Purpose : The aim of this study was to evaluate the influence of the geometric shape on the dissolution rate of the domperidone, a drug model for immediate release dosage form. In this regard, a lack of sufficient information about the effective dissolution rate of the drugs regarding their shapes has made this issue an interesting subject for researchers. Methods: For this purpose, three tablet shapes, namely flat and biconvex both in a round and oblong shapes, with different four sizes were modelled for the preparation of domperidone tablet. In vitro dissolution test was accomplished using a USP dissolution apparatus II. The drug dissolution rate was assessed by calculating various dissolution parameters; e.g., dissolution efficiency (DE), mean dissolution rate (MDR), mean dissolution time (MDT), and difference and similarity factors (f1 and f2 ). Results: Regarding the disintegration time, the larger tablets showed a faster disintegration time. When the size of the tablets was smaller, the amount of released drug was significantly decreased. In addition, #9 tablets with a flat or biconvex geometry had obvious effects on the DE values. Generally, biconvex tablets had higher DE percentage than the flat tablets. Conclusion: Noticeable differences in dissolution parameters by considering the different geometric shapes play an important role in the drug release kinetics which makes a significant effect on quick onset of action in oral administration.

The aim of the present study was to develop and optimize immediate release tablets using hydrochlorothiazide (HCTZ) as a model drug candidate applying Design of Experiments (DoE) approach. Immediate release tablets were prepared using corn starch as a disintegrant and Polysorbate 80 as a solubilizer. Risk assessment was carried out with subsequent application of 22 factorial design in duplicate for evaluating the interactions and effects of the design factors on critical quality attributes. The design space was obtained by applying DOE and multivariate analysis, so as to ensure desired disintegration time (DT) and in vitro drug dissolution. Immediate release tablets were evaluated for hardness, thickness, friability and in vitro drug dissolution. Optimized formulation obtained from the design space exhibits DT of around 38s, while dissolution time, T96% (time required to release 96% of the drug) was about 45 min. The independent variables have a significant effect over the dependent responses, which can be deduced from Contour plots and surface response graphs. The predicted values matched well with the experimental values and the result demonstrated the feasibility of the design model in the development and optimization of HCTZ immediate release tablets.

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.

Among the different type of route of administration oral route for drug administration is most common route in which Orodispersible tablet is preferred for the patient which are unconscious, week or for immediate control. The tablet gets dispersed in mouth cavity without water, present study deals with formulation of Naproxen sodium mouth dissolving tablets using super disintegrants. Naproxen sodium is analgesic and NSAID, used for the treatment of pain and inflammation caused by different condition such as osteoarthritis, rheumatoid arthritis and menstrual cramps. However gastric discomfort caused by naproxen sodium result in poor patient compliance associated with it conventional doses form but now days Naproxen sodium MDTs produces rapid onset of action and minimise gastric discomfort associated with it. Thus improves patient compliance, enhance bioavailability and reduces the dose of drug. MDTs are formulated by direct compression method using super disintegrants in different proportion. The powder blend is subjected to pre-compression evaluation parameters like bulk density, true density, and tapped density and angle of repose. Formulations are evaluated for weight variation, hardness, wetting time, water absorption time, disintegration time. And in vitro dissolution studies and all formulations complies Pharmacopoeias standards. The tablets are evaluated and result compared for all five formulation the most efficacious super disintegrants for MTDs of Naproxen sodium as suggested by the dispersion time, disintegration time and drug dissolution profiles. Keywords: - MDT, Naproxen Sodium, crosscarmellose Sodium, Sodium starch glycolate, Cross-povidone.

The rationale of this investigation is to design an immediate release oral dosage of Sumatriptan succinate by using microcrystalline cellulose as filler, camphor and menthol as subliming agents by direct compression method .The basic objective of this dissertation is to develop an orodispersible tablet of sumatriptan succinate used in anti-migraine with an aim of reduces the lag time and providing faster onset of action to relief the acute migraine effect immediately. Disintegrates and disperses in oral cavity within 30 seconds without the need of drinking water. Has pleasant mouth feel and there is no after taste or grittiness. Successfully discriminates the ability of three superdisintegrants to promote drug dissolution and proposes a model formulation for disintegrants performance testing and quality control purposes. The formulation F6 containing 8% of CCS and 10% of menthol showed disintegration time of 18seconds after drying. Menthol as subliming agent was found to be most effective of all other subliming agents as it had showed drastic effect on the drug release. Keywords: Sumatriptan succinate, sublimation, menthol, anti-migraine
