| Atracurium besylate Usage And Synthesis |
| Skeletal muscle relaxant for anesthesia |
Atracurium Besilate is a kind of skeletal muscle relaxant used for general anesthesia; it is suitable for the muscle relaxation required in both the treatment of abdominal surgery and endotracheal intubation. Being same with most neuromuscular blocking agent, it can cause the release of histamine, the occurrence of skin flushing, transient hypotension, and occasional bronchospasm. Combination between atracurium besilate and inhalation anesthetic gases, such as an alkyl halide, isoflurane and halothane may enhance the neuromuscular blocking effects. Combination with aminoglycoside, polypeptide-class antibiotics, lithium salts, and quinidine or procaine mountain amine may enhance its role in nerve blocking. This product is not suitable to be used in combination with depolarizing muscle relaxants such as suxamethonium which is due to that it may cause prolonged complex blocking effect which is difficult to be reversed by anticholinergic enzyme drugs. Patients who are allergic to this drug should be disabled. It needs to be especially careful for applying this drug in patients of myasthenia gravis, neuromuscular disease, and severe electrolyte imbalance, because it can enhance the effects of other non-depolarizing agents. People suffering from severe cardiovascular disease are more sensitive to the atracurium besilate-induced transient hypotension so it is recommended to apply a slow and graded intravenous injection for administration. |
| Distinguish |
At room temperature, atracurium besilate is white-like to yellowish crystalline powder; it is hygroscopic, odorless, easily soluble in chloroform or ethanol, soluble in water, but insoluble in ether. (1) Take about 10 mg of the product, after adding dilute hydrochloric acid for 1ml to dissolve, add diluted potassium iodide testing solution drop wise, which generates a yellow precipitate. (2) Take this product, add 0.1mol L hydrochloric acid solution for preparing the solution of concentration being 50μg per 1ml; apply spectrophotometry approach (Chinese Pharmacopoeia 2000 edition of Appendix VI A) for determination with a maximum absorption in the 280nm wavelength. (3) The infrared absorption spectrum of this product should be consistent with the reference standard map. The above information is edited by the chemicalbook of Dai xiongfeng. |
| Examination |
Color of the solution Take 100 mg of this product, add 10 ml of water to dissolve it with which the solution should be colorless; if it exhibits some color, compare it with yellow No. 3 colorimetric solution; it should not have a deeper yellow color (Chinese Pharmacopoeia 2000 edition of Appendix IX A first method). Relative substance Take a certain amount of this product; add the mobile phase to make a solution of 1mg per 1 mL, as the test solution; take some amount of the accurate standard sample, add the mobile phase for dilution to make a solution of 50 μg per 1 ml as the control solution. Perform according to the specific content and determine under the following chromatographic conditions, take accurately 10 μl of the standard control solution and add into the liquid chromatography; adjust the checking sensitivity and make the height of major component peaks being 20% to 25% of that of full scale; then accurately take 10 μl of the two above solutions and separately inject it into the liquid chromatography, record the test solution chromatograms until reaching 2-fold major component peak retention time. If there exist impure peaks at the chromatogram of the test solution, measure the sum of the amount of every impure peak area; the sum should not be larger than the peak area of the major component of the control solution (5.0%). Sulfate Take 1.0 g of this product, add water 30ml to dissolve it, check it according to inspection(Chinese Pharmacopoeia 2000 edition of Appendix VIII B); compare it with the control solution made by 5.0 mL of standard potassium sulfate solution, and should not be thicker (0.05%). Loss on weight by drying Take some amount of this product with phosphorus pentoxide as a desiccant, dry under vacuum at 50 °C for 3 hours with the losing weight should not exceed 2.0% (Chinese Pharmacopoeia 2000 edition of Appendix VIII L). Ignition of residue Take 1.0 g of this product, check it according to inspection (Chinese Pharmacopoeia 2000 edition of Appendix VIII N), the left residue should not be over 0.1%. Heavy Metal Take the residue of ignition and check it according to inspection (Chinese Pharmacopoeia 2000 edition Appendix VIII H method); the heavy metals content should not exceed twenty millionths. |

| Production methods |
Dissolve 0.1mol of 1, 5-pentanediol, 0.2 mol of triethylamine and 0.1g of pyrogallol in 100ml of dry benzene; further add 0.2 mol of acryloyl chloride for dissolution in 60 ml dry benzene solution under vigorous stirring. Then add about 100ml of anhydrous benzene and 10ml of triethylamine, followed by stirring at 50 °C for 0.5h; filter to remove the triethylamine hydrochloride, also remove the solvent under reduced pressure. In the presence of trace amount of p-methoxyphenol, the remaining yellow oil is distilled at darkness; further collect the distillate fraction of 90~95 °C/1.33Pa to obtain 1,5-pentamethylene diacrylate with yield being 61%. Dissolve 4.43g of tetrahydropapaverine and 1.30 g of the above 1, 5-pentamethylene diacrylate in 15 ml of dry benzene; stir in the darkness and reflux for 48h; further remove the solvent under reduced pressure with the remaining dark red oil being dissolved in 10ml of chloroform. Add about 400ml of diethyl ether; then further add about 500 ml of saturated oxalic acid into ether solution to give flocculent white precipitate. Filter, wash with ether, and dry. Re-crystallize using ethanol twice to give 3.5 g of compound as a white powder (I) in a yield of 51%, m.p. 117~121 °C. Compound (I) is dissolved in aqueous sodium bicarbonate solution and extracted with toluene. Concentrate the extract to obtain a colorless viscous liquid, which corresponds to compound (II). 0.5g of dry compound (II) is dissolved in 8 ml spectroscopically pure acetonitrile; add methyl benzenesulfonate, and have reaction at room temperature for 22h. Under vigorous stirring, add the solution drop wise into about 450 ml of dry ether. Filter and collected the formed flocculent white precipitates; wash with dry diethyl ether; In the presence of phosphorous pentoxide, dry it in vacuum at 50 °C to obtain white-like atracurium besilate powder with the melting point being 85~90 °C. |
