Abstract

Solid dispersions have engrossed substantial attention as an effectual means of refining the dissolution rate and hence the bioavailability of a variety of hydrophobic drugs. In this review, it is intended to discuss the future prospects related to the area of solid dispersion manufacturing. 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 presents a challenge to the formulation scientists. Solid dispersion techniques have attracted considerable interest of improving the dissolution rate of highly lipophilic drugs thereby improving their bioavailability by reducing drug particle size, improving wettability and forming amorphous particles. This review article discusses the various preparation techniques and characterization for solid dispersion and compiles some of the recent technology transfers in the form of patents.
