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.

The objective of the present investigation was to identify a suitable raft forming agent and to develop raft forming stavudine matrix tablets using different rate controlling natural, semi-synthetic and synthetic polymers to achieve prolonged gastric residence time, leading to an increase in drug bioavailability and patient compliance. Various raft forming agents were used in preliminary screening. Raft forming floating tablets were developed using pullulan gum as natural rate controlling polymer, and directly compressible grades of hydroxypropyl methylcellulose (Benecel K4M DC) as semi synthetic, and Carbopol 71G as synthetic rate controlling polymers respectively and optimum concentrations of sodium-bicarbonate as gas generating agent to generate optimum buoyancy by direct compression method. Raft forming tablets were evaluated for weight variation, thickness, hardness, friability, drug content, in vitro drug release, floating buoyancy and raft strength. Drug-excipients compatibility study showed no interaction between drug and excipients. Raft forming tablets showed satisfactory results when evaluated for weight variation, thickness, hardness, friability, drug content, and raft strength. The optimized formulation was selected based on physicochemical characteristics and in vitro drug dissolution characteristics. Further, the optimized formulation was evaluated for in vivo radiographic studies by incorporating BaSO4 as radio opaque substance. Optimized formulation showed controlled and prolonged drug release profiles while floating and raft formation over the dissolution medium. Diffusion followed by erosion with raft forming drug release mechanism was observed for the formulation, indicating that dissolution media diffusion and polymer erosion played an essential role in drug release. In vivo radiographic studies revealed that the raft forming formulations remained in the stomach for 240 30 min in rabbits and indicated that gastric retention time was increased by the floating and raft forming principle, which was considered and desirable for absorption window drugs.

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.

The aim of this study was to design orally disintegrating tablet (ODT) of Lamotrigine. It is an Antiepileptic drug which is widely used in epilepsy. It is also used in simple and complex partial seizures and secondary generalized tonic-clonic seizures. It is poorly water soluble drug (0.46 mg/ml). Thus, an attempt was made to enhance the water solubility by complexation with β-cyclodextrin (1:1 molar ratios). The orally disintegrating tablet of lamotrigine was prepared by direct compression method using different concentration of superdisintegrants such as Sodium starch glycollate, croscarmellose sodium by sublimating agent such as camphor. The formulations were evaluated for weight variation, hardness, friability, drug content, wetting time, in vitro disintegration time and in vitro dissolution studies. The prepared tablets were characterized by Fourier transform infrared spectroscopy and differential scanning calorimetry. The disintegration time for the complexed tablets prepared by different concentration of superdisintegrants was found to be in range of 32.54 ± 0.50 to 55.12 ± 0.57 sec and wetting time of the formulations was found to be in range of 28.47 ± 0.67 to 52.19 ± 0.72 sec. All the formulation showed almost 100 percent of drug release within 15 min. Among all the formulation F6 and F7 prepared with 18% croscarmellose sodium and camphor shows faster drug release, respectively 10 min, F6 gives good result for disintegration time, drug release, wetting time and friability. Further formulations were subjected to stability testing for 30 days at temperature of 40 ± 5 ºC/75 ± 5 %RH. Tablets showed no appreciable changes with respect to physical appearance, drug content, disintegration time and dissolution profiles. Results were statistically analyzed by one-way ANOVA at a p < 0.05. It was found that, the data at any point of time are significant at p < 0.05.

In the present work, orodissolving tablets of Efavirenz were prepared by direct compression method with a view to enhance patient compliance. A 23 full factorial design was applied to investigate the combined effect of three formulation variables. Amount of crospovidone, croscarmellose sodium and sodium starch glycolate were used as superdisintegrant material along with direct compressible mannitol to enhance mouth feel. The prepared batches of tablets were evaluated for hardness, friability, weight variation, disintegration time, wetting time, drug content and in-vitro dissolution studies. Based on wetting time, disintegration time, the formulation containing crospovidone (5% w/v), carscarmellose sodium (5% w/v) and sodium starch glycolate (8% w/v) was found to be promising and tested for in-vitro drug release pattern (in 0.1 N HCl), short term stability and drug- superdisintegrants interaction. Surface response plots are presented to graphically represent the effect of independent variables (conc. of superdisintegrants) on the in-vitro dissolution time. The validity of the generated mathematical model was tested by preparing extra-design check point formulation. The formulation showed nearly faster drug release compared to the conventional commercial tablet formulation. Stability studies on the optimized formulation indicated that there was no significant change found in physical appearance, hardness, disintegration time, drug content and in-vitro drug release.
