This article covers information about cyclodextrin and its various derivatives, its different manufacturing process, physicochemical properties, advantages, and recent advancements. There are various advantages of CD-based inclusion complexes, such as enhancement of solubility, bioavailability, and stability and reduction of irritation caused by the drug. Moreover, they are used as odor and taste enhancers and also prevent incompatibility by physically isolating the incompatible drug components in drug formulation. CD and its derivatives are extensively employed as solubilizers in the manufacturing of parenteral and oral dosage forms. Inclusion complexes formed by CDs with appropriately sized guest molecules improve drug water solubility, physical-chemical stability, and bioavailability. Simultaneously CDs prevent the drugs from degradation like oxidation, hydrolysis, and photodegradation and extend the shelf life of the drug. The manuscript also highlights patents and exclusive branded formulations of modified CDs. It also discusses the different examples of chemically modified CDs, i.e., captisol, sulfobutyl ether-β-CD, hydroxy propyl betadex, randomly methylated β-CD, methyl β-CD, and hydoxy propyl γ-CD, all are used in the various dosage forms.
