RESUMEN
Among the oral route, mouth dissolving tablets (MDTs) offer a benefit for drugs with slow dissolution and having low oral bioavailability. Epalrestat is one of the best effective diabetic neuropathy medication used for treating nerve pain. The problem associated with this drug is high first pass metabolism and low solubility in acidic media as well in basic media leads to short half-life, delayed dissolution and side effects. Therefore, the goal of the current work is to developed an epalrestat MDTs tablet that will provide quick drug dissolution and a quick onset of action for the treatment of nerve pain. MDTs of epalrestat were formulated by direct compression using natural superdis integrants obtained from the various sources such as fenugreek, gum karaya and banana powder. All of the pre- and post-compression parameter results were shown to be in accordance with established specifications. In comparison to other formulations of MDTs, formulation F3 with 15 mg (7.5%) of banana powder displayed a higher rate of dissolution. It was determined that epalrestat MDTs containing natural superdisintegrant were successfully formulated with acceptable physical and chemical properties, quick oral cavity disintegration, a quick onset of action and improved patient compliance.
