Abstract: The present study comprises determination of stability constant and the thermodynamics of interaction of Fluoroquinolones antibiotics, Flumequine, Ciprofloxacin, Levofloxacin and Sparfloxacin with transition metal Mn(II), Co(II), Ni(II), Cu(II) and Zn(II) ions. Among the outstanding achievement of human being is the discovery of antibiotics. It is called miracle drugs for its effectiveness and efficiency is controlling several diseases in plants, animals and human beings. Metal ion have many important functions in biological system so detailed physicochemical investigation of the metal complexation with antibiotics is worth study. The association of the metal with ligands produces observable changes in the chemistry of both the metal ion and the ligand and hence changes in various physical and chemical properties. A wide variety of physical methods have been applied to the study of metal ligand interactions. Potentiometric pH titration technique is the most convenient and versatile method. In this method, the substance is titrated with alkali twice, first in the absence and then in the presence of the metal ion. Because the metal cation displaces the hydrogen cation, the second titration curve lies at lower pH-value than the first one. The difference between these curves can be used for the calculation of proton and metal stability constant of ligands employing some mathematical calculations. The formation of 1:1 and 1:2 metal ligand complexes are found to be formed in 50 %( v/v) methanol water system for each case. The stability constant values for metal-ligand system compared at three temperatures, it is found that value of stability constant decreases with increasing temperature. newline
