Solid dispersion, defined as the dispersion of one or more active ingredient in a carrier or matrix at solid state, is an efficient strategy for improving dissolution of poorly water-soluble drugs.

Itraconazole (ITZ) is an oral antifungal drug belongs to triazole group. However, ITZ has low and pH.
Molecular dispersion of two various compounds known as a solid dispersion. It is normally a hydrophobic drug (i.e., curcumin in a solid hydrophilic carrier or matrix) (Dhirendra et al., 2009.
Keywords: Solid dispersion, Carriers, Solubility, Dissolution rate,. Journal of Scientific and Innovative Research 687 Classification of solid dispersions The drug can be dispersed molecularly, in amorphous particles (clusters) or in crystalline particles by melting or solvent method. Therefore, based on their molecular arrangement, different types of solid dispersions (SDs) can be.
Solid Dispersion: Methods and Polymers to increase the solubility of poorly soluble drugs Ladan 1Akbarpour Nikghalb, . Although solid dispersions have tremendous potential for improving drug solubility and only a few marketed products using this approach. There are various methods available to improve the solubility of the new drug in which solid dispersion emerged promising. A Solid.
The aim of this study was to confirm whether light anhydrous silicic acid (Aerosil) could exhibit a stabilizing effect on the physical stability of solid dispersion under humidified conditions. Ternary solid dispersions consist of 50% troglitazone, and various ratios of polyvinyl pyrrolidone and Aerosil were prepared using the co-milling method and then evaluated for their crystallizing.

Solid dispersion is defined as dispersion of one or more active ingredients (hydrophobic) in an inert carrier (hydrophillic) at solid state prepared by melting (fusion) method, solvent, or melting solvent method. When the solid dispersion comes in contact with the aqueous medium, the inert carrier dissolves and the drug is released, the increased surface area produces a higher dissolution rate.

Solid dispersion is one of the most promising approaches for solubility enhancement. Currently only 8% of new drug candidates have both high solubility and permeability. More than 60% of potential drug products suffer from poor water solubility. In solid dispersion particle size of drug is reduced or a crystalline pure drug is converted into amorphous form and hence the solubility of drug is.

The physical mixture and solid dispersion (s) were characterized for drug-carrier interaction, drug content, solubility and dissolution rate. The solubility of drug increased with increasing polymer concentration. The dissolution rate was substantially improved for carvedilol from its solid dispersion compared with pure drug and physical mixture. As indicated from X-ray diffraction pattern and.

Improving oral bioavailability of drugs those given as solid dosage forms remains a challenge for the formulation scientists due to solubility problems. The dissolution rate could be the rate-limiting process in the absorption of a drug from a solid dosage form of relatively insoluble drugs. Therefore increase in dissolution of poorly soluble drugs by solid dispersion technique represents a.
Solid dispersion (SD) is defined as the dispersion of one or more active ingredients in inert carriers at solid state prepared by fusion, solvent, or solvent-fusion methods (Chiou and Riegelman, 1971; Ford and Rubinstein, 1978). It has been widely used to improve the dissolution rate, solubility and oral absorption of poorly water-soluble drugs (El-Badry and Fathy, 2005; El-Badry and Fathy.
