“…Many formulation strategies were investigated to improve solubility and bioavailability of CyA such as complexation with cyclodextrin (Matilainen et al, 2006), and particulate delivery system including microspheres (Yeung and Chaw, 2009) and liposome (Czogalla, 2009). The formulation of CyA in nanoparticles dosage has received much attention in the last few years mainly due to its ability to improve bioavailability and could be a better alternative to current delivery system.…”

“…10 Japán és finn kutatók ismerték fel elsõként, hogy a ciklosporin vízoldékonysága alfaciklodextrinek, különösen a 2-hidroxipropil-alfaciklodextrin jelenlétében oly mértékben nõ, hogy az már a terápiás használhatóságot is biztosítja. 11,12 A TT-232 jelzésû ígéretes sztomatosztatin analóg hepta-peptid 13 vizes oldatban fellépõ aggregációja metil-béta-ciklodextrinnel hatékonyan gátolható. Az 5. ábra a hepta-peptid aggregációját mutatja pufferben és dimetil-béta-ciklodextrint tartalmazó pufferben, 6 órás keverés után.…”
