Preparation Process for Water for Injection (WFI) in Pharmaceuticals

There are basically two types of water preparation in pharmaceuticals.Water for Injection (WFI) preparation process and Purified Water preparation process. The analytical standards for the two water are almost very similar, the only difference is that Water for Injection (WFI) system in pharmaceuticals has stricter bacterial control standards than purified water process and has to pass the bacterial endotoxin test. Preparation methods are very similar to a particular point, however, Water for Injection (WFI) preparation process in pharmaceuticals must include distillation or double pass reverse osmosis techniques. Water for Injection (WFI) preparation process in pharmaceuticals systems, involves several steps and processes this includes; dechlorination, ion reduction, bacterial control, and removal of specific impurities. Dechlorination: This refers to the removal of chlorine from the water. There are several ways of dechlorination.This include injection of a reducing agent lik...
