The intention of present research is to formulate and develop the meclizine hydrochloride fast dissolving tablets using sublimation method to enhance the dissolution rate. In this study an attempt was made to fasten the drug release from the oral tablets by incorporating the superdisintegrants and camphor as sublimating agent. The prepared fast dissolving tablets were subjected to precompression properties and characterized for hardness, weight variation, friability, wetting time, water absorption ratio, and disintegration time. From in vitro release studies, the formulation F9 exhibited fast release profile of about 98.61% in 30 min, and disintegration time 47 sec when compared with other formulations. The percent drug release in 30 min (Q30) and initial dissolution rate for formulation F9 was 98.61 ± 0.25%, 3.29%/min. These were very much higher compared to marketed tablets (65.43 ± 0.57%, 2.18%/min). The dissolution efficiency was found to be 63.37 and it is increased by 1.4-fold with F9 FDT tablets compared to marketed tablets. Differential scanning calorimetry and Fourier transform infrared spectroscopy studies revealed that there was no possibility of interactions. Thus the development of meclizine hydrochloride fast dissolving tablets by sublimation method is a suitable approach to improve the dissolution rate.

Objective: The purpose of this study was to enhance the dissolution pattern of the practically water-insoluble diuretic drug, furosemide through its formulation into liquisolid tablets.Methods: A mathematical model was used to formulate four liquisolid powder systems using polyethylene glycol 400 as a non-volatile water miscible liquid vehicle. The liquid loading factors of the vehicle were used to calculate the optimum quantities of carrier (Avicel PH 102) and coating materials (Aerosil 200) needed to prepare acceptably flowing and compactible powder mixtures and (R) ratio used was 25. The liquisolid tablets were evaluated for weight variation, percent friability, hardness, content uniformity, disintegration time and in vitro drug release profile. Drug and the prepared systems were characterized by fourier transform infrared spectroscopy (FTIR), differential scanning calorimetry (DSC) and powder x-ray diffraction (PXRD) studies.Results: The enhanced dissolution rate due to the increased wetting properties and the large available surface areas for dissolution were obtained in case of the liquisolid tablets. The selected optimal formulation (F2) of 50% drug concentration released 90% of its content during the first 10 min compared to 65% of DCT. FTIR studies revealed that there was no interaction between drug and polymers. DSC and PXRD indicated conversion of crystalline to amorphous form of furosemide. Conclusion: The dissolution rate of furosemide can be enhanced to a great extent by liquisolid technique.

Glibenclamide is a BCS Class II drug and poses a major problem during formulation development. In the present study, adsorption onto various carriers was used to enhance the solubility of glibenclamide. It was observed that solubility of glibenclamide was greatly enhanced by adsorbing onto mesoporous silica. The increase in solubility of poorly soluble drugs is often associated with the generation of supersaturation, which results in the risk of drug precipitation. HPMC E5 was used as precipitation inhibitor to maintain sink condition for a longer duration. A 32 full factorial design was adopted to optimize the ratio of glibenclamide (X1) and mesoporous silica as a carrier (X2) and the effect of different ratios was studied on percent yield, percent drug loading, and percent drug release. X-ray powder diffraction (XRPD) and Differential scanning calorimetry studies were performed to investigate any possible interaction in between glibenclamide and mesoporous silica. An optimum batch of drug adsorbate was used to prepare immediate-release tablets. The tablets prepared were evaluated for thickness, uniformity of weight, hardness, friability, in-vitro disintegration time, and in vitro drug release study.

The demands for fast dissolving tablets have received ever increasing day by day during the last decade. In the present projected study, the effect of natural Super disintegrants was compared with synthetic Super disintegrants and conventional Super disintegrants in the of fast dissolving tablet formulation of Meclofenamate Sodium. Meclofenamate sodium NSAID is used for the treatment of mild to moderate pain in various conditions like (e.g., dental pain, osteoarthritis) and to decrease pain and blood loss during menstrual periods. It is also used for other treatments like reducing pain, swelling, and joint stiffness caused with rheumatoid arthritis. In the present work 9 formulations of FDT (Fast dissolving tablet) of Meclofenamate Sodium were prepared by using Super disintegrants was evaluated and compiles with the official parameters and specifications. Various formulations were prepared using four different super disintegrants namely natural super disintegrant Banana Powder, sodium starch glycolate, crosscarmelose sodium with three concentrations (2%, 4%, 6%) by direct compression method. The blend was evaluated for pre-compression parameters like Angle of repose, bulk density, tapped density, and then tablet evaluated with various post-compression parameters like thickness, drug content, hardness, weight variation, wetting time, friability, disintegration time, dissolution time, drug release study. Formulation F2 showed the lowest disintegration time and in-vitro dissolution studies recorded that formulation F2 showed 98.55% drug release at the end of 3 minutes. The best formulations among these were also found to be stable and optimized formulations were subjected to the stability studies as per ICH guideline.

