Objective: The main objective of this study is comparative study of natural and synthetic superdisintegrants in orodispersible Metformin tablet by using direct compression method and wet granulation method. Method: Orodispersible Metformin tablet were prepared by wet granulation method and direct compression method by using different synthetic and natural superdisintegrants. Orodispersible tablets (ODTs) have received more interest in the pharmaceutical industry for their easy to use and self medication. ODTs overcome the problem of dysphagia (difficulty in swallowing) in the all group age of patients and advantage particularly for the paediatric and geriatric patients. Metformin hydrochloride (Hcl) is an orally administered antihyperglycemic agent, used in the management of non-insulin dependent (type-2) diabetes mellitus. Metformin orodispersible tablet is prepared by using two methods i.e. direct compression method and wet granulation method. Both methods are applied to prepare Orodispersible Metformin tablet. Orodispersible tablet of Metformin was prepared by using superdisintegrants from both natural and synthetic origin. In natural superdisintegrants we used the mucilage of Fenugreek and Lepidium sativum. In synthetic superdisintegrants we used crospovidone and sodium starch glycolate. Conclusion: In direct compression and wet granulation method final blend and granules were evaluated the flow properties like bulk density, tapped density, compressibility index, hausner’s ratio and angle of repose. The values of precompression parameter evaluated were found to be within the prescribed limit and indicated good flow properties. The data obtained from the post compression methods was studied. Other parameters such as wetting time, water absorption ratio were also evaluated. The formulation (F5) containing 10% crospovidone prepared by wet granulation method was found the optimize formulation.

Minitablets can be used either single or multiple unit sustained release dosage form. The objectives of this study were to prepare and evaluate the prolonged action, bioadhesive and slowly dissolving minitablets. The minitablets (Ø 2.5 mm, 7 mg) were prepared by direct compression method using 75%w/w of various hydrophilic polymers: hydroxypropylcellulose (HPC), hydroxypropyl methylcellulose (HPMC), carboxy methylcellulose (CMC), pectin (PT) and chitosan (CS). Spray dried lactose was used as diluent. Prior to compression, the angle of repose, bulk-tab density and %compressibility of each mixed powder were evaluated. The rate of hydration and erosion of the obtained minitablets were carried out in phosphate buffer (pH 7.4). The powder blends containing HPC, CMC or HPMC showed satisfactory flow properties and compressibility. Accordingly, the prepared matrix tablets of HPC, CMC and HPMC showed good physical properties such as hardness, while those of CS and PT showed poor properties. The degree of swelling were ranked as CS>CMC>PT>HPC>HPMC, while the erosion were ranked as CMC≈HPMC≈PT > HPC≈CS. Adhesion time of these minitablets on isolated pig intestine was >30 min for CMC, PT and CS tablets while HPC and HPMC tablets exhibited weaker bioadhesion. In conclusion, among tested polymers, CS, PT and CMC were appropriate for prolonged action, bioadhesive and slowly dissolving minitablets.

In the present study sustained release diclofenac sodium matrix tablets were prepared using Kollidon SR polymer. Hydroxypropyl methylcellulose (HPMC 15 cps) and poly ethylene glycol (PEG-600) polymers respectively were used in formulating tablets prepared by direct compression and wet granulation methods. The polymers were used to explore the release pattern of the drug into the dissolution media. The tablets were also prepared in various shapes (caplet oval, round oval and flat oval). A comparatively higher release rate of drug was obtained from the polymer HPMC 15 cps at 10% concentration for directly compressed matrix tablet than those containing 20% of HPMC after a definite period of time. In wet granulation process, 10% PEG-600 containing tablets showed a better release than those containing 20% PEG. The drug release was also found to be sustained in case of wet granulation method than that of the direct compression method. Again the caplet shaped tablets in case of direct compression method showed better release rate of drug than those of the round oval and flat oval shaped tablets. Thus the result of this study shows that the proper selection of the percentage of polymer and the suitable shape of tablet and proper manufacturing method can provide a greater opportunity in designing sustained release dosage forms.

The aim of this work was to improve fluconazole flowability by wet granulation and to study the effect of granulation on drug dissolution from tablets and capsules. Fluconazole was submitted to a process of wet granulation in a high-speed granulator using Plasdone® K29/32 or K90. Flow properties of granules and dissolution profiles for tablets and capsules produced with them were determined. Fluconazole granules demonstrated better flowability, calculated by angle of repose and compressibility index data, compared with powder. Additionally, it was observed that the granulation process improved the dissolution efficiency (ED) of fluconazole from tablets and capsules, which could also suggest an increase in bioavailability. Higher dissolution efficiencies were achieved with Plasdone® K29/32.

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.
