Viscosities (η) and densities (ρ) of atenolol and propranolol hydrochloride in water and in concentrations (0.05 M) and (0.1 M) aqueous solution of threonine have been used to reform different important thermodynamic parameters like apparent molal volumes ϕ_v, partial molal volumes at infinite dilution ϕ_v̊, transfer volume ϕ_v̊(tr), the slop S_v, Gibbs free energy of activation for viscous flow of solution ΔG*_1,2 and the B-coefficient have been calculated using Jones-Dole equation. These thermodynamic parameters have been predicted in terms of solute-solute and solute-solvent interaction.
