Chewable Tablets

In the modern era, chewable tablets are preferred over conventional dosage forms by pediatric, geriatric and bedridden patients due to difficulty in swallowing, lesser amount of water for swallowing medications as well as unable to tolerate the bitter taste of certain drugs. Chewable tablets of Desloratadine (DS) were formulated by aqueous and non-aqueous granulation method using water paste and Isopropyl alcohol (IPA) as a wetting agents respectively. Desloratadine is used to treat the symptoms of allergy such as sneezing, watery eyes. In the recent research, we have formulated eight trials by various concentrations of excipients. For instance; lactose, talcum, magnesium stearate, blue color, flavor, aspartame, mannitol, avicel 101 and polyvenylpyrollidine (PVP). Pre-compression and post compression parameters (thickness, hardness, friability weight variation and drug content) of the formulations were evaluated. B3 was our optimum dosage form because its Hausner’s ratio, compressibility index, bulk density, tap density, angle of repose have optimum values i.e. 1.01, 5.1%, 0.66(g/cc), 0.69(g/cc), 26.1º respectively and post-compression i.e. thickness, hardness, friability weight variation and drug content have values, 2.9mm, 3.9(kg/cm²), 0.6%, 99.5% respectively. Tablets prepared by wet granulation technique showed reasonable release profile i.e. 100% within the required time i.e. 2 hours.  Moreover, organoleptic evaluation of all formulations were performed. Keywords: Desloratadine, chewable, magnesium stearate, aspartame, compressibility, granulation.

Promethazine.HCl is a potent anti-emetic. The central antimuscarinic actions of antihistamines are probably responsible for their anti-emetic effects. Promethazine is also believed to inhibit the medullary chemoreceptor trigger zone, and antagonize apomorphine -induced vomiting. Fast dissolving tablets of Promethazine.HCl were prepared using five superdisintegrants viz; sodium starch glycolate, crospovidone, croscarmellose, L-HPC and pregelatinised starch. The precompression blend was tested for angle of repose, bulk density, tapped density, compressibility index and Hausner’s ratio. The tablets were evaluated for weight variation, hardness, friability, disintegration time (1 min), dissolution rate, content uniformity, and were found to be within standard limit. It was concluded that the fast dissolving tablets with proper hardness, rapidly disintegrating with enhanced dissolution can be made using selected superdisintegrants. Among the different formulations of Promethazine.HCl was prepared and studied and the formulation S2 containing crospovidone, mannitol and microcrystalline cellulose combination was found to be the fast dissolving formulation. In the present study an attempt has been made to prepare fast dissolving tablets of Promethazine.HCl, by using different superdisintegrants with enhanced disintegration and dissolution rate.

The objective of this study was to develop a sustained release matrix tablet of aceclofenac usinghydroxypropyl methylcellulose (HPMC K15M and HPMC K100M CR) in various proportions as release controllingfactor by direct compression method. The powders for tableting were evaluated for angle of repose, loose bulkdensity, tapped bulk density, compressibility index, total porosity and drug content etc. The tablets were subjected tothickness, weight variation test, drug content, hardness, friability and in vitro release studies. The in vitro dissolutionstudy was carried out for 24 hours using United States Pharmacopoeia (USP) 22 paddle-type dissolution apparatus inphosphate buffer (pH 7.4). The granules showed satisfactory flow properties, compressibility index and drug contentetc. All the tablets complied with pharmacopoeial specifications. The results of dissolution studies indicated that theformulations F-2 and F-3 could extend the drug release up to 24 hours. By comparing the dissolution profiles with themarketed product, it revealed that the formulations exhibited similar drug release profile. From this study, a decreasein release kinetics of the drug was observed when the polymer concentration was increased. Kinetic modeling of invitro dissolution profiles revealed the drug release mechanism ranges from diffusion controlled or Fickian transport toanomalous type or non-Fickian transport, which was only dependent on the type and amount of polymer used. Thedrug release followed both diffusion and erosion mechanism in all cases. The drug release from these formulationswas satisfactory after 3 months storage in 40°C and 75% RH. Besides, this study explored the optimum concentrationand effect of polymer(s) on acelofenac release pattern from the tablet matrix for 24 hour period.Key words: Aceclofenac; sustained release; hydrophillic matrix; HPMC; direct compression.DOI: 10.3329/dujps.v8i1.5332Dhaka Univ.

Objective: To investigate the possible individual and joined influences that binding solution concentration, drying temperature and drying duration might have on the physiochemical attributes of granules and tablets using norfloxacin as a model drug. Methods: According to implemented 23 central composite designs, each of the investigated variables were examined at 5 different levels through different 16 formulation runs. For each formulation, obtained granules were qualified for their bulk density, tap density, Hausner ratio, percent of fine and drug content properties whereas the respective tablets were evaluated for their weight variation, drug content, friability, hardness, disintegration, and drug dissolution attributes. Results: Indicated that concentration of binder solution, as compared to drying temperature and drying duration, measured more profound influences on granules' tap density, Hausner ratio, % fine and drug content either through its individual linear and quadratic effects or through its joint effect with drying durations (p<0.05 at 95% CI for all influences). Whilst tablets' friability appeared to be noticeably influenced by the three investigated variables (P ranged 0.001-0.017 at 95% CI), tablets' hardness and disintegration were found to be considerably affected only by binder solution concentration (p = 0.001 and 0.082 at 95% CI, respectively). Moreover, none of the investigated variables has measured a significant influence on tablets' drug content or drug dissolution properties. Conclusion: The study concluded that quadratic and joint influences of variables on attributes of granule and tablet formulations shouldn't be overlooked and better to be considered in the screening design.
