The spectrophotometric and microbiological assay methods used for the determination of ampicillin
levels in ampicillin/cloxacillin combinations were compared. A total of 24 samples of am picillin/cloxacillin
suspensions from 8 batches and 3 companies (B2, D and E) were assayed for their ampicillin content levels
using the Spectrophotometric assay method. Infra-red (IR) Spectroscopy confirm ed the presence of ampicillin
in all the samples and the results obtained showed that the samples had a wide range of amounts of ampicillin
which compared favourably w ith the microbiological assay results of the sam e products. A ll the products
assayed had ampicillin content within acceptable ranges of the BP and USP. Spectrophotometric assay is
recommended for the quick determination of the levels of ampicillin in their combinations with cloxacillin.
Key words: Ampicillin, cloxacillin, Infra red, spectrophotometric assay, spectroscopy, ,
