The objective of the study was to investigate the suitability of the Plantago ovata (PO) husk as a pharmaceutical excipient. Various phytoconstituents of the husk were determined according to the standard test procedures. The Plantago ovata husk was evaluated for various pharmaceutical parameters related to flow, swelling index, and compressibility index. Orodispersible tablets (ODTs) were prepared, containing different concentrations (2.5, 3, 5, 7.5, 10, and 15% w / w ) of the Plantago ovata husk. Before compression, all the formulations were evaluated for their flow. Compressed ODTs were evaluated for physical characteristics (physical appearance, weight and weight variation, thickness, and moisture content), mechanical strength (crushing strength, specific crushing strength, tensile strength, and friability), disintegration behavior (disintegration time and oral disintegration time), drug content, and in vitro drug release. Phytochemical evaluation of the Plantago ovata husk confirmed the presence of various phytoconstituents like alkaloids, tannins, glycosides, saponins, flavonoids, and phenols. SEM photograph of the Plantago ovata husk showed that it has a fibrous structure, with a porous and rough surface. The Plantago ovata husk had a high swelling index (380%) which decreased by pulverization (310%). Precompression evaluation of the powder blend for all the formulations of ODTs showed good flow properties, indicating that the Plantago ovata husk improved the rheological characteristics of the powder blend. Compressed ODTs had good mechanical strength, and their friability was within the official limits (<1%). Best disintegration was observed with formulation F-6 containing 10% w / w of the Plantago ovata husk. It is concluded that the Plantago ovata husk can be used as a disintegrant in the formulation of ODTs.

The objective of present work was to develop taste masked orodispersible tablets of mirabegron. Mirabegron is beta 3 adrenoceptor agonist used to treat overactive bladder. Overactive bladder (OAB) is defined as a symptom syndrome showing feeling of urgency to urinate, typically accompanied by frequent daytime and nocturnal urination, in the absence of proven infection or other obvious pathology. Over active bladders are generally common in geriatrics. Moreover, this drug has a very strong bitter taste. Frequent dosing requires frequent water intake, which further aggregates the condition of over active bladder and bitter taste of drug affects patient compliance. Hence a need arises to mask the bitter taste for development of an ODT which does not require consuming water with every dosage. In this work, the bitter taste of mirabegron was masked by forming a complex with an ion exchange resin tulsion 344. The drug resin complexation process was optimized for resin activation, drug: resin ratio, soaking time and stirring time. In –vitro release studies revealed complete drug elution from the complex within 10 minutes in pH 1.2 buffer. The taste-masked complex was then formulated into palatable orodispersible tablets using a direct compression approach by use of superdisintegrants to achieve a rapid disintegration. The tablets were evaluated for weight variation, hardness, friability, drug content, wetting time, In- vivo disintegration time and in-vitro dissolution time.

The objective of the present investigation was to prepare oro dispersible tablets of ondansetron hydrochloride, because of its application in emesis condition, fast onset of action and avoidance of water is highly desirable. Tablets were prepared by direct compression using sodium starch glycolate and croscarmellose as superdisintegrants, as the combination of these two agents gives better disintegration of the tablet. Microcrystalline cellulose was used as diluent and mannitol, mint flavor, sodium saccharine to enhance the organoleptic properties of tablets. The tablets were evaluated for weight variation, mechanical strength, in vitro disintegration time, in vivo disintegration time, wetting time, and drug release characteristics. Hardness and friability data indicated good mechanical strength of tablets.  The results of in vitro disintegration time and in vivo disintegration time indicated that the tablets dispersed rapidly in mouth within 3 to 5 seconds. Dissolution study revealed faster release rate of ondansetron hydrochloride from the tablets as compared to pure drug and marketed conventional tablet formulation of ondansetron hydrochloride. It was concluded that superdisintegrants addition technique is a useful method for preparing oro dispersible tablets by direct compression method

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.

 The main objective of this study is to explore development of pharmaceutical excipients from the husk obtained from the seeds of Plantago ovata. Husk shows very good swelling property in water due to the major part of mucilage in it. Since swelling is one of the mechanisms of action of some tablet disintegrants, it is thought that the husk powder of Plantago ovata would be able to act as a tablet disintegrant. The powder obtained from the Plantago ovata husk was characterized for micromeritical properties, swelling capacity, hydration capacity, LOD, pH, particle size, foreign particles, ash value and microbial limit tests. Its disintegrant ability in comparison with maize starch was investigated by preparing famotidine tablets via the direct compression method. It was also compared with three marketed tablets of famotidine. The Plantago ovata husk powder, however, showed superior flow, swelling capacity as well as water retention capacity than maize starch. The tablets were characterized for hardness, friability, weight variation, in vitro disintegration study and in vitro dissolution study. The optimized batch F2C comprising of 10% of the Plantago ovata husk powder showed a 15 seconds disintegration time, which was significantly less than tablets prepared from maize starch as well as all three market preparations. Tablets from batch F2C were submitted for short term stability studies and exhibited stable characteristics.

