Ondansetron Hydrochloride (OSH) is a sparingly water-soluble drug. The aim of the present investigation was to prepare solid dispersion (SD) of OSH using superdisintegrants as carrier and formulate it as fast dissolving tablets (FDTs) with an objective to improve solubility and enhance dissolution of drug. SD of drug using superdisintegrants like croscarmellose sodium (CCS), crospovidone (CP), sodium starch glycolate (SSG), and low substituted hydroxy propyl cellulose (L-HPC) respectively as carriers was prepared by solvent evaporation method. The prepared SD formulations were characterized by equilibrium solubility, fourier transform infrared spectroscopy (FTIR), X-ray powder diffraction (XRPD), differential scanning calorimetry (DSC) and dissolution study. FTIR spectra revealed no chemical interaction between the drug and superdisintegrants. XRPD and DSC data indicated that OSH was in the amorphous form, which explains the better dissolution rate of the drug from its solid dispers...

Ondansetron Hydrochloride (OSH) is a sparingly water-soluble drug. In this investigation fast dissolving tablets (FDTs) of ondansetron were prepared using different superdisintegrants by sublimation method. FDTs were evaluated for physicochemical properties and in vitro dissolution. The wetting time (10.5s) of formulation batch containing crospovidone (F2) was least and tablets showed fastest disintegration (3.2s). The drug release from FDTs containing superdisintegrants was more as compared to FDTs without superdisintegrant and it was found to be highest (98% drug release after 30 min) with formulation batch containing crospovidone (F2) so it can be concluded as promising formulation.

In the present time, a mouth dissolving tablets become popular over conventional oral solid dosage form as it overcome common problem associated with conventional oral tablet dosage form such as issue in swallowing tablets in paediatric as well as geriatric population as well as avoid first pass metabolism and provide quick onset of action as it starts to absorb directly from oral cavity. Ondansetron HCl is used to prevent nausea and vomiting. In case of vomiting as well as in nausea, drug must require to act quickly to treat therapeutic condition of patient in need thereof. Therefore, combining Mouth dissolving technology with Ondansetron HCl as active pharmaceutical ingredient could be potential strategy to provide quick onset of action without swallowing entire tablet. Therefore, aim of the present research work is to fabricate mouth dissolving tablets of Ondansetron HCl using different concentration, i.e. 3%, 5% and 9%w/w, of different water insoluble super-disintegrants, namely...
The demand for fast dissolving tablets of OndansetronHCl has been growing during the last decade specially for the geriatric and pediatric patients. OndansetronHCl is a recognized as antiemetic drug, so development of an FDT OndansetronHCl and to evaluate the effect of various concentrations of superdisintegrant and binder on its disintegration time and release profile was the prime objective of this research work. Methods: Tablets were prepared by high pressure homogenization followed by direct compression. 22 factorial design was applied in which concentration of superdisintegrant and binder were taken as independentvariables and disintegration time and percentage release were taken as dependent variables. The prepared tablets wereevaluated for weight variation, hardness, friability, disintegration time, content uniformity, and % drug release. Direct compression process was selected for this formulation of ODT tablets, because porous nature is more in direct compression blend than...

Background: Ondansetron hydrochloride is a serotonin sub type-3 (5-hydroxytryptamine-3) receptor antagonist. It is a widely used drug for the treatment of post-operative nausea and vomiting (PONV) and chemotherapy-induced nausea and vomiting. The recommended oral dose regimen of ondansetron hydrochloride is 8 mg, three times a day up to 1 week and it is having a short biological half-life, approximately 3-5 h. Therefore, there is a need to once daily controlled release drug delivery systems to extend its therapeutic action entire the day. Aim: The main object of the present work deals with the development of pH-independent controlled release tablets of ondansetron HCl using pH modulating technique. Materials and Methods: Ondansetron HCl is a weakly basic drug belongs to BCS Class-II and it is showing distinct pH-dependent solubility. The solubility exhibits high solubility at low pH (pH 1.2) at 37°C (23.3 mg/ml); however, it exhibits poor solubility at higher pH (6.8 pH phosphate bu...
Effect of drug-carrier interaction on the dissolution behavior of solid dispersion tablets
Pharmaceutical Development and Technology, 2010
The objective of this study was to compare the dissolution behavior of tablets prepared from solid dispersions with and without drug-carrier interactions. Diazepam and nifedipine were used as model drugs. Two types of carriers were used; polyvinylpyrrolidone (PVP K12, K30 and K60) and saccharides (inulin 1.8 kDa, 4 kDa and 6.5 kDa). Solid dispersions with various drug loads were prepared by lyophilization. It was found that the drug solubility in aqueous PVP solutions was significantly increased indicating the presence of drug-carrier interaction while the drug solubility was not affected by the saccharides indicating absence of drug-carrier interaction. X-ray powder diffraction and modulated differential scanning calorimetry revealed that all solid dispersions were fully amorphous. Dissolution behavior of solid dispersion tablets based on either the PVPs or saccharides was governed by both dissolution of the carrier and drug load. It was shown that a fast drug dissolution of solid dispersions with a high drug load could be obtained with carrier that showed interaction with the drug.

The poorly water soluble drugs tend to have low bioavailability and this can be improved by several methods. Solid dispersion is a promising formulation approach to improve solubility and dissolution and ultimately oral bioavailability of these drugs. The aim of this study was to prepare and characterize solid dispersion of anti-diabetic glimepiride, a BCS class II drug, with the hydrophilic carrier PVP K30 by solvent evaporation and microwave induced fusion methods. Scanning electron microscopy (SEM), X–ray powder diffractometry (XRD) and differential scanning calorimetric (DSC) were used to evaluate the physical state of the drug. The solid dispersions were also evaluated for drug content, solubility and dissolution studies. Solid dispersions prepared by solvent evaporation method were showed maximum enhancement of solubility and dissolution in comparison to that prepared by other method.
