Objective: The rationale of the current research work was to formulate and evaluate fast-dissolving tablets of doxazosin mesylate with minimum disintegration time and improved dissolution efficiency using solid dispersion method.Methods: Solid dispersions of doxazosin mesylate and polyethylene glycol 8000 in different ratios were prepared using the kneading method. The prepared solid dispersions were subjected to drug interaction and dissolution studies to select the effective solid dispersion for the formulation of fast-dissolving tablets. Fast dissolving tablets containing drug-polyethylene glycol 8000 solid dispersion (1:3) were prepared using various super-disintegrants such as crospovidone, croscarmellose sodium, mixture and coprocessed crospovidone and croscarmellose sodium in concentration range of 2% and 5% by direct compression technique. The prepared formulations (F1–F16) were evaluated for post compression parameters; hardness, thickness, friability, wetting time, disintegration time, and in–vitro drug release.Results: Drug doxazosin mesylate showed enhanced aqueous solubility of 13.3µg/ml in the presence of polyethylene glycol 8000. Differential scanning calorimetery and Fourier transform infrared spectroscopy studies confirmed no interaction between drug and polyethylene glycol 8000and, drug-polyethylene glycol 8000 solid dispersion showed cumulative drug release of 44.48% in 60 min. Formulated FDT of drug-polyethylene glycol 8000 solid dispersion, containing coprocessed mixture of crospovidone and croscarmellose sodium (5%) exhibited disintegration time of 14.5s with percentage cumulative release of 92.46% in 60 min.Conclusion: The work reasonably concludes that for the formulated doxazosin mesylate-fast dissolving tablets, disintegration time was effectively reduced by the presence of coprocessed mixture of crospovidone and croscarmellose sodium and dissolution efficiency was improved by preparation of solid dispersion with polyethylene glycol 8000.

Orally disintegrating tablets (ODT) disintegrate quickly with saliva when administered into the oral cavity and taken without water or chewed. ODT are easy to take for children and the elderly, who may experience difficultly in taking ordinary oral preparations such as tablets, capsules, and powders.  The ODT threes substantial benefits for the patient (or elder) who cannot swallow (Dysphagia), or who is not permitted water intake due to disease. The reason of the current research was to prepare taste masking oral disintegrating tablets of poorly soluble lornoxicam (LXM) by direct compression technique using Kyron T-114 (cation exchange resin) as a taste masking agent. With in various ratios the Drug-resin of 1:4 was established to present best taste masking. The superdisintegrants used in formulation are croscarmellose sodium and cross povidone. Among these croscarmellose sodium demonstrated superior drug release. The tablets were evaluated for friability, weight variation, wetting time, hardness, disintegration time and uniformity of content. Optimized formulations were evaluated for in vitro dissolution test. Amongst all the formulations F-6 was found to be most successful tablets prepared by this technique had disintegration time of 30sec and % CDR 94.78 within 30min. Hence, this advance can be utilized for taste masking of bitter pharmaceutical ingredients leading to superior patient compliance. Keywords: Oral disintegration tablets, Lornoxicam, Kyron T-114, Superdisintegrants, Direct Compression.

Purpose: To develop orodispersible tablets (ODTs) of fexofenadine hydrochloride using three different superdisintegrants in various ratios and to compare their disintegration properties.Methods: Direct compression technique was used for the preparation of ODTs. Mannitol and Avicel CE-15 (microcrystalline cellulose and guar gum) were used as direct compression diluents. The disintegration time of tablets using each polymer (superdisintegrant) was evaluated as well as othertablet properties including weight fluctuation, hardness, friability, wetting time and water absorption ratio.Results: Satisfactory values were obtained for all the evaluated parameters. As the polymer concentration increased, there was a decrease in disintegration time. A comparison of the three different polymers used revealed that CCM3 formulated with 12 % croscarmellose sodium and 14.66 % lactose had the least disintegration time of 32.33 ± 3.23 s. In vitro release studies showed that the maximum drug release of 94.38 ± 0.12 % in 25 min was obtained for ODT tablets containing croscarmellose sodium (CCM3).Conclusion: The orodispersible tablets had quick disintegrating property which was achieved using superdisintegrants. Thus, superdisintegrants improve the disintegration efficiency of orodispersible fexofenadine tablets at low concentrations, when compared to traditional disintegrants.

