Objective: The present research work was to formulate matrix tablets of diclofenac sodium using mucilage extracted from Tinospora cordifolia as a novel binding agent. Also, a comparative study on binding properties of mucilage and carbopol were performed.Methods: Fresh stems of Tinospora cordifolia were collected and mucilage was extracted out using standard method. The isolated mucilage was characterised for physicochemical parameters. Formulation of diclofenac sodium tablets (f1-f6) was done by dry granulation method using 2%, 4%, 6%, 8% and 10% concentration of mucilage of Tinospora cardifolia as natural binder. Carbopol 2% was used as synthetic matrix forming agent. Microcrystalline cellulose was used as diluents, magnesium stearate and talc as lubricant. The formulated tablets were evaluated for parameters such as tablet thickness, hardness, weight variation, disintegration time, percent friability and in vitro drug release characteristics. The drug release mechanism was determined by fitting the release data into different kinetics models.Results: The results revealed that all the pre and post compression parameters of the formulated tablets (f1-f6) were in compliance with pharmacopoeial limits. In vitro drug release studies showed that formulation f6 containing maximum concentration of mucilage release the drug in a most controlled and sustained manner with maximum drug release of 63.6% in 15 h in comparison with f1(2% carbopol) giving 80% release and was found to be stable for 3 mo as indicated by stability studies. The mechanism of drug releases from formulation f1-f6 was found to be polymer disentanglement and erosion. Preformulation studies using FTIR study reveals that there is no incompatibility between the pure drug and mucilage of tinospora cardifolia used.Conclusion: Based on the experimental findings it can be concluded that Tinospora cordifolia mucilage can be used as a release retardant agent in the formulation of sustained release dosage forms.

Fast dissolving oral delivery systems are solid dosage forms, which disintegrate or dissolve within 1 minute in the mouth without drinking water or chewing. Mouth dissolving film (MDF) is a better alternate to oral disintegrating tablets due to its novelty, ease of use and the consequent patient compliance. The purpose of this work was to develop mouth dissolving oral films of palonosetron HCl, an antiemetic drug especially used in the prevention and treatment of chemotherapy-induced nausea and vomiting. In the present work, the films were prepared by using solvent casting method with various polymers HPMC E3, E5 & E15 as a film base synthetic polymer, propylene glycol as a plasticizer and maltodextrin and other polymers. Films were found to be satisfactory when evaluated for thickness, in vitro drug release, folding endurance, drug content and disintegration time. The surface pH of all the films was found to be neutral. The in vitro drug release of optimized formulation F29 was found to be 99.55 ± 6.3 7% in 7 min. The optimized formulation F29 also showed satisfactory surface pH, drug content (99.38 ± 0.08 %), disintegration time of 8 seconds and good stability. FTIR data revealed that no interaction takes place between the drug and polymers used in the optimized formulation. In vitro and in vivo evaluation of the films confirmed their potential as an innovative dosage form to improve delivery and quick onset of action of Palonosetron Hydrochloride. Therefore, the mouth dissolving film of palonosetron is potentially useful for the treatment of emesis disease where quick onset of action is desired, also improved patient compliance.

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.
