Abstract

The versatile pharmaceutical material cyclodextrin’s (CDs) are classified into hydrophilic, hydrophobic, and ionic derivatives. By the early 1950s the basic physicochemical characteristics of cyclodextrins had been discovered, since than their use is a practical and economical way to improve the physicochemical and pharmaceutical properties such as solubility, stability, and bioavailability of administered drug molecules. These CDs can serve as multi-functional drug carriers, through the formation of inclusion complex or the form of CD/drug conjugate and, thereby potentially serving as novel drug carriers. This contribution outlines applications and comparative benefits of use of cyclodextrins (CDs) and their derivatives in the design of novel delivery systems like liposomes, microspheres, microcapsules, nanoparticles, cyclodextrin grafted cellulosic fabric, hydrogels, nanosponges, beads, nanogels/nanoassemblies and cyclodextrin-containing polymers. The article also focuses on the ability of CDs to enhance the drug absorption across biological barriers, the ability to control the rate and time profiles of drug release, drug safety, drug stability, and the ability to deliver a drug to targeted site. The article highlight’s on needs, limitations and advantages of CD based delivery systems. CDs, because of their continuing ability to find several novel applications in drug delivery, are expected to solve many problems associated with the delivery of different novel drugs through different delivery routes.
