Brachystegia eurycoma seed mucilage was evaluated for use as a tablet binder in metronidazole formulations in comparison with gelatin. The granules were formulated by the wet granulation method using the extracted mucilage and gelatin as binder at 1, 2, 4, 6%w/w concentrations. The granules were found to possess good flow property as indicated by the angle of repose, Hausner’s ratio and Carr’s index. The formulated tablets were evaluated for uniformity of weight, thickness, tablet hardness, friability, disintegration times, drug assay and dissolution profile. Generally, the tablets formulated from Brachystegia eurycoma seed mucilage were softer than those of gelatin, had good uniformity of weight and disintegrated within the official specified times for uncoated tablets. The tablets had a rapid dissolution rate which indicates the efficacy of Brachystegia eurycoma seed mucilage as a binder where fast release of a drug is desired.Download Full Material-N5000

CHAPTER ONE
1.0 INTRODUCTION
1.1 Background
Lead is a heavy, low melting, bluish-gray metal that occurs naturally in the Earth’s crust. However, it is rarely found naturally as a metal. It is usually found combined with two or more other elements to form lead compounds. For these reasons, lead has been used by humans for millennia and is widespread today in products as diverse as pipes, storage batteries, pigments and paints, glazes, vinyl products, weights, shot and ammunition, cable covers, and radiation shielding. Tetra-ethyl lead was used extensively from the 1930s to the 1970s as a petrol additive to improve engine performance (Rosner and Markowitz, 1985; Landrigan et al., 2002). Tetra-ethyl lead has been eliminated from the petrol supplies of the majority of countries, but is still used in about nine countries (UNEP, 2008).
Lead poisoning (also known as Plumbism, Colica Pictonum, aturnism, Devon colic, or painter’s colic) is a medical condition in humans and other vertebrates caused by increased levels of the heavy metal lead in the body (Washington, 2011). Lead interferes with a variety of body processes and is toxic to many organs and tissues including the heart, bones, intestines, kidneys, reproductive and nervous systems. It interferes with the development of the nervous system and is therefore particularly toxic to children, causing potentially permanent learning and behaviour disorders. Symptoms include abdominal pain, confusion, headache, anemia, irritability, and in severe cases seizures, coma, and death (Washington, 2011).Download Full Material-N5000
