ethyl chlorosulfonate, acrylonitrile, carboxylat

Pharmacological actionSince the discovery that long-acting local anesthetics can induce cardiac arrest, people have been looking for safer alternatives with less fat solubility. Ropivacaine is such a new long-acting amide local anesthetic, which has a long duration of action and has anesthetic and analgesic effects. Its pharmacological characteristics are low cardiotoxicity, sensory block and motor block are clearly separated, and it has peripheral vasoconstriction effect.
