Solid Dispersion - a Novel Approach for Enhancement of Bioavailability of Poorly Soluble Drugs in Oral Drug Delivery System
It has been estimated that nearly 35-40 % of drugs suffer from poor aqueous solubility and it affects the absorption of drug from gastrointestinal tract that leads to high inter and intra subject variability, poor oral bioavailability, increase in dose, reduction in therapeutic efficiency and finally failure in formulation development. Various formulation strategies like micronization, solubili...
متن کاملPharmaceutical 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 ...
متن کاملSolubility 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...
متن کاملNanocrystal Technology For Oral Delivery of Poorly Water-Soluble Drugs
Nanotechnology has been improving and has a variety of application fields. One of the major application areas of nanotechnology in pharmacy is nanoparticular drug delivery systems. Preparation of drug nanocrystals to improve the solubility of poorly water-soluble drugs for oral delivery is also one of the important applications. Nanocrystal dispersions comprise water, active drug substance and ...
متن کاملSolid Dispersion – a Promising Novel Approach for Improving the Solubility of Poorly Soluble Drugs
Solid dispersions is an efficient means of improving the dissolution rate and hence the bioavailability of a range of poorly soluble drugs. This article reviews the various types of solid dispersion, preparation techniques for solid dispersion and compiles some of the recent technologies. Some of the practical aspects to be considered for the preparation of solid dispersions, such as selection ...
