ABSTRACTObjective: The current research work is intended to formulate propranolol HCl (PLH) as orally disintegrating tablet (ODT). 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.

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.

Background: Fast dissolving or orodispersible tablets are highly desirablein groups such as children, uncooperative, nauseated, or those on reduced water intake to ease the difficulties associated with swallowing the conventional solid dosage forms. Objectives: The work aimed to evaluate the disintegrant property of sorghum starch-silicon dioxide co-processed mixture in the formulation of chlorpheniramine orodispersible tablets. Method: Different batches of orodispersible tablets of chlorpheniramine maleate (4 mg) were prepared by direct compression method using Avicel® as a bulking agent and four different types of disintegrants (sorghum starch, co-processed sorghum starch-colloidal silicon dioxide, sodium starch glycolate and croscarmellose sodium) at varying concentrations (5, 10 and 20 %). The formulated tablets were subjected to weight variation test, thickness, crushing strength, friability test, wetting time, water absorption ratio, disintegration test and in-vitro dissolution study. Results: For tablets above 250 mg, it is expected that not more than two tablets should deviate from the average weight by 5% and none should deviate by more than 10%, all the formulations yielded tablets within this specification. The disintegration time of tablets containing 10% of disintegrants was all less than 60 s except those containing sorghum starch (SS) which took a long time. Similarly, the time taken to release 50 % of the drug (t50%) for tablets containing 10% sorghum starch was 25 s, 5 s for tablets containing 10% sorghum starch-colloidal silicon dioxide excipient and 8 s for tablets containing 10% of either croscarmellose sodium or sodium starch glycolate. The differential scanning calorimetry study results suggested that the drug and the excipient are compatible. Conclusion: The results show that sorghum starch-silicon dioxide co-processed mixture can be used as an alternative to croscarmellose sodium and sodium starch glycolate in orodispersible tablet formulations.
