Assessment of the Quality of Water for Injection Marketed in South-Eastern Nigeria

The present work seeks to evaluate the safety and quality of water for injection (WFI) marketed in south-Eastern Nigeria. The physical, microbiological and chemical qualities of different brands of WFI marketed in south- eastern Nigeria were evaluated in order to ascertain their quality. A total of one hundred and forty-seven (147) samples of four different brands of WFI (approximately thirty vials per state) were analysed. All the brands (A, B, and C) except D conformed to the PH range (5.0-7.0) at room temperature. The PH value of all the brands reduced when subjected to increased temperature. All the brands were also sterile. All the brands passed the conductivity test with respect to compendia standard. The study revealed that the various brands of WFI marketed in south-eastern Nigeria conform to some official limits except for heavy metals. However, WFI in south-eastern Nigeria are considerably safe.
