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.

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.

Background: Recent developments in fast dissolving tablets have brought convenience in dosing to pediatric and elderly patients who have trouble in swallowing tablets.The main objective of the present study is to formulate fast dissolving tablet of Lornoxicam by direct compression method.Methods: Guar gum and crospovidone were used as natural and synthetic superdisintegrants respectively. Fast dissolving tablet of Lornoxicam were prepared by direct compression technique using three different approaches; superdisintegrant addition, sublimation, and solid dispersion.Results: IR and DSC studies showed no interaction between the drug and the excipients. All formulation showed disintegration time ranging from 16.09-42.54 second. Wetting time and disintegration time decreased by increasing the super disintegrant concentration from 2.5% to 5% w/w. Formulae L16 gave the best in- vitro disintegration and dissolution results, which would be due to swelling effect of Gaur gum and amorphization of the drug during the solid dispersion preparation.The best formulation L16 was subjected to stability testing for 3 month and results showed no significant change in appearance, hardness, drug content and dissolution profile of the tablets, hence tablet is stable throughout its stability studies.Conclusion: It was concluded that fast dissolving tablets of Lornoxicam were formulated successfully with desired characteristics which disintegrated rapidly; provided rapid onset of action; and enhanced the patient convenience and compliance.JMMIHS,2018;4(1):86-102
