ABSTRACT:
Sustained-released delivery forms comprising the reaction product of a Lewis acid salt with a Lewis base salt at the phase interface of their respective aqueous and non-aqueous solution to form an anisotropic high molecular weight salt of the acid and base and a neutral salt of the inorganic cation and anion in what is termed a "double decomposition" or "salt exchange" reaction.
