The present invention relates to a complex of Ag, Zn, Cu, Pt, Au, oxides, hydroxides and salts thereof; with a cyclodextrin of formula (I) as defined in claim 1. Advantageously, the complex further comprises an organic therapeutic agent, preferably an antibiotic agent. The complexation according to the invention advantageously maintains the metal: organic therapeutic agent molar ratio. Even more advantageously, the complexation according to the invention enhances the intrinsic aqueous solubility of the metal-organic therapeutic agent association. The present invention further relates to compositions, pharmaceutical compositions and adequate formulations and uses thereof as well as devices comprising a complex of the invention. Lastly, the invention relates to a method for improving the aqueous solubility of a metal selected from Ag, Zn, Cu, Pt, Au, Ru, As, Sb, Bi, Ti, V, Ni, Hg, Pb, Co, oxides, hydroxides and salts thereof by providing a reaction mixture comprising said metal, an aqueous medium and a cyclodextrin of formula (I) as defined in claim 1.