The objective of present study was to compare the disintegration efficiency of mucilage isolated from Plantago ovata with commonly used synthetic superdisintegrant, croscarmellose sodium in the formulation of orally disintegrating tablets. Effects of varying concentration of both superdisintegrants on disintegration time were studied. Orally disintegrating tablets of metoclopramide hydrochloride were prepared using selected superdisintegrants by direct compression technique. Prepared tablets were evaluated for weight variation, thickness, hardness, friability, disintegration time, wetting time, water absorption ratio and dissolution test. Swelling index was also investigated for comparing the swelling property of croscarmellose sodium with mucilage of Plantago ovata. Swelling index of mucilage isolated from Plantago ovata was found to be greater (94 ± 2.5% v/v) when compared with croscarmellose sodium (85 ± 1.5% v/v). The present study indicated that mucilage isolated from natural source proved to be more effective for their disintegrating property than the most commonly used synthetic superdisintegrant, croscarmellose sodium.

The objective of this investigation was to enhance the dissolution of glipizide using solid dispersions containing different superdisintegrants and to prepare rapidly disintegrating glipizide tablets with rapid absorption through the oral cavity by direct compression of the prepared solid dispersion. Primojel, Ac-Di-Sol and Kollidon CL were used as superdisintegrants. These excipients were used in different ratios and by using solvent evaporation method, rapidly disintegrating glipizide tablets were prepared by direct compression of the prepared solid dispersion, as well as, by camphor sublimation method aiming for more enhancing of tablet disintegration. Glipizide loaded with Kollidon CL showed the best dissolution properties compared to the other tested excipients. The physical properties of all the prepared GZ tablet formulations were found to be acceptable according to USP/NF2002. Kollidon CL containing formulations showed the most rapid disintegration time values reaching one second in tablets prepared by camphor sublimation method. The most effective formula in decreasing the blood glucose level was that containing glipizide loaded with Kollidon CL, with significant difference from the physically mixed ingredients or the pure GZ powder depending on Student’s T-test for area above the blood glucose level.

It is also intending to checkthe superiority in a combination of superdisintegrants and effervescent mixture than the use of superdisintegrants alone by a direct compressiontechnique. To fasten the onset of action and thereby enhancing the bioavailability of PLH in comparison to its conventional tablets.Methods: Standard calibration curve of PLH was obtained in pH 6.8 phosphate buffer by spectrophotometric method, drug-excipient compatibilitystudies were carried by Fourier transform infrared (FT-IR) studies. All the formulations were evaluated for pre and postcompression studies.Accelerated stability studies were carried out up to 6 months for the optimized formulation, EF3.Results and Discussion: Superdisintegrants used in the study are compatible with PLH. Pre- and post-compression parameters were within theacceptable limits for all formulations. In vitro dissolution kinetic studies indicate the release of PLH from ODT increases as the concentration ofsuperdisintegrants as well as the ratio of citric acid: NaHCO3 of effervescent mixture increases. Formulations with an effervescent mixture are havingrapid disintegration and dissolution rate when compared to the formulations with superdisintegrants alone. The order of superdisintegrants inenhancing the dissolution rate of PLH is crospovidone (CPV) > croscarmellose sodium (CCS) > sodium starch glycolate (SSG). Formulation, EF3 (10%CPV and 1:3, citric acid: NaHCO3 ratio, respectively) had the highest dissolution efficiency at 10 minutes (DE10=82.74%); the first order dissolutionrate constant (K1=0.141/minutes) with a regression coefficient (r2=0.974) and lesser time for 90% of drug release (t90=4 minutes), was considered asthe optimal ODT in this study. Formulation EF3, passed the test for stability.Conclusion: Hence, an effective PLH ODT was formulated by the direct compression technique with disintegration by combination of superdisintegrantsand effervescent mixture, will fasten the onset of action and enhances the bioavailability of PLH in comparison to its conventional tablets.Keywords: Propranolol HCl, Orally disintegrating tablet, Sodium starch glycolate, Croscarmellose sodium, Crospovidone, Direct compression, In vitrodissolution studies.

