Interest- ingly, cyclodextrins can be dissolved in water ( fig. Cyclodextrins are a family of cyclic oligosaccharides composed of α- ( 1, 4) linked glucopyranose subunits. Cyclodextrins are useful molecular chelating agents. They possess a cage- like supramolecular structure, which is the same as the structures formed from cryptands, calixarenes, cyclophanes, spherands and crown ethers. 1) introduction this short review will address a number of issues associated with the use of cyclodextrins ( cds) to enhance the formulation and delivery of problematic drugs. These cyclic structures contain a lipophilic central cavity and a hydrophilic outer surface ( fig. The article will take the form of a number of questions that we have been asked by industrial, academic, and regulatory colleagues over the years. Cyclodextrins are useful functional excipients that have enjoyed widespread attention and use.
Characteristics cyclodextrins are cyclic oligosaccharides made up of a number of dextrose units of ( α- 1, 4) - linked α- d- glucopyranose. 0 α- cyclodextrin, β- cyclodextrin, γ- cyclodextrin, and their hydrophilic derivatives are virtually non- toxic upon orally administered because of their low bioavailability. Β- cyclodextrin, and γ- cyclodextrin range from 4. The basis for this popularity from a pharmaceutical standpoint is the ability of these materials to. Introduction to the formation of inclusion complexes with cyclodextrins cyclodextrins ( cds) are considered valuable compounds that can be applied in different industrial fields such as food or pharmaceutical, and so on ( ogunbadejo & al- zuhair, ).
