盐酸山莨菪碱(简称654-2)注射液的含量测定,就目前国内现行方法中,原料采用中和法;其针剂、片剂及其中间体和半成品则采用非水滴定法。我们通过长期生产实践,发现非水滴定法测定该注射液含量偏低,即方法本身回收率低。我们经参阅有关资料,对该产品的注射液含量测定进行方法改进。因该注射液生产处方中有盐酸和氯 Determination of anisodamine hydrochloride (referred to as 654-2) injection, the current domestic methods, the raw materials used in the law; its injections, tablets and intermediates and semi-finished products are non-aqueous titration. Through long-term production practices, we found that non-aqueous titration of the injection content is low, that is, the recovery rate of the method itself is low. We refer to the relevant information, the injection of the product content determination method for improvement. Because of the injection production of hydrochloric acid and chlorine in the prescription
