Insoluble Polymers in Solid Dispersions for Improving Bioavailability of Poorly Water-Soluble Drugs

Solid Dispersions: An Overview To Modify Bioavailability Of Poorly Water Soluble Drugs

Solid dispersions as strategy to improve oral bioavailability of poor water soluble drugs.

Solid dispersions are one of the most promising strategies to improve the oral bioavailability of poorly water soluble drugs. By reducing drug particle size to the absolute minimum, and hence improving drug wettability, bioavailability may be significantly improved. They are usually presented as amorphous products, mainly obtained by two major different methods, for example, melting and solvent...

Solubility Enhancement of Poorly Water Soluble Drugs by Solid Dispersion

Solid dispersions have been employed to enhance the dissolution rates of poorly water-soluble drugs. Many approaches have been investigated for the preparation of solid dispersions. This paper reports the various solubility enhancement strategies in solid dispersion. The approaches described are fusion (melting), solvent evaporation, lyophilization (freeze drying), melt agglomeration process, e...

Pharmaceutical Technologies for Enhancing Oral Bioavailability of Poorly Soluble Drugs

The oral bioavailability of BCS (biopharmaceutics classification system) class II drugs with poor solubility and reasonable permeability is limited by the drug dissolution step from drug products. Though prodrug approach is an exciting way of improving the oral bioavailability, it requires extensive studies to establish the safety profile of prodrugs in humans. In view of the increasing market ...

Nanonization strategies for poorly water-soluble drugs.

Poor water solubility for many drugs and drug candidates remains a major obstacle to their development and clinical application. Conventional formulations to improve solubility suffer from low bioavailability and poor pharmacokinetics, with some carriers rendering systemic toxicities (e.g. Cremophor(®) EL). In this review, several major nanonization techniques that seek to overcome these limita...
