In the present work, gliclazide loaded polyethylene glycol (PEG) based solid dispersions were prepared using fusion method in order to improve the solubility and dissolution rate of gliclazide. The compatibility of the drug with various formulation components was established. Solid dispersions (SDs) of gliclazide and polyethylene glycol (PEG 4000, 6000 and 8000) at three mass ratios (1:1, 1:3, ...

The objective of the study was to enhance the solubility of carvedilol phosphate and to formulate it into non-effervescent floating tablets using swellable polymers. Solid dispersions (SD) of carvedilol were prepared with hydrophilic carriers such as polyvinylpyrrolidone and poloxamer to enhance solubility. Non-effervescent floating tablets were prepared with a combination of optimized solid di...

Lamotrigine is used in the treatment of CNS disorders, particularly epilepsy; pain; oedema; multiple sclerosis and psychiatric indications including bipolar disorder. Lamotrigine belongs to biopharmaceutical classification systems, BCS class II (Low solubility & High permeability). In addition, it requires immediate therapeutic action hence the main objective of this study is to improve the sol...

Solubility is an important physicochemical factor affecting absorption of drug and there by its therapeutic effect. About 40% of newly discovered drugs are lipophilic and failed to reach market due to their poor water solubility. Solid dispersions proved to have tremendous potential for improving drug solubility. Orlistat is a poor water soluble substance possessing anti-obesity property; in th...

Differential scanning calorimetry and X-ray diffraction play a prominent role in the characterization of lipid nanoparticle (LNP) dispersions. This review shortly outlines the measurement principles of these two techniques and summarizes their applications in the field of nanodispersions of solid lipids. These methods are particularly useful for the characterization of the matrix state, polymor...

Purpose: To evaluate the physicochemical properties of clotrimazole (CLT) solid dispersion with Pluronic F127 (PLU). Methods: Solid dispersions of the antifungal drug, clotrimazole, were prepared with Pluronic F127 using grinding (PM) and fusion (FUS) methods. Physicochemical characterization of the dispersions were performed using differential scanning calorimetry (DSC), x-ray powder diffracti...

In the present study solid dispersions of the antifungal drug Ketoconazole were prepared with Pluronic F-127 and PVP K-30 with an intention to improve its dissolution properties. Investigations of the properties of the dispersions were performed using release studies, Differential scanning calorimetery (DSC), X-ray powder diffraction (XRD) and Fourier transform infrared (FTIR). The results obta...

An EMD model for nanocolloidal dispersions considering the interaction between atoms within solid particles is developed for viscosity calculation and studying the effect of the particle size and volume fraction. Strong oscillations are observed in the pressure tensor autocorrelation function. Elimination of this oscillation is achieved by adjusting the potential among atoms of nanoparticles to...

Abstract—Cefixime, a BCS class II drug, is insoluble in water but freely soluble in acetone and in alcohol. The aqueous solubility of cefixime in water is poor and exhibits exceptionally slow and intrinsic dissolution rate. In the present study, cefixime and βCyclodextrin (β-CD) solid dispersions were prepared with a view to study the effect and influence of β-CD on the solubility and dissoluti...
