国外化学原料药一般用“复验期”。
下面是Q7原文:
Re-test period
The period of time during which the drug substance is expected to remain within its
specification and, therefore, can be used in the manufacture of a given drug product,
provided that the drug substance has been stored under the defined conditions. After
this period, a batch of drug substance destined for use in the manufacture of a drug
product should be re-tested for compliance with the specification and then used
immediately. A batch of drug substance can be re-tested multiple times and a
different portion of the batch used after each re-test, as long as it continues to comply
with the specification. For most biotechnological/biological substances known to be
labile, it is more appropriate to establish a shelf life than a re-test period. The same
may be true for certain antibiotics. |
