Gentamicin is one of the commonly used antibiotics in small animal practice in Nigeria. Fake and substandard drugs are responsible for high cost in both economic terms and lives lost. For decades, Nigeria has been flooded by counterfeit and poor-quality medicines. Because of the variations in gentamicin C components in different formulations and the effect of this on its efficacy and toxicity, this study was designed to evaluate the percentage of each of the major components of gentamicin C in some injectable gentamicin sulphate generics commonly used in small animal practice in Nigeria. Of the 22 multisource generics of injectable gentamicin sulphate samples analyzed for percentage content of gentamicin C major components using USP HPLC （United States Pharmacopoeia high performance liquid chromatography） method, 95.5% （21 ） met the USP specification. This suggests that there is a significant improvement in the monitoring of quality of drugs marketed in Nigeria, including gentamicin sulphate. Nevertheless, considering the propensity of the manufacturers adjusting their manufacturing processes following product＇s registration by the regulatory body, there is still the need for regular surveillance of drug products by batches to ensure their efficacy and safety.

Journal of Pharmacy and Pharmacology 2014年第2期2卷 135-139页

Albendazole is a benzimidazole derivative with broad spectrum of activity against nematodes and cestodes infections in animals. Bulk of the needed drugs in West African sub-region is imported and adulteration in drug trade is common. This study was aimed at examining the quality of nine brands of veterinary albendazole boluses commonly used in Nigeria. Bolus weight uniformity, assay, hardness, friability, disintegration time, and dissolution profiles of the brands （250 mg/bolus） were tested according to the official specifications. All the brands tested failed bolus weight uniformity test except brands C and H. The percent albendazole in brands A, B, C and F were within official specification whereas D, E, G, H and I failed. None of the brands passed hardness test. All the products passed friability test except brand E. All the test brands disintegrated within the specified time except B and H. Only brands B, C, E and I passed the dissolution test. Consequently, only brands B and C could be interchanged with the reference. There is need for routine quality control and post market surveillance of veterinary drugs in Nigeria.
