To the Editor: Solid solution systems have been of pharmaceutical interest in recent years (1-7). The thermodynamic basis for solid solution systems is given in standard texts on solid-state physics or chemistry; e.g., Zhdanov (8) listed the expression for the free energy, F , at temperature T O K of a system containing x mole fraction A and (1x ) mole fraction B as: (Eq. 1) where:

N = Avogadro's number Z = coordination number Vn.4 = interaction energy between two A mole-V B H = interaction energy between two B mole-V A I j = interaction energy between an A and a B
