Abstract
Object of present investigation was to develop and characterize such a gastroretentive tablet, which provides the synergism effect of adhesiveness and floating property for prolonged release of 5-flourouracil within the stomach. The floating mucoadhesive tablets were prepared by the wet granulation method using different ratios of hydroxy propyl methyl cellulose (HPMC K4MCR) and Carbopol 934P as polymers. The prepared floating-mucoadhesive tables were characterized for hardness, detachment stress, floating properties, swelling index and surface morphology by SEM. The in vitro drug release and floating behaviour were studied in simulated gastric fluid (SGF) at pH 1.2. Different kinetic models for drug release were as well applied. Formulations of T-9 batch were furthermore subjected to stability and in vivo radiographic studies.
