The complexes of famotidine and Zn²⁺ was investigated using D.C. polarography. The polarographic technique was used to determine the kinetic parameters (K⁰_fh, αn) and thermodynamic parameters such as enthalpy change (ΔH^#), free energy change (ΔG^#) and entropy change (ΔS^#) of Zn²⁺ complexes with famotidine. The electrode processes were irreversible and diffusion controlled.
