Ion-associate complexes of atropine sulphate (I), diphenhydramine HCl (II), tolazoline HCl (III) and levamisole HCl (IV) with potassium tetraiodomercurate were precipitated and their solubilities were studied as a function of pH, ionic strength and temperature. Saturated solutions of each ion-associate
