Recently, it has been observed that newly developed drugs are lipophilic and have low aqueous solubility issues, which results in a lower dissolution rate and bioavailability of the drugs. To overcome these issues, the liquisolid technique, an innovative and advanced approach, comes into play. This technique involves the conversion of the drug into liquid form by dissolving it in non-volatile solvent and then converting the liquid medication into dry, free-flowing, and compressible form by the addition of carrier and coating material. It offers advantages like low cost of production, easy method of preparation, and compactable with thermo labile and hygroscopic drugs. It has been widely applied for BCS II drugs to enhance dissolution profile. Improving bioavailability, providing sustained release, minimizing pH influence on drug dissolution, and improving drug photostability are some of the other promising applications of this technology. This review article presents an overview of the liquisolid technique and its applications in formulation development.
