水是一种广泛应用于药剂中的化合物,很少制剂中不含有它。自来水虽然合乎卫生、适于饮用,但在化学上是很不纯粹的。英国药典1958年版规定纯水除注射液外,可用于任何的制剂。如果制剂的成分与水中的杂质不发生配伍禁忌,应用饮料水来制备内服和外用的制剂是经济而合宜的。不过各地所供应的饮料水的质量是大不相同的,因此,制成的制剂的外观上及质量上都不一致。 Water is a compound widely used in pharmaceuticals, few of which do not contain it. Although tap water is hygienic and suitable for drinking, it is not chemically pure. British Pharmacopoeia 1958 Edition provides pure water injection, can be used for any preparation. If the ingredients of the formulation and water impurities do not appear incompatible taboo, the use of beverage water to prepare oral and topical formulations is economical and appropriate. However, the quality of the beverage water supplied varies widely and, therefore, the formulations produced are not uniform in appearance and quality.
