Molecular recognition of funarizine dihydrochloride and β-cyclodextrin inclusion complex by NMR and computational approaches

Flunarizine dihydrochloride (FLN) is used in the prophylactic treatment of migraine, vertigo, occlusive peripheral vascular disease and epilepsy. Cyclodextrins (CDs) are chiral, truncated cone shaped macrocycles known for their inner hydrophobic and outer hydrophilic site.
