Design and evaluation of cyclodextrin-based drug formulation.

Area of Science:

• Pharmaceutical Science
• Drug Delivery Systems
• Supramolecular Chemistry

Background:

• Cyclodextrins (CyDs) are versatile pharmaceutical excipients with hydrophilic, hydrophobic, and ionic derivatives.
• Their multi-functional characteristics and bioadaptability allow for the improvement of drug molecules' undesirable properties.
• CyDs achieve this through the formation of inclusion complexes or CyD/drug conjugates.

Purpose of the Study:

• To review the current applications of cyclodextrins in drug formulation design and evaluation.
• To highlight the role of CyDs in enhancing drug absorption across biological barriers.
• To discuss the ability of CyDs to control drug release profiles and facilitate targeted drug delivery.

Main Methods:

• Literature review of cyclodextrin applications in pharmaceutical formulations.
• Analysis of studies focusing on CyD-mediated drug absorption enhancement.
• Evaluation of research on CyD-based controlled and targeted drug delivery systems.

Main Results:

• Cyclodextrins effectively enhance drug absorption across various biological barriers.
• CyD-based formulations demonstrate significant control over drug release rates and time profiles.
• Targeted drug delivery is achievable using specific cyclodextrin derivatives and strategies.

Conclusions:

• Cyclodextrins are valuable tools in pharmaceutical formulation for improving drug efficacy and patient compliance.
• The application of cyclodextrins in drug delivery is expanding, offering solutions for bioavailability and targeting challenges.
• Further research into novel cyclodextrin derivatives and formulations will continue to advance drug delivery technologies.
