其实我们也是采取“第二次的复验期是第一次的一半,以此类推,不能无限期延长”(但是规定最多5次,不超过有效期),但是不知道出处。还有我看国外论坛有看到retest period的计算)选自:http://phdig.groupsite.com/discussion/topics/414372/messages作为参考讨论
Retest is simply nothing but re-analysis of the specimen.
it is the date, uptil you can use the material (it must be tested before use)
Retest is assigned based on accelerated stability data along with long term data.
Accelerated is the worst case condition to extend the retest date .
For Eg: if an API covered six months long term and six month accelered.
we give retest period of twelve months. this extention period is of alloting retest is based on accelered only.
other wise it should be six months only.
For retest, data from API manufactrer stability data should be supportive.
-------------------------------------------------------------------------------
Y=2X is
y= retest period
x= available long term data at 25 degrees and RH 65%.
(if x is greater than 12 months , use the formula Y=X+12 months.)
----------------------------------------------------------------------------------
(stored in refrigerator)
Y= 1.5 X months is
y= retest period
x= available long term data at 25 degrees and RH 65%.
(if x is greater than 12 months , use the formula Y=X+12 months.)
