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.

AbstractIn the present investigation comparison of three different superdisintegrants was carried out by formulating orally disintegrating tablets. Promethazine HCl was used as model drug which is an antiemetic drug. Sodium starch glycolate, croscarmellose and crospovidone were selected as superdisintegrants and each one was used in three different concentrations (2%, 3.5% and 5%). The drug-polymer compatibility was ruled out by FTIR studies. A total of nine formulations (PF1-PF9) were made by direct compression. All prepared formulations were evaluated for weight variation, hardness, friability, drug content, disintegration time, wetting time and in vitro drug release parameters. The results of the evaluation parameters for all the nine formulations of promethazine HCl were within the standard limits. The in vitro drug release for promethazine HCl tablets of all the formulations (PF1-PF9) was carried out using phosphate buffer pH 6.8 as dissolution medium. Among all the formulations the tablets formulated with crospovidone (PF7-PF9) have shown 91.43 - 98.43% (maximum) drug release at the end of 10 min than sodium starch glycolate and croscarmellose, hence from the present work, it concluded that among three superdisintegrants crospovidone is the ideal superdisintegrant for formulating oral disintegrating tablets for promethazine HCl.

The aim of the present study was to develop and evaluate orodispersible tablets of domperidone by  direct compression method. Sodium starch glycolate ( SCG ), Kollidone CLSF and sodium bicarbonate were used as  disintegrants to achieve the desired disintegration time required for orodispersible tablets. To mask the bitter taste of  drug, impart sweetness and to offer a better feeling in mouth, saccharin sodium, aspartame, citric acid, menthol and  lemon flavor were also added. Mannitol and lactose were used as sugar based multifunctional diluents. The prepared  tablets were evaluated for their physical (hardness, friability, weight variation), organoleptic (taste, mouth-feel, color)  and functional (disintegration time) properties and for the drug content. The excipients were used in various  concentrations in order to optimize the desired properties. SCG and Kollidone CLSF, used in 5.5% and 4%  respectively, gave satisfactory disintegration time using BP instrument and within the mouth. Combination of  saccharin sodium (1.5%) and aspartame (3%) along with mannitol (40%) and other excipients effectively masked the  bitterness and provided satisfactory sweetness level. Incorporation of 0.05% menthol provided excellent mouth  feeling as assessed by a panel of volunteers. Hardness and friability values were also optimized in the formulations to  produce tablets of acceptable physical stability and mechanical strength. Weight variation and drug content of all  formulations fully complied with the official specifications.   DOI: http://dx.doi.org/10.3329/dujps.v10i2.11791   Dhaka Univ. J. Pharm.

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 purpose of this study was to enhance the dissolution pattern of the practically water-insoluble diuretic drug, furosemide through its formulation into liquisolid tablets.Methods: A mathematical model was used to formulate four liquisolid powder systems using polyethylene glycol 400 as a non-volatile water miscible liquid vehicle. The liquid loading factors of the vehicle were used to calculate the optimum quantities of carrier (Avicel PH 102) and coating materials (Aerosil 200) needed to prepare acceptably flowing and compactible powder mixtures and (R) ratio used was 25. The liquisolid tablets were evaluated for weight variation, percent friability, hardness, content uniformity, disintegration time and in vitro drug release profile. Drug and the prepared systems were characterized by fourier transform infrared spectroscopy (FTIR), differential scanning calorimetry (DSC) and powder x-ray diffraction (PXRD) studies.Results: The enhanced dissolution rate due to the increased wetting properties and the large available surface areas for dissolution were obtained in case of the liquisolid tablets. The selected optimal formulation (F2) of 50% drug concentration released 90% of its content during the first 10 min compared to 65% of DCT. FTIR studies revealed that there was no interaction between drug and polymers. DSC and PXRD indicated conversion of crystalline to amorphous form of furosemide. Conclusion: The dissolution rate of furosemide can be enhanced to a great extent by liquisolid technique.

The foremost objective of this research was to compare and evaluate natural super disintegrants with synthetic super disintegrants for the preparation of the orodispersible tablet. Tropisetron hydrochloride is widely used as an antiemetic drug, which is a potential drug candidate for developing an orodispersible tablet for quick onset of action. Various formulations were prepared using different concentrations (5%, 7.5%, and 10%) by direct compression method of natural super disintegrants (Banana power and Cassia tora powder) and synthetic super disintegrants (Croscarmellose sodium, Crospovidone, and Sodium starch glycolate). The compatibility studies between the drug and excipients were carried out using FTIR spectroscopy before tablet formulation. The pre-compression parameters were evaluated for additive properties. Standardization of banana powder was done by various parameters like extractive value, ash value, loss on drying, TLC identification test, etc. Post-compression parameters like hardness, weight variation, friability, thickness, the time required for disintegration, wetting time, the release of drug in-vitro, and in-vitro dispersion time of the tablets were evaluated. The disintegration time and in-vitro drug release of optimized formulation (F2) were found to be 4.66±1.15 secs and 99.25±0.15%. The optimized formulation (F2) was subjected to stability studies (40 C& 75 % RH) for one month. The results were shown that natural super disintegrants require less disintegration time as compared to synthetic super disintegrants. Hence present study reveals that the orodispersible tablets prepared using Banana powder and Cassia tora powder is super disintegrants that shown better appearance and rapid disintegration time.

