Open the CIPO recordAbstract From the Canadian patent
Inclusion complexes of hydroxypropyl hydroxy-, ethyl, glucosyl, maltosyl or maltotriosyl derivatives of .beta.- or .gamma.-cyclodextrin with the reduced biooxi-, dizable, blood-brain barrier penetrating lipoidal, forms of dihydropyridine ? pyridinium salt redox systems for brain-targeted drug delivery provide a means for stabilizing the redox systems particularly, against oxidation. The redox inclusion complexes also provide a means for decreasing initial drug concentrations in the lungs after administration of the systems leading to decreased toxicity. In selected instances complexation results in substantially improved water solubility of the redox systems as well.
