Cyclodextrins play an important role in the pharmaceutical industry due to their amphiphilic properties and excellent biocompatibility. CD BioGlyco looks forward to providing our customers with professional and rapid solutions in the field of pharmaceutical cyclodextrin development.

The Importance of Cyclodextrins in Pharmaceutical Technology

The central cavity of the cyclodextrin molecule offers a somewhat lipophilic nanoenvironment in which appropriately sized drug parts (or even small drug molecules) can be entered and contained. Therefore, cyclodextrins have been of particular importance in drug delivery and pharmaceutical technologies. For example, the synthesis of novel surface active cyclodextrin derivatives is applied to drug delivery systems. Certainly, cyclodextrins enhance the apparent solubility of drugs as the result of the formation of cyclodextrin/drug inclusion complexes. However, the complexation can also protect drugs from heat, light, hydrolysis, and oxidation, thereby improving the stability of formulations. In other cases, many active pharmaceutical ingredients have undesirable taste and odor, which can lead to low patient compliance, thereby compromising the treatment efficiency, especially for geriatric and pediatric populations. It allows the manipulation of volatile compounds, reduces unpleasant tastes and odors, and decreases the effect of irritating compounds. Moreover, cyclodextrins can modify the release rate of drugs working as excipients for immediate or sustained release. In addition, cyclodextrins are used for optimizing the bioavailability of drugs through chemically modified cyclodextrin derivatives, and the combination of different types of building blocks. However, in recent years cyclodextrins have been shown to participate in various types of non-inclusion complexes with, for example, organic salts and water-soluble polymers. They have also been shown to form aggregates, either alone or in combinations with other excipients. These aggregates can form dispersed drug delivery systems such as micro-and nanoparticles.
