Abstract

Background: Solubility is one of the significant pre-formulation properties which regulate the desired concentration of drug in the systemic circulation. Most of the newly discovered chemical entities show poor solubility which consequently leads to poor bioavailability. To enhance the bioavailability of such type of drugs is a big challenge for pharmaceutical scientists. Liquisolid technology is a new and advanced technology used to transform the liquid medication into dry, free-flowing and easily compressible dosage form incorporation with the carrier and coating material.

Objectives: This review represents the technical perspective of Liquisolid technologies that overcome the demerits of classic formulation strategies and amend the bioavailability of the poorly soluble drug. This technique is also approaches the stability, hygroscopicity and agglomeration issue which are mainly occurring in other techniques for solubility enhancement.

Conclusion: Several technologies have been utilized to minimize the solubility problem but due to the complicated and expensive machinery fails to achieve the desired bioavailability of the poorly soluble drugs. Therefore, Liquisolid technology has been introduced as an innovative and promising technique that recovers the demerits of classic formulation strategies and also improves the bioavailability of the poorly soluble drug. This article exhibits the technical approach of the liquisolid system by improving the solubility as well as bioavailability of water-insoluble drugs.

Keywords: Solubility, liquisolid, dissolution, bioavailability, poorly soluble drugs, hygroscopicity.