Orodispersible tablets (ODTs), also known as fast melt, quick melts, fast disintegrating have the unique property of disintegrating in the mouth in seconds without chewing and the need of water. Oral bioavailability of Atorvastatin Calcium is low (14%) and shows extensive intestinal clearance and first-pass metabolism, which is the main cause for the low systemic availability. In the present work, orodispersible tablets of Atorvastatin calcium were prepared by direct compression method using Hibiscus rosa sinesis mucilage as natural superdisintegrant with a view to enhance patient compliance and to avoid hepatic first pass metabolism and to improve its bioavailability. The prepared batches of tablets were evaluated for hardness, friability, drug content uniformity, wetting time, water-absorption ratio and in-vitro dispersion time. Short-term stability studies on the promising formulation indicated that there are no significant changes in drug content and in vitro dispersion time. Keywords: Orodispersible tablet, Atorvastatin Calcium, lipid-lowering agent, Superdisintegrant, Hibiscus Rosa Sinensis, Bioavailability, solubility.

In the present work, orodissolving tablets of Efavirenz were prepared by direct compression method with a view to enhance patient compliance. A 23 full factorial design was applied to investigate the combined effect of three formulation variables. Amount of crospovidone, croscarmellose sodium and sodium starch glycolate were used as superdisintegrant material along with direct compressible mannitol to enhance mouth feel. The prepared batches of tablets were evaluated for hardness, friability, weight variation, disintegration time, wetting time, drug content and in-vitro dissolution studies. Based on wetting time, disintegration time, the formulation containing crospovidone (5% w/v), carscarmellose sodium (5% w/v) and sodium starch glycolate (8% w/v) was found to be promising and tested for in-vitro drug release pattern (in 0.1 N HCl), short term stability and drug- superdisintegrants interaction. Surface response plots are presented to graphically represent the effect of independent variables (conc. of superdisintegrants) on the in-vitro dissolution time. The validity of the generated mathematical model was tested by preparing extra-design check point formulation. The formulation showed nearly faster drug release compared to the conventional commercial tablet formulation. Stability studies on the optimized formulation indicated that there was no significant change found in physical appearance, hardness, disintegration time, drug content and in-vitro drug release.

The aim of present work was the development of fast dissolving oral film of Loratadine to overcome the limitations of current routes of administration, to provide immediate action and increase the patient compliance. To improve the bioavailability of the drug, fast dissolving oral film were formulated using different grades of Hydroxy Propyl Methyl Cellulose(HPMC) and various plasticizers like Polyethylene Glycol(PEG) 400, glycerol, Propylene glycol(PG) by solvent casting method. The formulated films were evaluated for film thickness, surface pH, folding endurance, weight variation, % moisture loss, exvivo permeation study, tensile strength, % elongation, drug content uniformity, in vitro dissolution studies,in vitro disintegration test and in vivo study. The optimized formulation (F9) containing HPMC E5 and glycerol showed minimum disintegration time (10.5 s), highest in vitrodissolution (92.5%) and satisfactory stability. Ex vivo permeation study of optimized formulation showed a drug release of 80.6% within 10 min. The milk induced leucocytosis inrat proved that fast dissolving oral films of Loratadine produced a faster onset of action compared to the conventional tablets. These findings suggest that fast dissolving oral film of Loratadine could be potentially useful for treatment of allergy where quick onset of action is required.

Objective: The objective of the current study was to evaluate the quality control parameters of seven brands of levofloxacin 500 mg film-coated tablet available in the Yemeni market. Methods: Physicochemical parameters assay was performed for seven brands of levofloxacin 500 mg film-coated tablet. Each brand was subjected to official and unofficial in vitro quality control tests, including weight variation, thickness, hardness, friability, disintegration, dissolution, and content uniformity assay by High-Performance Liquid Chromatography (HPLC). Results: Out of seven, six brands of levofloxacin 500 mg film-coated tablet passed official specified assay tests according to the United States Pharmacopeia (USP) specifications. They showed a similar profile of thickness ranged between±0.01 and 0.10%, friability ranged between 0.01% and 0.34%, disintegration time ranged between 3.00 and 15.00 min, dissolution percentage ranged between 90.650 and 103.05 and content uniformity ranged between 93.62 and 107.12%. Regarding weight variation and hardness, six brands passed the weight variation test and only three brands showed optimum range (10-20 kg) of hardness test. Only one brand failed to pass the weight variation test, and four brands failed to pass the optimum range (10-20 kg) of hardness. Conclusion: There are no remarkable differences between the seven brands regarding in vitro quality control tests of content uniformity, thickness, friability, disintegration, and dissolution. Even though four brands were above the optimum range of hardiness, they showed complete disintegration and dissolution within the acceptable limit. Regular assessment of marketed drugs is required to ensure bioequivalent to their innovators.
