The current article aims with the introduction of newer solubility enhancing technique as Liquisolid-pellet. The majority of newly invented molecules comes under the biopharmaceutical classification system (BCS) Class II, IV indicating poor solubility and thereby poor bioavailability. Liquisolid Compaq is one of the solubility enhancement techniques used for improving solubility and dissolution of the molecule by incorporating non-volatile solvent followed by carrier and coating agents. However, this technique is only applicable to potent molecules as a higher dose resulted in inconvenience to the patient and difficult to swallow. Another drawback of this method is not suitable for pilot plant scale-up. Liquisolid pellet technique overcoming all limitations of Liquisolid Compaq and offers good compaction, flowability, dose accuracy, less gastric irritations, and better bioavailability. In the Liquisolid-Pellet technique, powdered material received from Liquisolid Compaq is further moistened with granulating fluid to provide enough plasticity. The material is subjected to extrusion using an extruder to generate extrudates. The extrudates are placed under the spheronizer to form spherical particles as Pellets. The pellets are mainly prepared by extrusion-spheronization and hence, articles elaborate details of extruders and spheronizers, their specifications as well as factors, which strongly impart processing. These pellets are filled in capsules according to their dose and utilized as an immediate release or sustained release. The literature related to this review was collected from Science Direct, PubMed, Google Scholar, Google, USPTO, etc. from 1998 to 2020 with the following key-words.
