U.v .-visible spectrophotometric studies of the interactions of Naproxen, Ibuprofen and Panadol with α-cyclodextrin , β-cyclodextrin, γ-cyclodextrin and dimethyl β- cyclodextrin enable the determination of stability constants of inclusion complexes when their formation gives rise to appreciable spectral changes. The magnitudes of the stability constants are discussed in terms of the relative sizes and the chemical natures of the cyclodextrins and the included molecules.
