Present study aspires at the design of an immediate release formulation with prospective use of fexofenadine hydrochloride by exploring the effect of sodium starch glycolate as super disintegrant. Fexofenadine hydrochloride immediate release tablets (Formulations F-1, F-2, F-3, F-4 and F-5) using different ratios of sodium starch glycolate as a disintegrant were prepared by direct compression method. Standard physicochemical tests were performed for all the formulations. Dissolution studies of the formulations were done in phosphate buffer, pH 6.8 using USP apparatus II (paddle apparatus) at 50 rpm. Percent release of fexofenadine hydrochloride of formulations F-1, F-2, F-3, F-4 and F-5 were 89.98%, 90.98%, 92.95, 96.92% and 99.85%, respectively after 1 h and the release pattern followed the zero order kinetics. The release rate in the formulation F-5 was higher compared to other formulations and the studied market products. Sodium starch glycolate speed up the release of the drug from the core tablets, and the release of fexofenadine hydrochloride from tablets was directly proportional to the amount of sodium starch glycolate present in the formulations and there by produced immediate action.

The purpose of this study was to investigate the efficiency of superdisintegrants: sodium starch glycolate, croscarmellose sodium and crospovidone in promoting tablet disintegration and drug dissolution of Topiramate immediate release tablets. The efficiency of superdisintegrants was tested, by considering four concentrations, viz., like 2%, 3%, 4% and 5% in the formulations. The dissolution was carried out in USP apparatus II at 50 rpm with distilled water as a dissolution medium. The dissolution rate of the model drug topiramate was found highly dependent on the tablet disintegration, on the particle size of the superdisintegrant, on the solubility of the drug and also on the type of superdisintegrant in the dissolution medium. There was no effect of the diluent (Lactose monohydrate) on the disintegration of different concentrations of superdisintegrants. These results suggest that, as determined by the f2 metric (similarity factor), the dissolution profile of the formulation containing 4% sodium starch glycolate and lactose monohydrate as a diluent was similar to that of a marketed product.

Objective: The aim of the present study was to prepare and optimize levamisole chewable tablets by using various super disintegrants, namely; sodium starch glycolate, DRC Indion 204, and DRC Indion 234. Methods: Drug excipient compatibility study was carried out by FTIR spectroscopy to verify the compatibility of levamisole with the excipients. Nine batches of levamisole chewable tablets were prepared according to 32 factorial designs using a direct compression method by optimizing the super disintegrant concentration. The powder blend was exposed to pre-compression studies of the powder blend followed by post-compression studies of the formulated tablets. Results: FTIR study revealed that the excipients used in the formulations were compatible with the drug. The pre-compression and post-compression parameters were found within the IP limits. Form the dissolution studies, it was evident that the formulation prepared with DRC Indion 234 (50 mg) showed maximum percentage drug release in 45 min (97.13%) hence it is considered as optimized formulation. When compared to all other formulation, the batches with DRC Indion 234 (F7-F9) showed a better release of the drug (90 % drug release within 45 min). Conclusion: Nine batches of levamisole chewable tablets were successfully formulated by optimizing the concentration of super disintegrants such as sodium starch glycolate, DRC Indion 204, and DRC Indion 234. It was concluded from the dissolution studies that the DRC Indion 234 is the best super disintegrant irrespective of their concentration for the formulation of levamisole chewable tablets when compared to sodium starch Glycolate and DRC Indion 204.

Sustained Release Tablets

This work aims at the design of a sustained release formulation of glimepiride which is currently available in the treatment of type 2 diabetes mellitus and to investigate the effect of polymers on the release profile of glimepiride. Glimepiride sustained release tablets were prepared by direct compression method using different ratios of various release retarding polymers such as carbopol, ethyl cellulose, methocel K4 MCR, methocel K15 MCR, methocel K100 MCR and xanthum gum. These formulations were also compared with glimepiride immediate release tablets. The prepared tablets were subjected to various physical parameter tests including weight variation, friability, hardness, thickness, diameter, etc. In vitro dissolution studies of the formulations were done at pH 6.8 in phosphate buffer using USP apparatus 2 (paddle method) at 50 rpm. The percent releases of all the formulations (30) were 73.11%- 98.76% after 8 hours. The release pattern followed zero order kinetics and the release of the drug was hindered by the polymers used in the study. On the other hand, 100% drug was released within 1 hour from the immediate release tablet of glimepiride. The study reveals that the polymers used have the capacity to retard the release of the drug from the sustained release tablets and the more is the amount of the polymer in the formulation the less is the release of drug showing more retardation of drug release.Bangladesh Pharmaceutical Journal 18(2): 157-162, 2015

Objective: To synthesize, characterize and evaluate starch valerate as a superdisintegrant in the formulation of aceclofenac fast dissolving tablets by employing 23 factorial design. Methods: Starch valerate was synthesized and its physical and micromeritic properties were performed to evaluate it. The fast dissolving tablet of aceclofenac was prepared by employing starch valerate as a superdisintegrant in different proportions in each case by direct compression method using 23 factorial design for evaluation of tablet parameters like disintegration and dissolution efficiency in 5 min. Results: The starch valerate prepared was found to be fine, amorphous and free flowing. Starch valerate exhibited good swelling in water with swelling index (125.2%). The study of starch valerate was shown by fourier transform infrared spectra (FTIR). The drug content (200±5%), hardness (3.5–4 kg/sq. cm), and friability (<0.15%) has been effective with regard to all the formulated fast dissolving tablets employing starch valerate. The disintegration time of all the formulated tablets was found to be in the range of 14±0.04 to 25.7±0.02 sec. The optimized formulation F4 had the least disintegration time i.e., 12.8±0.02 sec. The wetting time of the tablets was found to be in the range of 76±0.21 to 217±0.17s. The In vitro wetting time was less (i.e., 28±0.02s) in optimized formulation F4. The water absorption ratio of the formulated tablets was found to be in the range of 46±0.12 to 100±0.27%. The percent drug dissolved in the optimized formulation F8 was found to be 99.93% in 5 min. Conclusion: Starch valerate, when combined with sodium starch glycolate, croscarmellose sodium, with aceclofenac, was found to be an effective super disintegrant which improved the dissolution efficiency and could therefore be used in the formulation of quick dissolving tablets to provide immediate release of the contained drug within 5 min.
