Abstract

he antimicrobial activity of five brands (A, B, C, D and E) of ciprofloxacin hydrochloride tablets commonly sold in Lagos Nigeria, were compared and assessed against susceptible clinical isolates (Staphylococcus aureus, Escherichia coli and Salmonella enterica serotypetyphi). Susceptibility test, minimum inhibitory concentration test and the bactericidal activity were determined. All sampled brands were within their shelf life. Most (60%) of the sampled brands were made in India while the remaining 40% were made in Nigeria. All the brands complied with the official specification in British Pharmacopeia (BP) for uniformity of weight as they show less than 5% deviation in weight. The mean antibacterial activities of the brands at 25g/ml were found to be within the range of 38.0mm to 42.2mm zone of inhibition while the MICs range between 0.012g/ml to 1.5g/ml.

All the sampled brands were effective against all the test organisms to varying degree with brands A and E been more potent while brand D was the least effective. The order of MICs (decreasing order of potency) was D>B>C>A>E for Staphylococcus aureus and D>C>B>E>A for Escherichia coli while that of Salmonella enterica serotypeTyphiwas D>B>C>A>E. The bactericidal activity of each ciprofloxacin brand D and E are concentration-dependent; with brand E more active at all tested concentrations.
