title: Formulation and in vitro evaluation of ketoprofen fast-dissolving tablets.
abstract: Drugs exhibiting satisfactory absorption from the oral mucosa or intended for immediate pharmacological action can be advantageously formulated as orally fast-disintegrating tablets (FDTs or ODTs). Therefore, taste masking of active ingredients becomes essential in these systems because the drug is entirely released in the mouth. Despite advances in the FDT technologies, formulation of drugs with a bitter taste is still a challenge, especially when the amount of drug is high. In this study, a new solution is being developed to incorporate higher doses of a model bitter taste drug; ketoprofen, without affecting the fast-disintegrating properties of the formulation. The unpleasant taste of the active drug usually masked by adding flavoring ingredients and sweeteners to improve taste and palatability but in this study a novel approach of using a polymer; Eudragit EPO and a granulation procedure of this polymer with the active drug was applied to mask the bitter taste of ketoprofen. In order to produce ketoprofen FDT formulations, a two-stepped procedure was followed; granulation process with the taste-masking agent (Eudragit EPO) and then direct compression (F3 and F4). In F1 and F2 formulations, granulation process was not implemented in order to observe the effect of application method of Eudragit EPO. As well as observing the effect of taste-masking agent, crospovidone and sodium starch glycolate were used in different concentrations (2, 4 and 8wt%) to examine the influence of superdisintegrants on FDT properties. All the FDTs containing 30 mg ketoprofen (F1, F2, F3 and F4) were evaluated by means of in vitro quality control tests.
