Cyclodextrin-Based Liposomes Production
Using dual approach has emerged as a novel plan to tackle the problems of poor aqueous solubility and low rate of dissolution in drug formulation. Therefore, Creative Biostructure combines the cyclodextrins and nanotechnology to develop cyclodextrin-based liposomes that deliver hydrophobic drugs.
How Cyclodextrin-Based Liposomes Work
Cyclodextrins (CDs) are cyclic oligosaccharides formed from glucopyranose units. With hydrophobic cavity inside and hydrophilic outside, they can form complexes with hydrophobic compounds. The CD/drug inclusion complex provide an alternative approach to encapsulate hydrophobic drugs in the aqueous phase of liposome instead of incorporating them into the phospholipids membrane bilayers. This double-loading technique provides better therapeutic effects in the following aspects.
- By complexing with the cyclodextrin and their derivatives, the solubility, stability, and bioavailability of drug can be improved, along with reduced toxicity and modified physicochemical characteristics.
- Cyclodextrin-based liposomes increase the drug loading capacity and entrapment efficiency, prolong the existence of the drug in systemic circulation, and provide controlled, sustained, or targeted release. These liposomes also prevent the dissociation of CD/drug complex and renal excretion of cyclodextrins.
- Relatively low cost.
Cyclodextrin-Based Liposomes Applications
Cyclodextrin-based liposomes is a promising carrier system to preserve volatile and hydrophobic drugs; and provide an access to explore their applications in pharmaceutical, cosmetic and food industry. In addition to liposomes, cyclodextrin-based nanocarriers could be expanded by combination with other carriers like niosomes, nanosponges, micelles, Short Interfering RNA, etc. This complementary carrier system could broaden the scope and accessibility of present and future therapeutic agents.
