Fast Disintegrating Tablet

Objective: The aim of the present investigation was to design and evaluate orally disintegrating tablet (ODT) of Ibuprofen, a NSAID drug used for the treatment of arthritis with a view to improve its oral bioavailability. The focus of the current study was to develop ODT of Ibuprofen using super disintegrants for ease of administration and its physicochemical characterization.Methods: Tablets were made from blends by direct compression method. All the ingredients were passed through mesh no. 80. All the ingredients were co-ground in a pestle motor. The resulting blend was lubricated with magnesium stearate and compressed into tablets using the Cadmach single punch (round shaped, 8 mm thick) machine.Results: Physicals parameters of the prepared tablets like Hardness, Weight variation, Friability, thickness, drug content etc. found within the limits. The disintegration time of prepared ODTs was in the range of 45 to 55 seconds. In vitro dispersion time was found to be 22 to 52 seconds which may be attributed to faster uptake of water due to the porous structure formed by super disintegrants. Short disintegration and faster release of ibuprofen were observed with Cross carmellose sodium as compared to sodium starch glycollate.Conclusion: It is concluded that F3 offered the relatively rapid release of Ibuprofen when compared with other formulations. The increase in the concentrations of super disintegrants may lead to increase in the drug release. The formulation prepared with cross carmellose sodium was offered the relatively rapid release of Ibuprofen when compared with other concentrations of both the super disintegrant.

Formulation Variables

Simvastatin is a well established oral antihypercholesterolemic agent. This study aimed to formulate simvastatin as orodispersible tablets. The drug was incorporated as a solid dispersion using Pluronic® F68 as carrier. Croscarmellose Na was used as superdisintegrant, microcrystalline cellulose as filler, PVP K-30 as binder and 1:1 magnesium stearate/talc mixture as lubricant. Box- Behnken design was adapted to explore the main and interaction effects of three independent formulation variables on the prepared tablets, namely superdisintegrant concentration (X1), lubricant mixture concentration (X2), and binder concentration (X3). A total of 13 tablet formulations were fabricated in addition, to two replicates of the center point to assess variability and experimental error. The selected dependant variables were the<em> in vitro</em> and <em>in vivo</em> disintegration times, dissolution rate at 4 min, and dissolution efficiency after 30 min. Wetting time, drug content, hardness and friability were also evaluated. Tablet formula, composing of 12% superdisintegrant, 2% lubricant mixture and 3% binder, showed the highest dissolution rate with an acceptable disintegration time (43 sec), hardness, and friability and was chosen as the best formula. An accelerated stability study was conducted for 6 months at 40°C/75% RH. Results showed no significant changes in any of the tested parameters.
