Cyclodextrin-Based Formulations: A Non-Invasive Platform for Targeted Drug Delivery.

Area of Science:

• Pharmaceutical Sciences
• Nanomedicine
• Drug Delivery Systems

Background:

• Cyclodextrins (CDs) are effective pharmaceutical excipients.
• CDs form water-soluble inclusion complexes with poorly soluble drugs.
• Extensive research has focused on CDs in nanomedicine over the past 30 years.

Purpose of the Study:

• To review the efficacy and recent applications of CDs in non-invasive drug delivery.
• To provide an overview of CD properties, mechanisms, and toxicology for ophthalmic and nasal administration.
• To summarize the development of CD-based nanocarriers for targeted drug delivery.

Main Methods:

• Literature review focusing on cyclodextrins in drug delivery.
• Analysis of chemical properties, solubilization, stabilization, and permeation mechanisms.
• Examination of toxicological profiles for ocular and nasal routes.
• Summary of recent advancements in CD-based nanocarrier systems.

Main Results:

• CDs significantly improve drug solubility and bioavailability.
• CDs facilitate targeted drug delivery and controlled release.
• CD formulations show promise for non-invasive ophthalmic and nasal drug delivery.
• CD-based nanocarriers offer advanced targeted delivery capabilities.

Conclusions:

• Cyclodextrins are highly effective excipients for enhancing drug delivery, particularly for poorly soluble compounds.
• CDs offer significant advantages for non-invasive routes like ophthalmic and nasal administration.
• The development of CD-based nanocarriers represents a significant advancement in targeted drug delivery and nanomedicine.
