The current scenario emphasize on oral administration. The main disadvantage in oral administration was difficulty in swallowing for pediatric and geriatric patients. To solve this problem in oral drug delivery system, the formulation of fast dissolving systems found to be the best alternatives.  The present investigation involves in the evaluation of starch succinate as a superdintegrant in the formulation of fast dissolving tablets of poorly soluble drugs employing 23factorial design. Starch succinate was synthesized by esterification process. The synthesized starch succinate was subjected to physical and micromeritic evaluation. All fast dissolving tablets were evaluated for drug content, hardness, friability, disintegration time and other dissolution characteristics like percent dissolved in 5 min (PD5), dissolution efficiency in 5 min (DE5%) and first order rate constant(K1). The starch succinate prepared was found to be fine, free flowing crystalline powder. Starch succinate exhibited good swelling in water. Fourier transform infrared spectra (FTIR) and Differential scanning calorimetry (DSC) study indicated the absence of interaction between ibuprofen and starch succinate. All the fast dissolving tablets formulated employing starch succinate were of good quality with regard to drug content (200±2%), hardness (3.6–4.0 kg/sq. cm), and friability (0.12-0.15%). The optimised formulation F8 has the least disintegration time i.e., 15±0. 02s. The in–vitro wetting time was less (i.e., 15s) in optimized formulation F8. The water absorption ratio of the formulated tablets was found to be in the range of 31.4±0.01 to 68.0±0.04%. The cumulative drug dissolved in the optimized formulation F8 was found to be 99.81± 0.22% in 5 min. Starch succinate was found to be a superdisintegrant which enhanced the dissolution efficiency with the ibuprofen and hence it could be used in the formulation of fast dissolving tablets to bring immediate release of the contained drug within 5 minutes. Keywords: Fast dissolving, Superdisintegrant, Starch succinate, Dissolution efficiency.

Objective: The objective of the present research was to prepare starch phthalate (a novel superdisintegrant) and to optimize and formulate acyclovir fast dissolving tablets employing 23 factorial design using starch phthalate as superdisintegrant. Materials and Methods: Drug excipient compatibility studies such as Fourier-transform infrared spectroscopy, differential scanning calorimetry, and thin-layer chromatography were carried out to check the drug interaction between acyclovir and starch phthalate. The direct compression method was used for tablet preparation. Prepared tablets were then evaluated for hardness, friability, drug content, disintegration time, water absorption, and wetting time, in vitro dissolution studies. Response surface plots and contour plots were also plotted to know the main effects and interaction effects of independent variables (starch phthalate [A], croscarmellose sodium [B], and crospovidone [C] on dependent variables [disintegration time and drug dissolution efficiency in 1 min]) and stability studies were also done. Results: Tablets of all formulations were of good quality concerning drug content (100±5%), hardness (3.6–4.0 kg/cm2), and friability (<0.16%). In all formulations, formulation F8 found to be optimized formulation with least disintegration time 9±3 s, less wetting time 10±0.17 s, and enhanced dissolution rate in 1 min, i.e., 99.92±0.11 as compared to other formulation. Conclusion: From the research, it was concluded that on combination with crospovidone (5%) and croscarmellose sodium (5%), starch phthalate (10%) enhanced the dissolution efficiency of the drug. Hence, starch phthalate can be used as a novel disintegrant in the manufacturing of fast dissolving tablets.

Objective: The study describes the development of chitosan-based (AMPS-co-AA) semi-IPN hydrogels using free radical polymerization technique. Methods: The resulting hydrogels were characterized using Fourier Transform Infrared Spectroscopy (FTIR), Thermogravimetric Analysis (TGA), Differential Scanning Calorimetry (DSC), X-Ray diffraction (XRD), and Scanning Electron Microscopy (SEM). The successful crosslinking of chitosan, 2- Acrylamido-2-Methylpropane Sulfonic Acid (AMPS), and Acrylic Acid (AA) was confirmed by FT IR. Unloaded and drug-loaded hydrogels exhibited higher thermal stability after crosslinking compared to the individual components. XRD confirmed the decrease in crystallinity after hydrogel formation and molecular dispersion of Oxaliplatin (OXP) in the polymeric network. SEM showed rough, vague and nebulous surface resulting from crosslinking and loading of OXP. Results: The experimental results revealed that swelling and drug release were influenced by the pH of the medium being low at acidic pH and higher at basic pH. Increasing the concentration of chitosan and AA enhanced the swelling, drug loading and drug release while AMPS was found to act inversely. Conclusion: It was confirmed that the hydrogels were degraded more by specific enzyme lysozyme as compared to the non-specific enzyme collagenase. In-vitro cytotoxicity suggested that the unloaded hydrogels were non-cytotoxic while crude drug and drug-loaded hydrogel exhibited dose-dependent cytotoxicity against HCT-116 and MCF-7. Results of acute oral toxicity on rabbits demonstrated that the hydrogels are non-toxic up to 3900 mg/kg after oral administration, as no toxicity or histopathological changes were observed in comparison to control rabbits. These pH-sensitive hydrogels appear to provide an ideal basis as a safe carrier for oral drug delivery.

The present work concerned with formulation and evaluation of fast disintegrating tablet of Topiramate by using natural superdisintegrants like Trigonellafoenum graceum (fenugreek) powder, Plantago ovata powder, dehydrated banana powder, soy polysaccharide, linseed powder. Topiramate is an antiepileptic drug and also used in migraine. Preformulation studies like solubility, melting point were studied. Five formulations were prepared using different natural superdisintegrant with same concentrations by using direct compression method. All the formulations were evaluated for precompression parameters and all the parameters were found to be within the pharmacopoeial limits. Post compression parameters like hardness of the tablet, thickness of the tablet, friability test, weight variation, disintegration test, in-vitro dissolution test, drug content were performed. The formulation F-5 containing Trigonellafoenum-graceum (fenugreek) powder shown disintegration time of 12sec. Rapid disintegration of the Trigonellafoenum-graceum due to its rapid water absorbency swells in water to the extent of 200–300% disintegrates rapidly for quick and complete disintegration of the tablet. An accelerated stability study on optimized formulation was performed and it was found to be stable. It can be concluded that Trigonellafoenum-graceum (fenugreek) powder as Superdisintegrant showed better release than soy polysaccharide, plantago ovata powder, dehydrated banana powder and linseed powder.
