I have studied the swelling behaviour and drug release pattern from hydroxypropyl beta cyclodextrin where I have found that the swelling and release % was more in basic compared to acidic. It would be helpful for me if anyone can explain
Bably Khatun You may refer to the below mentioned papers
1. https://www.dovepress.com/development-of-beta-cyclodextrin-based-hydrogel-microparticles-for-sol-peer-reviewed-fulltext-article-DDDT#
2. https://www.ncbi.nlm.nih.gov/pmc/articles/PMC5456989/
The explanation is given beautifully there. Hope this will help you.
Thank you di Nibedita Banik
