Abstract
Improved processes for obtaining the sustained release of pharmaceuticals from polymer matrices comprising the utilization of such steps as will allow the formation of solid solutions between pharmaceutical and its matrix or, conversely and in a proper case, substantially avoiding formation of any solid solution between the matrix and pharmaceutical. The advantage of such processes is the greater predictability of qualitative and quantitative nature of release rates of products formed therewith.
