6. FINAL TREATMENT OPTIONS: WATER FOR INJECTION (WFI)
终处理选择:注射用水
6.1 INTRODUCTION介绍
This chapter addresses the USP approved final treatment methods for the production of compendial
WFI.WFI is the purest grade of bulk water monographed by the USP and would be expected to be used for
the manufacture of parenteral, some ophthalmic and inhalation products, and for finishing steps of
parenteral grade active pharmaceutical ingredients (API's).本章着重介绍了USP批准的注射用水的终处
理方法,注射用水是USP中水的最高纯度等级,用于制备注射类药品、一些眼科及吸入类药品,并
用于注射级原料药(API's)的最后步骤。
recommended systems include either distillation or RO as the final processing step, but may also include
trafiltration (UF), deionization (Dl) and/or ion exchange (IX), to compliment the RO or distillation unit
operation.推荐使用蒸馏系统或反渗透系统作为水处理的最后步骤,同时还包括使用超滤、EDI来增强蒸馏系统或反渗透系统的效果。 |
