b cyclodextrin solubility





The higher solubility afforded by -cyclodextrin allows us to limit the volume of injection to 1 mL, and 3 different strengths (25, 50, and 75 mg/vial) are available. In general, the water-soluble cyclodextrin derivatives form A-type phase- solubility profiles while the less soluble natural cyclodextrins frequently form B-type profiles. The hydrogen bond strengths are -cyclodextrin < -cyclodextrin < - cyclodextrin.The low solubility of -cyclodextrin, when compared to - and -cyclodextrins presents a puzzle [915].
