New alkyl carbonates of

-cyclodextrin have been obtained. These derivatives show lower haemolytic effect than the parent

-cyclodextrin. The complexation behaviour was tested with three important drugs, namely: progesterone, diazepam and flurbiprofen. DSC analyses were consistent with the inclusion complex formation.
diazepam - flurbiprofen - haemolysis - progesterone - solubilising agents
