Abstract
The aim of the study was to synthesize and characterization the inclusion complexes of amlodipine besylate (AML) drug with β-cyclodextrin (β-CD) and γ-cyclodextrin (γ-CD) which has antioxidating activity property. The guest/host interaction of AML with β-CD and γ-CD in order to complexation drug in β-CD and γ-CD were investigated. The interaction inclusion complexes was characterized by fourier transform infrared and ultraviolet–visible spectroscopies. The formation constant was calculated by using a modified Benesi–Hildebrand equation at 25 °C. The stoichiometry of inclusion complexes was found to be 1:1 for β-CD and γ-CD with AML drug. The antioxidant activity of AML drug and its inclusion complexes were determined by the scavenging of stable radical 2,2′-diphenyl-1-picrylhydrazyl (DPPH·). Kinetic studies of DPPH· with AML and CDs complexes were done. The experimental results confirmed the forming of AML complexes with CDs also these indicated that the AML/β-CD and AML/γ-CD inclusion complexes was the most reactive than its free form into antioxidant activity.
