ABSTRACT

Introduction: Metronidazole is a synthetic oral nitroimidazole antibiotic used in the treatment of infections caused by anaerobic bacteria and protozoa. It also has amebicidal and antiprotozoal properties. Aim: The purpose of the study was to formulate and evaluate metronidazole tablets formulated with polymers (PVP and PEG) and maize starch as disintegrant using moisture activated dry granulation (MADG). Method: Twenty-four (24) batches of metronidazole granules and tablets were prepared by moisture activated dry granulation. Metronidazole (200 mg), lactose and gelatin (1,2,4 and 8 %) were mixed, followed by continuous mixing. Prior to compression, micro-crystalline cellulose, disintegrants and magnesium stearate were added. The dried granules were passed via 1.0 mm sieve after which they were labelled and stored in an air tight container. All other batches were also similarly prepared. Result: The result showed that the mean weight of the tablets ranged from 0.33 ± 0.01 to 0.35 ± 0.04 g. Tablet hardness ranged from 5.00 ± 0.85 to 6.36 ± 1.43. The results showed that batch 11 tablets had higher crushing strength than batch 24 with a significant difference. Table 2 shows the hardness test results and clearly indicates that the results of all the samples significantly differ from each other (p < 0.05). The tablet friability test ranged from 0.21 ± 0.17 for batch 24 and 0.60 ± 0.16 for batch 11. The formulated tablets showed average disintegration time ranges from 0.52 ± 0.01 to 14.03 ± 0.03. According to USP, the disintegration time must be in the range of 15 min for uncoated tablets, and 30 mins for film coated tablets. Conclusion: The study established that polyethylene glycol and polyvinyl pyrrolidone polymers had better dissolution profile than maize starch which has the best disintegration properties.
