By means of spectrophotometric methods it was found that ofloxacin reacts with copper(II) ions to form complexes with molar ratios of ofloxacin: Cu(II) of 1:1 at pH 4.00, 2:1 at pH 7.02 and 3:1 at pH 8.30. The stability constants of the complexes were determined. The formation of ofloxacin:Cu(II) 1:1 and 3:1 complexes was confirmed by a polarographic method and the corresponding overall stability constant was evaluated.
