注射剂的PH值一般控制在多少为什么

溶液型注射剂确定PH值要用酸度计的,注射剂因为要注入人体所以最重要的是要制成等渗溶液或等张溶液,要测定摩尔渗透压的,

您好亲
前面的0.5使药物含量,后面的1.0是质量,祝您愉快.还望您采纳,谢谢

6岁孩子的体重大约是20公斤,如氨茶碱小儿剂量为每次2~4mg/kg,氨茶碱每支0.25g/10ML的话,可每次抽取2毫升或3毫升应用．但静脉注射时候要葡萄糖稀释后30分钟内注入．如还有疑问,发消息给我．

一般使用氯化钠,焦亚硫酸钠一股作为抗氧化剂,枸椽酸钠一般为PH调节剂,羧甲基纤维素一般为片剂的黏合剂、崩解剂,混悬剂的助悬剂

设定115℃*30min灭菌程序,温度范围应该在115-117℃波动,所以探头显示基本在116摄氏度是正常的.

This paper mainly studies the preparation encapsulation efficiency in more than 80% of hydrochloric acid doxorubicin liposomes injection,and has certain stability.This injection by doxorubicin or hydrochloric acid doxorubicin,neutral lecithin phospholipid and negative and cholesterol,antioxidants,organic acid,alkali,slow granule,injection water,this preparation techniques including blank homogenization liposome,liposome,preparation doxorubicin or hydrochloric acid doxorubicin liposomes and its suspension liquid,the capacity,aseptic,repacking,steps and preservation of liposome of hydrochloric acid doxorubicin for the determination of encapsulation efficiency.This injection good stability,encapsulation efficiency high,low cost,fewer side effects,the preparation technology is simple.
This paper studies using pH gradient legal prepare liposomes adriamycin.Through the nano technology,made by adjusting after nanometer sac capsule inside and outside the concentration of the ions pH value,loading hydrochloric acid doxorubicin,make doxorubicin outside into the nano from sac,and sac within the capsule total adriamycin,the proportion of adriamycin lower than 20%

解题思路：有机物中含酚-OH、醇-OH、C=C、-CO-、-COOC-，结合酚、烯烃、醇、酯的性质来解答．

A．含酚-OH，与溴水在邻位发生取代反应，C=C与溴水发生加成反应，则1mol最多能和含3mol Br₂的浓溴水反应，故A正确；
B．由结构可知，“亮菌甲素”的分子式为C₁₂H₁₀O₅，故B正确；
C．苯环及C=C、-CO-能与氢气发生加成反应，1mol该物质最多能和5molH₂发生加成反应，故C错误；
D．酚-OH、-COOC-能与NaOH反应，且水解生成的酚-OH也反应，则1mol“亮菌甲素”能与含3molNaOH的溶液完全反应，故D正确；
故选C．

点评：
本题考点： 有机物分子中的官能团及其结构；有机物的结构和性质．

考点点评： 本题考查有机物的结构与性质，注意把握有机物官能团与性质的关系来解答，熟悉酚、酯、烯烃的性质是解答的关键，题目难度不大．
