Background: Anti-inflammatory drugs can be ineffective in treating some inflammatory conditions.
Improved drug delivery systems like cyclodextrins (CDs) could enhance their efficacy and safety.
Objective: We conducted a systematic review to evaluate the anti-inflammatory activity of compounds complexed
in CDs, analyzing whether these complexes improved their pharmacological action.
Methods: The search terms ‘Anti-inflammatory Agents’, ‘Cyclodextrins’ and ‘Drug effects’ were used to retrieve
articles in SCOPUS, PUBMED, MEDLINE and EMBASE.
Results: Forty-four papers were identified. In the in vivo and clinical studies, there was greater efficacy for complexed
drugs when compared to control groups or uncomplexed drug, decreasing inflammation and inflammatory
mediators. Through a meta-analysis, the preclinical studies demonstrated that the complexed drug had a significantly
(p<0.001) greater anti-inflammatory effect than the non-CD-complexed drug.
Conclusion: The use of CDs can improve the action of anti-inflammatory compounds and it can also be a way to
reduce the side effects, therapeutic doses and toxicity.
