The U. S. [United States] Pharmacopoeia(USP) has three general specifications for water quality that are applicable to medical and pharmaceutical uses, namely ’USP Water for Injection’(WFI), ’USP Purified Water’(PW) and ’Drinking Water. ’… WFI requires the removal of a subgroup of endotoxins that are lipopolysaccharides(material that makes up the cell wall of Gram-negative bacteria and can cause an immune system response and fever termed "pyrogens"). … Thus, pyrogen-free water is a critical aspect of parenteral drug manufacturing.
