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.

Sildenafil citrate is an oral therapy for erectile dysfunction (ED).  Sildenafil, a selective inhibitor of cyclic guanosine monophosphate-specific phosphodiesterase type 5 (PDE5), has been reported to be effective in men with ED associated with diabetes and prostate cancer, and in psychogenic ED.  The main objective of this study is to prepare more effective, rapidly disintegrating and rapid onset of action sildenafil oral tablets. Sildenafil tablets were prepared using the newly introduced Pharmaburst® as a direct compression vehicle in comparison with the well-known excipients, namely mannitol, anhydrous lactose and primojel. The formula containing Pharmaburst® showed the most rapidly-disintegrating effect (15 sec) compared to the other formulations. Thus, Pharmaburst® can be utilized as an effective direct compression vehicle as well as a superdisintegrant with very rapid disintegration time in vitro and in the oral cavity. The rapidly-disintegrating sildenafil tablets showed maximum serum concentration within only two minutes (Cmax of 0.76 µg) by applying the tablets to the oral cavity of rabbits, whereas, the conventional sildenafil tablets have a comparatively lower Cmax (0.56µg) through about 45 minutes.

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.
