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.

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

Cyclohexanone is an organic compound with the formula C6H10O , a saturated cyclic ketone with carbonyl carbon atoms included in a six-membered ring. Colorless transparent liquid with earthy smell, with mint smell when containing trace amounts of phenol. Impurities are light yellow, which develop color with the formation of impurities during storage time, and are water-white to gray-yellow, with a strong pungent odor. Mixed with air, the explosive pole is the same as open-chain saturated ketone.

N,N-dimethylformamide is an organic compound with the formula C3H7NO and is a colorless transparent liquid. It is not only a chemical raw material with a wide range of uses, but also an excellent solvent with a wide range of uses.

In 1929, Daim discovered that there are two kinds of vitamin K in nature, K1 and K2, both of which are naphthoquinone compounds. Vitamin K2 is a naturally occurring vitamin containing the basic structure of menaquinone and has anti-bleeding effects, yellow crystal or oily liquid at room temperature, insoluble in water, soluble in organic solvents and vegetable oils, heat-resistant, but easy to be damaged by light. It can promote the synthesis of prothrombin in the liver and regulate the synthesis of coagulation factors VII., IX., and X., thereby accelerating blood clotting.