Objective: To evaluate the effect of binder concentration, granule size and distance between punches on mechanical strength and drug release properties of tablets containing Malva verticillata mucilage (MVM) as a binder.Methods: Paracetamol and lactose were converted into wet coherent masses by a liquid solution containing 1-3% w/w MVM as a binder. Granules containing 2% w/w binder was used to investigate the effect of granule size and distance between punches. Compressed tablets were evaluated for crushing strength, disintegration time and in vitro drug release using pharmacopeial methods.Results: Granules containing MVM were found to be free-flowing and compatible with paracetamol. Mechanical strength and drug release properties of mucilage tablets significantly correlated with the amount of MVM binder. Tablet crushing strength was 3.54-7.12 kg/cm2 while disintegration time 7.13-16.67 min. Compression pressure and granule size had no significant effects on drug release properties of mucilage tablets. Crushing strength of mucilage tablets were higher and significantly different (t(26) = 7.9631, p<0.05) from acacia tablets in the tested variables. The cumulative drug release rate of mucilage tablets was also lower than that of acacia tablets in tested concentrations.Conclusion: Properties of tablets containing 2.5% w/w MVM matched the prescribed pharmaceutical limits and hence M. verticillata root mucilage has a great potential to become a new source of tablet binder.

Dispersing Ability

Orodispersible tablets are uncoated tablets which when taken into the mouth, get easily dispersed within 3 min before swallowing. they are also known as orally disintegrating tablets, mouth-dissolving tablets, rapid dissolving tablets fast-disintegrating tablets, fast-dissolving tablets. In this work, sublimation process was used to prepare orodispersible tablets of aspirin by formulating various batches using different concentration of sodium starch glycolate, camphor and cross povidone. An effort was made by using two modes, first, to increase water uptake for the fast dispersion by creating pores by sublimation methods in tablets and second, use of super disintegrantes like sodium starch glycolate to minimise disintegration time and promote fast dispersing ability. Prepared formulations were evaluated for weight variation, content uniformity, friability, hardness, wetting time, disintegration time, in vitro drug release and interaction study by differential scanning calorimetery. The best formulation was selected on the basis of evaluation results.

Aim: The main of the study is to formulate and develop orally disintegrating fast dissolving tablet of Metoclopramide hydrochloride. Material & Methods: Before formulation and development of selected drug, the standard curve in buffer was prepared and absorbance at selected maxima was taken. Then two different disintegrating agents were selected and drug was mixed with disintegrating agents in different ratio. Various Preformulation parameters and evaluation of tablet i.e. disintegration time, dissolution time, friability, hardness, thickness were measured by standard procedure. Result & Discussion: The angle of repose for all the batches prepared. The values were found to be in the range of 30.46 to 36.45, which indicates good flow property for the powder blend according to the USP. The bulk density and tapped density for all the batches varied from 0.49 to 0.54 g/mL and 0.66 to 0.73, respectively. Carr’s index values were found to be in the range of 23.33 to 25.88, which is satisfactory for the powders as well as implies that the blends have good compressibility. Hausner ratio values obtained were in the range of 1.22 to 1.36, which shows a passable flow property for the powder blend based on the USP. The results for tablet thickness and height for all batches was found to range from 4.45 to 4.72 mm and 3.67 to 3.69 mm, respectively. Hardness or breaking force of tablets for all batches was found to range from 32.8 to 36.2 N. Tablet formulations must show good mechanical strength with sufficient hardness in order to handle shipping and transportation. Friability values for all the formulations were found to be in the range of 0.22 % to 0.30 %. Conclusion: Orally disintegrating tablets were compressed in order to have sufficient mechanical strength and integrity to withstand handling, shipping and transportation. The formulation was shown to have a rapid disintegration time that complied with the USP (less than one minute). The data obtained from the stability studies indicated that the orally disintegrating mini-tablets of MTH were stable under different environmental storage conditions.

In the present study we have formulated (F1 to F6) matrix tablets of atenolol and indapamide for the management of hypertension. As in simultaneous estimation of these drugs it was found that a confined release can be formulated. In the formulation of SR matrix tablet by using different concentration of delayed release agent DCP and pregelatinized starch as disintegrant we prepared tablets by wet granulation method. For sustained release action HPMC polymers were used for film coating. Preformulation studies were performed prior to compression. The compressed SR matrix tablets were evaluated for weight variation, hardness, friability, drug content, disintegration time and in vitro drug release using USP dissolution apparatus type 2 (paddle). It was found that the optimized formulation showed 49.33%, 48.90%, 48.52%, 47.65%, 46.84% and 46.51% release for atenolol in 12 hours respectively. However, indapamide released 49.62%, 49.39%, 48.72%, 48.27%, 47.59% and 47.36% at the end of 12 hr. The IR spectrum study revealed that there is no disturbance in the principal peaks of pure drugs atenolol and indapamide. This confirms the integrity of pure drugs and no incompatibility of them with excipients. The stability studies were carried out for the optimized batch for one months and it showed satisfactory results. The kinetic studies of the formulations revealed that diffusion is the predominant mechanism of drug and release follows Zero-order, Super case II transport.
