氯甲左箭毒是氯化双甲基氧(醚链)左旋箭毒碱(dimethyl-oxy-levo-curine chloride)的简称,是从防已科植物的Cyclae hainaneusia Merr的茎或Cyclae barbara(Well)Mjers的根等提炼所得,化学结构已经查明,1978年即证实是一非去极化亦即竞争性肌松药,针剂亦于该年开始有供应,现已批量生产。 已知筒箭毒(氯化右旋筒箭毒碱的筒称)针剂并不很稳定,过去我院购得后,经4℃贮存了二年许均失效。已知氯化双甲基氧筒箭毒碱,商品名Metubine,是前者的甲基醚,理化性质比较稳定,对酸碱值的改变影响也小些。
Chlormelazine is an abbreviation of dimethyl-oxy-levo-curine chloride, which is derived from the stem of Cyclae hainaneusia Merr which is an anti-family plant, or Cyclae barbara (Well ) Mjers’s roots and other refined derived, the chemical structure has been identified in 1978 that is a non-depolarized that is competitive muscle relaxants, also began to supply in that year, has been mass-produced. It is known that myotoxin (a standard for chlorothalonucleosides) is not very stable. In our hospital in the past, after two years of storage at 4 ° C, all of them were ineffective. It is known that metoclomidine chloride, a trade name of Metubine, is the former methyl ether. Its physical and chemical properties are relatively stable, and its influence on the change of pH value is also small.
