title: Hyperbranched polyamidoamines containing beta-cyclodextrin for controlled release of chlorambucil.
abstract: This work is focused on the controlled drug release behavior of hyperbranched HPMA in the presence of beta-CD. Hence, three HPMA-beta-CDs and a pure HPMA were synthesized by Michael addition polymerization. As a model drug, CLB (an anti-cancer drug) was loaded into them via a solution method for in vitro release studies. The DSC results indicate that the CLB/polymer interactions are at the molecular level. Loading CLB into these polymers results in an evident increase in their glass transition temperatures, and DeltaT(g) depends on the beta-CD content. The controlled-release experiments show that the presence of beta-CD can appropriately slow the release of CLB from HPMA-beta-CDs and adjust the ratio of CLB released in total drug loading.
