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.

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.

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.

Objective: The aim of this study was to formulate ketoconazole (keto) as oral floating in situ gel to slow the release of keto in the stomach.Methods: Sodium alginate (Na alginate) was used as a primary polymer in the preparation of the in situ gel and was supported by the following polymers: guar gum (GG), hydroxypropyl methylcellulose (HPMC) K4M, K15M and carbapol 940 as viscosity enhancing agents. As a consequence, and to complete the gelation process of above formulations was by adding the calcium carbonate (CaCO3). The in situ gels were investigated by the following tests: floating lag time, floating duration, viscosity, drug content, in vitro gelling studies and in vitro release study.Results: The study showed that the faster release was obtained with F1 which contained Na alginate alone. Additionally, reduction in Na alginate concentration resulted in significant increase in drug release. It was also noted that the increase in GG (viscosity enhancing polymer) concentration resulted in non-significant decrease in percent drug release and the reduction in CaCO3 concentration led to significant increase in drug release. Moreover, the release of drug was also affected by grade of viscosity enhancing polymer, the faster release was observed with the formula which contained a polymer of low viscosity (HPMC K4M) and an opposite result was with the high viscosity polymer (HPMCK15M).Conclusion: This study showed the formulation of Na alginate with GG and CaCO3, led to gain floating in situ gel and a sustained release of keto.

ABSTRACT: The purpose of the study was to prepare orally disintegrating tablets (ODTs) of mosapride citrate for dogs with fast disintegration and low cost. The ODTs were developed by varying the components and the ratio of excipients. A direct compression method was used. The properties of the ODTs, including hardness, friability, active ingredient content, and in vitro disintegration time, were investigated, and an economic analysis of the formulations was performed. For all formulations, friability was less than 1%, and the hardness varied from 37.69±4.08 to 48.73±5.62 N, which indicated that the tablets had sufficient mechanical integrity to withstand packaging and carrying. Results showed that Formulation (F) 2, containing 5% sodium carboxymethyl starch; F3, containing 5% low-substituted hydroxypropylcellulose; and F5 had not only shorter disintegration times but also lower costs, which were suitable for mosapride citrate ODTs. Although F1, contained 5% croscarmellose sodium, and F4, contained 5% crospovidone, with shorter disintegration times, the costs of F1 and F4 were 25.8% and 22.6% higher than that of F5, respectively. Results also revealed that the disintegration time of F5 was not significantly different from those of F1, F2, F3, and F4 (p>0.05), all of which contained superdisintegrants. Without superdisintegrants, F5, which contained a mixture of microcrystalline cellulose, mannitol, and lactose, was also able to achieve a short disintegration time and to meet the requirements of ODTs for dogs.
