Fast disintegrating tablets (FDTs) dissolve or disintegrate in the mouth without the need of additional water. The aim of the present study was to formulate FDTs of Valsartan for the treatment of hypertension in children who could find difficulties in swallowing conventional solid dosage forms. The tablets were prepared by wet granulation technique. Superdisintegrants such as sodium starch glycolate (SSG) and crospovidone were optimized as 5% on the basis of least disintegration time. Different...

Summary The superdisintegrants Primojel® (sodium starch glycolate) and Primellose® (croscarmellose sodium) are cross-linked and substituted polymers of glucose. The degree of cross-linking and substitution are important factors in determining the effectiveness of these materials as superdisintegrants. In the case of Primojel®, the selection of the type of starch is also a key factor, and in the case of Primellose®, particle size is important. This introduction to the chemistry and...

ABSTRACT: In the present study, novel co-processed superdisintegrants were developed by spray drying method using microcrystalline cellulose and mannitol in different ratios (1:1, 1:2 and 1:3) for use in the fast dissolving tablet formulations. The developed excipients were evaluated for angle of repose, Carr’s index and Hausner’s ratio in comparison with physical mixture of superdisintegrants. The angle of repose of the developed excipients was found to be < 30o, Carr’s index in the...

Abstract: The objective of this study was to design and evaluate Sitagliptin Phosphate immediate release (IR) 50 mg tablet using Response Surface Methodology for the managemant of Type-II diabetes mellitus. Response surface methodology (RSM) computations for this optimization study were performed employing Minitab 16. Different formulations of immediate release were prepared by applying 2 factor 2 level Central Composite Design (CCD) using Minitab 16 which gave 13 formulation for each layer....

Specific values of technological properties of excipients allow the establishment of numerical parameters to de ne and compare their functionality. This study investigates the functionality of Polyplasdones XL and XL10. Parameters studied included tablet disintegration pro les, compactibility pro les and powder ow. The results allowed the establishment of quantitative surrogate functionalities of technological performance, such as absolute number, and as a value relative to the known...

Disintegration performance was measured by analysing both water ingress and tablet swelling of pure microcrystalline cellulose (MCC) and in mixture with croscarmellose sodium using terahertz pulsed imaging (TPI). Tablets made from pure MCC with porosities of 10% and 15% showed similar swelling and transport kinetics... More
