This study is aimed at evaluating the binding effect of Acacia etbaica gum in granule and tablet formulations using paracetamol as a model drug. Some physicochemical properties of the purified gum such as pH, the presence of tannin and dextrin, solubility, viscosity, loss on drying, total ash value, water solubility index, swelling power, moisture sorption, and powder flow properties were investigated. Paracetamol granules were prepared using wet granulation method at 2%, 4%, 6%, and 8% w / w of the Acacia etbaica gum and compared with granules prepared with reference binders (PVP K-30 and Acacia BP) in similar concentrations. The granules were characterized for bulk and tapped densities, compressibility index and Hausner ratio, angle of repose, flow rate, and friability. Finally, the prepared granules were compressed into tablets and evaluated for different tablet characteristics: weight uniformity, thickness, diameter, crushing strength, tensile strength, friability, disintegration time, and in vitro release profile. The physicochemical characterization revealed that tannins and dextrin are absent in the gum, and the gum has acidic pH. Both the moisture content and total ash values were within the official limits. Furthermore, the gum was found to be soluble in cold and hot water but insoluble in organic solvent and exhibited a shear thickening viscosity profile and excellent flow properties with excellent compressibility. The granules prepared with the gum of Acacia etbaica and reference binders showed good particle size distribution and excellent flow and compressibility properties. All the prepared tablets passed pharmacopeial specifications with respect to their uniformity of weight, thickness, and disintegration time. Tablets formulated with Acacia etbaica gum and acacia BP meet the compendial specification for friability at binder concentrations more than 2%. Drug release properties of all the batches formulated with Acacia etbaica, PVP, and acacia BP complied with the pharmacopeial specification. It can be concluded that the gum of Acacia etbaica could be explored as an alternative excipient for its binder effect in granule and tablet formulations.

Background: Tablets must be able to release the active drug in the gastrointestinal tract for absorption. The release profile of solid pharmaceutical dosage formulations can be quantified by assessing the disintegration and dissolution times tests. Binders are adhesives either from sugar or polymeric material that are added to tablet formulations to provide the cohesiveness required for the bonding together of the granules under compaction to form tablets.Objective: The objective of the study was to formulate and assess ibuprofen tablets using different concentrations of binders (Acacia and Gelatin).Methods: The granules were prepared using wet granulation method and analysed for flow properties based on USP/NF protocols. After granule compression, the tablets release profiles were thereafter assessed via the tablet dissolution and disintegration tests.Results: Weight variation, thickness and diameter were within the acceptable values for all batches indicative of a uniform flow. Batches with binder concentrations of 10 % and 20 % failed disintegration test due to a disintegration time above 15 min while the release rate for batches 1 and 4 was about 88 % in 60 min as against the other batches whose release rate was less than 50 % in 60 min as a result of increasing their binder concentrations.Conclusion: The study concluded that increasing the concentration of acacia and gelatin above 5% led to a decrease in percentage of drug released and an increase in disintegration time above 30 mins because 5% batches gave the best release profiles.

The present work is aimed to formulate the tablets containing fenugreek extract as drug by wet granulation method. Further the effect of Sodium Starch Glycolate as super disintegrant on disintegration and drug release was studied. Fenugreek extract contains mucilage which retards the disintegration of tablets and hence shows slower drug release. Hence in order to improve disintegration and thereby in vitro drug release, Sodium Starch Glycolate was used as super disintegrant. Tablet formulations were prepared without the SSG (Conventional-F1) and also with sodium starch glycolate (F2-F4) by wet granulation method. Assessment of flow properties of granules, physicochemical characterization of tablet formulations was carried out. Fenugreek is widely used for its antidiabetic activity which is attributed to mainly to the presence of an alkaloid Trigonelline. Hence in vitro release study of trigonelline was carried out which showed that the percentage release from F1 and F2 was found to be 58.12±4.49 and 99.08±0.01 respectively after 6 hrs. This study concludes that tablet formulation of fenugreek seed extracts with super disintegrants will be more desirable, advantageous and therapeutically more beneficial than incorporating the direct plant materials for the treatment of diabetes for faster onset of action.

Ibuprofen is one of the common NSAIDs having poor water solubility, low dissolution, weak flow properties and reduced compressibility. These downsides of ibuprofen crystal upraise crucial challenges during development of a dosage form. The aim of this present work was to modify the physical form of ibuprofen by changing micromeritic properties. Seven different formulations of ibuprofen agglomerates such as F-1, F-2, F-3, F-4, F-5, F-6 and F-7 were prepared to convert the needle shaped ibuprofen crystals into agglomerates so that the desired micromeritic properties can be achieved. In this study, agglomerates of ibuprofen were prepared by Quasi emulsion solvent diffusion (QESD) method in association with two surfactants (sodium lauryl sulphateand Tween 80) at three different concentrations for each. The micromeritic properties of the prepared agglomerates were evaluated for bulk density, tapped density, Carr’s index, Hausner’s ratio, angle of repose along with the release behavior of agglomerates. From dissolution study, it was observed that the release of drug was directly proportional to the surfactant concentration. Here, it was also revealed that there was no interaction among ibuprofen and other excipients as evident from DSC and FTIR studies.Bangladesh Pharmaceutical Journal 20(1): 90-98, 2017