Present study efforts are focusing to develop the flurbiprofen fast dissolving tablets using sublimation method to enhance the dissolution rate. In this study an attempt was made to fasten the drug release from the oral tablets by incorporating the sublimating agents in the presence of crosspovidone as superdisintegrant and studied the effect on dissolution rate when compared to conventional tablets. In the present study, sublimated fast dissolving tablets were prepared by direct compression method. The prepared tablets were characterized for physical parameters and drug release behavior and the best formulation was subjected to pharmacokinetic studies. From in vitro drug release studies, the formulation F2 showed fast drug release of about 99.94±0.26% in 30 min, and disintegration time 34.42 ± 0.74 sec. The percent drug release in 15 min (Q15) and initial dissolution rate for formulation F2 was 91.46±1.42%, 6.10%/min. The dissolution efficiency was found to be 53.44 and it is increased by 4.5 fold with F2 sublimated tablets. From the pharmacokinetic evaluation, the conventional tablets producing peak plasma concentration (Cmax) was 9023.68±561.83 ng/ml at 3 h Tmax and F2 sublimated tablets showed Cmax 11126.71±123.56 ng/ml at 2 h Tmax. The area under the curve for the conventional and F2 tablets was 30968.42±541.52 and 42973.66±568.13 ng h/ml. Hence, the development of flurbiprofen fast dissolving tablets by sublimation method is a right way to enhance not only the dissolution rate but also the absorption rate.

The current research work involves preparation of fast dissolving tablets of Aceclofenac by direct compression method using different concentrations of Lepidium sativum mucilage as natural superdisintegrant. A two-factor three-level (32) factorial design is being used to optimize the formulation. Nine formulation batches (D1–D9) were prepared accordingly. Two factors as independent variables (X1-amount of β-cyclodextrin and X2-amount of Lepidium sativum mucilage) were taken with three levels (+1,0,-1). The levels of two factors were selected on the basis of preliminary experiments conducted and their effect on three dependent variables (disintegration time, wetting time, and in vitro drug release) was studied along with their % prediction error. All the active blends were evaluated for postcompression parameters (angle of repose, Carr’s index, Hausner ratio, etc.) and the tablets were evaluated for postcompression parameters (weight variation, hardness, and friability, wetting time, disintegration time, water absorption ratio, and in vitro drug release studies). The optimum batch was further used for SEM and stability studies. Formulation D5 was selected by the Design-Expert software which exhibited DT (15.5 sec), WT (18.94 sec), and in vitro drug release (100%) within 15 minutes.

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.

Present work focused on thiolation for enhancing the mucoadhesive potential of Gum kondagogu (GK). Thiolation of GK was done by esterification process with 80 % thioglycolic acid in presence of 7N HCl. Thiolated Gum kondagogu (ThioGK) was determined to possess 1.59 ±0.04 mmol of thiol groups/g of the polymer by Ellman’s method. ThioGK was characterized by FTIR, NMR, DSC, XRD, and FE-SEM. The tablets were prepared by direct compression using 75 mg of ThioGK and GK. Tablets containing ThioGK (F1) and GK (F2) were subjected to evaluation of weight variation, hardness and friability and show enhanced disintegration time, swelling behavior, drug release and mucoadhesion. In vitro drug release of batch F1 exhibits complete release of drug in 24 hr with zero order release kinetics. Comparative mucoadhesive strength was studied using chicken ileum by texture analyzer and revealed higher mucoadhesion of tablet containing ThioGK. From the above study, ThioGK was suitability exploited as mucoadhesive sustained release matrix tablet.

Fast Disintegrating Tablet

Objective: The aim of the present investigation was to design and evaluate orally disintegrating tablet (ODT) of Ibuprofen, a NSAID drug used for the treatment of arthritis with a view to improve its oral bioavailability. The focus of the current study was to develop ODT of Ibuprofen using super disintegrants for ease of administration and its physicochemical characterization.Methods: Tablets were made from blends by direct compression method. All the ingredients were passed through mesh no. 80. All the ingredients were co-ground in a pestle motor. The resulting blend was lubricated with magnesium stearate and compressed into tablets using the Cadmach single punch (round shaped, 8 mm thick) machine.Results: Physicals parameters of the prepared tablets like Hardness, Weight variation, Friability, thickness, drug content etc. found within the limits. The disintegration time of prepared ODTs was in the range of 45 to 55 seconds. In vitro dispersion time was found to be 22 to 52 seconds which may be attributed to faster uptake of water due to the porous structure formed by super disintegrants. Short disintegration and faster release of ibuprofen were observed with Cross carmellose sodium as compared to sodium starch glycollate.Conclusion: It is concluded that F3 offered the relatively rapid release of Ibuprofen when compared with other formulations. The increase in the concentrations of super disintegrants may lead to increase in the drug release. The formulation prepared with cross carmellose sodium was offered the relatively rapid release of Ibuprofen when compared with other concentrations of both the super disintegrant.