            Atorvastatin (ATR) is poorly soluble anti-hyperlipidemic drug; it belongs to the class II group according to the biopharmaceutical classification system (BCS) with low bioavailability due to its low solubility. Solid dispersions adsorbate is an effective technique for enhancing the solubility and dissolution of poorly soluble drugs.           The present study aims to enhance the solubility and dissolution rate of ATR using solid dispersion adsorption technique in comparison with ordinary solid dispersion. polyethylene glycol 4000 (PEG 4000), polyethylene glycol 6000 (PEG 6000), Poloxamer188 and Poloxamer 407were used as hydrophilic carriers and Aerosil 200, Aerosil 300 and magnesium aluminium silicate (MAS) as adsorbents.            All solid dispersion adsorbate (SDA) formulas  were prepared in ratios of 1:1:1  (drug: carrier: adsorbent) and evaluated for their water solubility, percentage yield, drug content,  , dissolution, crystal structure using  X-ray powder diffraction (XRD) and Differential Scanning Calorimetry (DSC)  studies and Fourier Transform Infrared Spectroscopy (FTIR) for determination the drug-carrier- adsorbate interaction.                The prepared (SDA) showed significant improvement of drug solubility in all prepared formula. Best result was obtained with formula SDA12(ATR :Poloxamer407 : MAS 1:1:1) that showed 8.07 and 5.38  fold increase in solubility compared to  solubility of pure ATR and  solid dispersion(SD4) (Atorvastatin: Poloxamer 407 1:1) respectively due to increased wettability and reduced crystallinity of the drug which leads to improve drug solubility  and  dissolution .

Objective: To synthesize, characterize and evaluate starch valerate as a superdisintegrant in the formulation of aceclofenac fast dissolving tablets by employing 23 factorial design. Methods: Starch valerate was synthesized and its physical and micromeritic properties were performed to evaluate it. The fast dissolving tablet of aceclofenac was prepared by employing starch valerate as a superdisintegrant in different proportions in each case by direct compression method using 23 factorial design for evaluation of tablet parameters like disintegration and dissolution efficiency in 5 min. Results: The starch valerate prepared was found to be fine, amorphous and free flowing. Starch valerate exhibited good swelling in water with swelling index (125.2%). The study of starch valerate was shown by fourier transform infrared spectra (FTIR). The drug content (200±5%), hardness (3.5–4 kg/sq. cm), and friability (<0.15%) has been effective with regard to all the formulated fast dissolving tablets employing starch valerate. The disintegration time of all the formulated tablets was found to be in the range of 14±0.04 to 25.7±0.02 sec. The optimized formulation F4 had the least disintegration time i.e., 12.8±0.02 sec. The wetting time of the tablets was found to be in the range of 76±0.21 to 217±0.17s. The In vitro wetting time was less (i.e., 28±0.02s) in optimized formulation F4. The water absorption ratio of the formulated tablets was found to be in the range of 46±0.12 to 100±0.27%. The percent drug dissolved in the optimized formulation F8 was found to be 99.93% in 5 min. Conclusion: Starch valerate, when combined with sodium starch glycolate, croscarmellose sodium, with aceclofenac, was found to be an effective super disintegrant which improved the dissolution efficiency and could therefore be used in the formulation of quick dissolving tablets to provide immediate release of the contained drug within 5 min.
