利多卡因与羟丁酸钠合用的经物动力学研究
的加八注射液的pH值有所升高,当p卜I在4.0~5.0时影响不太.而pH在6.0~7.0时升高明显。结论:在实际生产工作中要杜据活性发的加入量酌情增大苷硝哇的授八量;在不增加授八量的情况下.活性发的用量宜控制在0.05%左右,pH值宜控制在4.0~5.0之间关t词.!坚,兰!墨瘩:萄囊懒Effbctsofactivated17.arianOiltinidazoleglucoseinjectionXiongXiong,linCheng.GaoZhentong,etal(D印盯nn∞tofPharmacy.South—w酋tHcspital,theThirdMilitaryMedicalUni—versity,cl嘲400038)ABs1mAcTOBJECTIVE~Toinve~tigatetheeffectofactivatedcarbononboththec{mte~toftlnidazoleandoHvalueofdnid~olegIuo。seiT1jectionM匝T}I(1DSDifferentamountofacfivatedcarbonwasaddedtOtheiT1jecdonandWSITDedat80℃inwa0盯bathfor30rainandthenfiltered)thec{mte~tsofdnidazo[eandpHvalue哪deterIed.砌璐UIIs:TheexperimentshdWedthattheo曲1一tentoftinidazoledecreasedmarked[ywiththeincreasinguseofactivatedP..Bl'han,butnochar1geint}oDntof·o。.whdIpI-Ivaluewasben40~5.0.1essquantityoftirddazolew8,8absorbedbythecarbon;withtheaddingofactivatedcarbon.thepHvalueofsolutionincreased,whereasthepHvaluewouldchangeslightlywhthe~ginaloHvalueWaS~~ween40--5.0,onlyatpI-I60~70theireasew锯.O咖.i(1耵鲺C野Forthe印啪t_mdthe;玛刚0.05%ofthe出beused,tkpHdtheectionshouldbem丑inc8jnedwithin40~50.砌1Yw0RDsactivatedcarbu~,tinida∞Iej∞9e,absorption在配制替硝唑葡萄糖注射液的过程中,发现活性炭对替硝唑葡萄糖注射液的含量和pH值有明显的影响,即探讨了活性炭用量对替硝唑葡萄糖注射液的含量和pH值的关系,现报道如下:1仪器与试剂Du一70紫外分光光度计(美国Beckon公司);WZZ-旋光计(上海光学仪器厂);pH计(美国Beck—man公司);替硝唑(湖北广济药业股份有限公事,批号970313);葡萄糖(重庆制药五厂,批号981025);中国医院药学杂志1999年第19卷第5期767针剂活性炭(上海活性炭厂)。2测量方法2.1供试品配制称取替硝唑0.8g,萄萄糖11g,置瓶中,加水约1800ml溶解,用稀盐酸调pH约4.5,加水至2000ml,搅匀即得。2.2含量测定2.2.1替硝唑精密量取供试品3ml至100ml容量瓶中,蒸馏水稀释成每1ml含替硝唑12的溶液,依法在317nfn波长处测吸收度_2_2。·271-
